Motor Drive Reference Design Kit
INTRODUCTION
The Motor Drive Reference Design Kit is comprised of three power boards that can be driven by a control board via six in-line connectors. The power boards can work directly from an AC or DC power supply (the PowerBD -3000 uses only DC power). The auxiliary power supply is located on the power boards and works with applications rated above 50VDC. Some of the many advantages include: The kit is quick to set up and install, and is easy to run. The design is re-usable (the Gerber files are available for free). The original partition design between the power board and the control board provides very effective system noise immunity. Note: Please read the SAFETY AND OPERATING INSTRUCTIONS section before attempting any operation with this manual. The Motor Drive Reference Design Kit provides customers with a reference design for a three-phase power inverter using ST's dedicated chip set. When they are connected to a motor, they allow the user to demonstrate smooth, silent, and efficient motor operation. The design boards are well-suited for several kinds of applications which required six-step commutation or 6-signal PWM (sine wave-modulated) output, including 3PH AC Induction motor control, 3PH PMDC/AC or BLDC/AC (Trapezoidal driven) motor control, 3PH PMAC or BLAC (sinusoidal driven) motor control, and Single- and 3-phase UPS (Uninterruptable Power Supply). This kit offers customization options as well, making it an excellent choice as an original platform for a more complete and dedicated system. Special care has been taken during the layout process to provide a very low level of interference between the Power and the Signal noise. This makes the system quite solid under almost all operating conditions. There are three (3) power boards for 3-phase inverters of different power rates and a control board: PowerBD-300 (300W nominal rated power) PowerBD-1000 (1000W nominal rated power) PowerBD-3000 (3000W nominal rated power) C ontrolBD -7FMC2 WARNING: The high voltage levels used to operate the motor drive could present a serious electrical shock hazard. This kit must be used only in a power laboratory only by engineers and technicians who are experienced in power electronics technology.

ELECTRICAL MOTOR CONTROL DEMONSTRATION SETUP
Most of the system features are covered in this user manual, starting from the main power supply frontend to the power stages, including the operation of the +5V/+15V power supply and microcontroller. This kit includes the following key components: Motor control-dedicated microcontrollers L6386 half-bridge drivers 60V MOSFET or 600V Insulated Gate Bipolar Transistor (IGBT) VIPer12 auxiliary supply smart power switch Small-Signal Bipolar Transistors STTH108 and BAS70W Diodes 78L05 voltage regulator M95040 EEPROM memory P6KE400A and 1.5KE400A TransilTM diodes (optional) WARNING: The starter kit has no isolation shield or any other type of protection case. The demonstration board must be handled very carefully, as high potential (energy) parts are open and can be touched. The user MUST avoid connecting or removing cables during operation of an electric motor, or touching any part of the system when it is connected to the main power supply. Note: After turning the motor off, the DC-link capacitor may still hold voltage for several minutes (refer to the LEDs on the control board - Figure 9., page 34). Note: Do NOT expose the kits to ambient temperatures of over 35C, as this may harm the components or reduce their lifetimes. For more information on the demonstration software and libraries, refer to Application Notes AN1291, AN1083, and AN1276. Environmental Considerations The Motor Drive Reference Design Kit must only be used in a power laboratory. The high voltage used in any AC drive system presents a serious shock hazard. A complete laboratory setup consists of an isolated AC power supply, the Reference Design Kit, an AC Induction motor, and isolated (laboratory) power supplies for +15V (as needed). The Kit is not electrically isolated from the AC input. This topology is very common in AC drives. The microprocessor is grounded by the integrated Ground of the DC bus. The microprocessor and associated circuitry are hot and MUST be isolated from user controls and serial interfaces. Note: Any measurement equipment must be isolated from the main power supply before powering up the motor drive. To use an oscilloscope with the Kit, it is safer to isolate the AC supply AND the oscilloscope. This prevents a shock occurring as a result of touching any SINGLE point in the circuit, but does NOT prevent shocks when touching TWO or MORE points in the circuit. An isolated AC power supply can be constructed using an isolation transformer and a variable transformer. A schematic of this AC power supply is in the Application Note, "AN438, TRIAC + Microcontroller: Safety Precautions for Development Tools." (Although this Application Note was written for TRIAC, the isolation constraints still apply for fast switching semiconductor devices such as IGBTs.) Note: Isolating the application rather than the oscilloscope is highly recommended in any case.

Power Board Connections Note: Before supplying power to the boards, verify the connection integrity and make sure there are no unintended earth/ground loops caused by peripheral (e.g., test) equipment (e.g., PC or oscilloscope). C ables C hoose the appropriate gauge wiring for the motor's current ratings. N ote: Electrostatic charges may accumulate on a floating motor and increased voltage may be present due to energized capacitors which need to be allowed to discharge.
Straps and Jumpers Several jumpers allow the two bulk capacitors to function in serial (current with one path to follow) or parallel (current with at least two paths to follow) configuration: Three jumpers allow for operation with Double Rectification. This is enabled by soldering jumpers J1-J3, J9-J10, and J4-J5, and keeping J12-J13 open (see Figure 6., page 26, Figure 7., page 29, and Figure 8., page 32 ). This configuration is recommended when the main power supply voltage ranges from 180VAC to 260VAC. Three jumpers enable the Voltage Doubler. This is enabled by soldering jumpers J1-J6, J7-J11, and J12-J13, and keeping J4-J5 open (see Figure 6., Figure 7., and Figure 8.). This configuration is recommended when the main power supply stays below 130VAC. This will double the main power supply voltage and, consequently, the output voltage available to the motor. For example, a main power supply voltage of 120VAC will produce a bus voltage of about 320VDC. This higher output voltage allows the motor to draw less current. Note: Care must be taken when operating the motor in this mode. Input voltage must be kept below 135VACRMS. If this value is exceeded for any reason, the bulk capacitors will be protected by the optional TransilTM diode TR1 (P6KE400A D0-15 or 1.5KE400A D0-201; see Figure 6., Figure 7., and Figure 8.). It will clamp to the high voltage DC bus, causing the input protection fuse to blow. Bulk Capacitor Jumpers AC Input AC Input bulk capacitors must be installed according to the line voltage and power ratings BEFORE plugging in the board. DC Input DC Input bulk capacitors must be installed according to the supply line inductance and soft-start conditions BEFORE plugging in the board.

Power Board Switches Table 2., page 8 lists the appropriate power switches which must be installed on the power board. The packaging with the "FP" suffix are fully insulated by molding, and do not require any external insulators. The D2 packages are insulated from each other by the PC board (PCB). Note: Care must be taken to ensure TO220, TO247, and MAXTO247 are NOT insulated. They require external insulator pads (i.e., polyimide foil between the heat sink and power switches). Setting up the Control Board The gate drive resistor value is 100. This must be adjusted according to the power switch gate capacitance and the expected switching dV/dt. Figure 5. allows the user to determine the correct value, depending on the maximum dV/dt specified for the motor. Note: The L6386 High Voltage High and Low Side Driver requires a power supply voltage of 15VDC (typ). If the motor operation requires less than 14VDC, the L6387 is preferred because the operation supply voltage range goes down to 6VDC. Figure 5. STGP14NC60KD Gate Resistor Turn OFF Voltage Slope

ControlBD-7FMC2 and 3PH AC INDUCTION MOTOR CONTROL SOFTWARE (Open Loop) v1.0
The software operates the ControlBD-7FMC2 board in a standalone manner, with the operation controlled by the Push-button S2 and the on-board trimmer potentiometers (P2, P3). S2 controls ON/OFF function, P2 sets the voltage, and P3 sets the frequency. Download the Firmware into the ST7FMC Microcontroller For configuring the ControlBD-7FMC2 as 3PH AC Induction motor controller, it is necessary to download the proper binary source code (.S19 file) into the microcontroller. For open loop operations, the binary file provided with AC software library can be downloaded into the ST7FMC code memory as it is. This can be done with the Datablaze Programmer utility. Please refer to User Manual UM0121, "ControlBD-7FMC2 Reference Design Graphical User Interface (GUI)" for details. The settings provided for this binary code can be viewed in the "Basic Parameter" window of the Reference Design RDK-GUI tool when the "3 PH AC Induction" motor option has been selected. Start-up Procedure 1. C onnect a 3 phase induction motor (mechanically unloaded) to connectors FST4, FST6, and FST7. Sequencing is arbitrary and the direction of rotation will be set later. 2. R emove the control board jumpers J11 and J12, and set jumper J10 between 1-2. 3. Set all potentiometers (P2 and P3) to full Counter Clockwise (CCW) position. Potentiometer P3 is the FREQUENCY setting. Full CCW to full Clockwise (CW) corresponds to a range of 10Hz to 340Hz, with increments of 1Hz. 4. Monitor one of the three motor currents with an isolated current probe. 5. Apply the main voltage supply to connectors FST3 and FST5, or a DC voltage supply to connectors FST1 (+) and FST2 (). N ote: In the Idle state, a green LED will be flashing, and then it will stay on. 6. Set P3 to about 60Hz (1/4 turn CW). 7. Switch ON S2. N ote: In the Run state, the red LED will light up. The motor current should remain at zero, although some switching noise may be observed. 8. Slowly rotate potentiometer P2 CW to begin increasing the Voltage setting from zero. You should start to see a 60Hz (approximately) current build-up in the motor and then the motor should begin to rotate. 9. C ontinue to increase the setting until the motor has come up to the expected speed for this excitation frequency. Keep in mind that some slip will be expected. The current waveform should remain fairly sinusoidal. If the waveform becomes highly distorted or exceeds the motor rating, decrease the Voltage setting. WARNING: The entire circuit board and motor output terminals are always "hot" with respect to earth ground, even when the drive is in a stopped condition.

Commands If the S2 button is pushed, it starts the motor. When the drive is running and the S2 button is pushed, it stops the motor. The controller always enforces a maximum slew limit on changes to the frequency of excitation applied to the motor. In practice this softens the motion of the motor, causing it to ramp up to the commanded frequency (speed) when going from STOP to RUN. Decreasing the frequency and voltage applied to the motor slowly decreases the speed (to zero). Note: It is acceptable to start or stop the drive at any time and speed because of the slew limit. Motor Direction If you wish to change the running direction of the motor, simply disconnect the drive from the main voltage supply, wait for the bulk capacitors to discharge, then swap any two of the three motor wires. Potentiometer Commands P2. Sets the Voltage applied from the minimum value (0) to the maximum VBUS. This setting is internally limited with a V/F curve (refer to User Manual UM0121). P3. Sets the motor frequency and thus the motor speed. Use P3 to set the stator frequency as well. The contribution of P3 is 10Hz when it is in the maximum CCW position and will increment downward by 1Hz resolution to reach 340Hz by rotating the potentiometer to full CW position.

Since this is voltage mode, open loop control, it sets the PWM duty cycle from 0% to 97%. In order to sense the back EMF, the motor must first be started and brought up to a certain speed where the back EMF voltage (BEMF) can be detected. Before the motor is started, the controller will bring the rotor to a predetermined position. This is called the "alignment phase". After the rotor is in the alignment position, a fixed accelerating commutation command will be invoked by the microcontroller. If the acceleration rate is correct, the motor will be accelerated until the microcontroller can detect the BEMF and switch to auto-switched mode. Note: When PowerBD-300 is used with high voltage, it is necessary to add a STTH108 diode in series with a 1K ¼ resistor, and connect it in parallel with the BEMF resistors as is done for the PowerBD-1000.

APPENDIX A. PowerBD-300 CHARACTERISTICS AND SCHEMATIC
Front-end The front-end section allows supply voltage from the AC source via FST3 and FST5, or from the DC source via FST1 and FST2. The Jumper settings are: The DC source is preferred during development. When operating with low DC voltage (<30VDC), external 15V auxiliary voltage must be supplied via CON2, and J14 and J8 must be removed. W hen operating with double rectification, three straps will be installed between J4-J5, J1-J3, and J9J10, respectively. W hen operating with the voltage doubler, three straps will be installed between J1-J6, J7-J11, and J12-J13, respectively. The Inrush current protection is provided by NTC1. Auxiliary Power Supply This Buck converter uses a VIPer12A regulator that provides charging current for reliable start-up capability, an integrated PWM controller, and thermal as well as over-current protection. The PWM controller is very simple and does not require an external feedback compensation network. The regulation circuit is decoupled from the supply circuit using a separate diode (D2) and capacitor (C2) to supply the zener diode (D3) on the FB pin. D1 is a low voltage diode (e.g. 1N4148) that allows the voltage on VDD to reach the start-up value. D2 and C2 are essentially used to detect peak output voltage. To prevent disturbance resulting in possible output over-voltage or incorrect start-up, a zener diode (D6) is connected across the output circuit. For further details, refer to Application Notes AN1317 and AN1357. An insulated axial inductor may be used to provide a voltage oscillation filter. This type of inductor meets low cost considerations but it produces a high series resistance that adversely affects the efficiency of the converter. The current capacity of this type of inductor is determined, for any given package, by its series resistance. For example, a 1.5mH inductor has a current capacity of about 100mA since its series resistance is about 30R. The 5V zener diode (D5) decreases the voltage regulator temperature for lifetime-sensitive applications. The 5V is supplied from the 15V using a L78L05 three-terminal positive regulator. It provides with internal current limiting and thermal shutdown. The 5V Zener diode D5 decreases the voltage regulator temperature for lifetime-sensitive applications. Note: When the line voltage is lower than 30V, an external 15V auxiliary power supply is mandatory. It must be plugged into CON2, and J14 and J8 must be removed.

Power Stage The board is designed to fit D2Pack packages, but DPack packages may also be assembled as well for testing purposes (see Table 2., page 8 to select a suitable part number). The default value of the sense resistor is 0.1R. It must be adjusted depending on actual operating conditions. The RSENSE value, together with resistors R38, R20, and R14 (put in the ControlBD-ST7FMC2), sets the maximum limit threshold for the motor current above which a hardware overcurrent protection event is validated. In this condition, the red LED starts to blink and the controller passes into the Reset state, where the motor does not run anymore. To rearm the controller, the AC (or DC) power supply must be turned off and it is necessary to wait for the bulk capacitors to discharge completely. For the PowerBD-300W, the maximum limit for the motor current is fixed at 7A (peak value). Note: If the board is going to drive a sensorless BL(PM)DC motor, six phase voltage sense resistors must be present (default configuration). If the power board is linked to three Hall Effect sensors via CON1, resistors R14, R15, R16, and capacitors C22, C23, and C24 (1nF) in the ControlBD-7FMC2 must be assembled while removing resistors R7, R10, and R12. To provide over-temperature protection during the Power Stage, U1 (LM335) must be installed after assembly of Q5. It is a precision temperature sensor circuit which operates as a 2-terminal zener diode and has the following features: can be easily calibrated if needed; breakdown voltage directly proportional to the absolute temperature at 10mV/K; dynamic impedance of less than 1 and operates within a range of current from 450A to 5mA without alteration of its characteristics; and if calibrated at +25C, it has a typical error rate of less than 1C over a 100C temperature range. Unlike other sensors, the LM335 has a linear output. The over-temperature protection threshold can be adjusted via R17 and R18 on the control board.

APPENDIX B. PowerBD-1000 CHARACTERISTICS AND SCHEMATIC
Front-end The front-end section allows supply voltage from the AC source via FST3 and FST5, or from the DC source via FST1 and FST2. The Jumper settings are: The DC source is preferred during development. When operating with low DC voltage (<30VDC), external 15V auxiliary voltage must be supplied via CON2, and J14 and J8 must be removed. W hen operating with double rectification, three straps will be installed between J4-J5, J1-J3, and J9J10, respectively. W hen operating with the voltage doubler, three straps will be installed between J1-J6, J7-J11, and J12-J13, respectively. The Inrush current protection is provided by resistor R6. This resistor is bypassed with Relay12A after voltage ramp-up. Auxiliary Supply This Buck converter uses a VIPer12A regulator that provides charging current for reliable start-up capability, an integrated PWM controller, and thermal as well as over-current protection. The PWM controller is very simple and does not require an external feedback compensation network. The regulation circuit is decoupled from the supply circuit using a separate diode (D1) and capacitor (C2) to supply the zener diode (D3) on the FB pin. D1 is a low voltage diode (e.g. 1N4148) that allows the voltage on VDD to reach the start-up value. D2 and C2 are essentially used to detect peak output voltage. To prevent disturbance resulting in possible output over-voltage or incorrect start-up, a zener diode (D6) is connected across the output circuit. For further details, refer to Application Notes AN1317 and AN1357. An insulated axial inductor may be used to provide a voltage oscillation filter. This type of inductor meets low cost considerations but it produces a high series resistance that adversely affects the efficiency of the converter. The current capacity of this type of inductor is determined, for any given package, by its series resistance. For example, a 1.5mH inductor has a current capacity of about 100mA since its series resistance is about 30R. The 5V is supplied from the 15V using an L78L05 three-terminal positive regulator. It provides internal current limiting and thermal shutdown. The 5V zener diode (D5) decreases the voltage regulator temperature for lifetime-sensitive applications. Note: When the line voltage is lower than 30V, an external 15V auxiliary power supply is mandatory. It must be plugged into CON2, and J14 and J8 must be removed.

UM012 2 - USER MANUAL
Power Stage The board is designed to fit TO220 packages (see Table 2., page 8 to select a suitable part number). The default value of the sense resistor is 0.047R. It must be adjusted depending on actual operating conditions. The RSENSE value, together with the resistors R38, R20, and R14 (put in the ControlBD-ST7FMC2), sets the maximum limit threshold for the motor current above which a hardware overcurrent protection event is validated. In this condition, the red LED starts to blink and the controller passes into the Reset state, where the motor does not run anymore. To rearm the controller, the AC (or DC) power supply must be turned off and it is necessary to wait for the bulk capacitors to discharge completely. For the PowerBD-1000W, the maximum limit for the motor current is fixed at 14.5A (peak value). Note: If the board is going to drive a sensorless BL(PM)DC motor, six phase voltage sense resistors must be present. If the power board is linked to three Hall Effect sensors via CON1, resistors R19, R20, R21, and capacitors C22, C23, and C24 (1nF) in the ControlBD-7FMC2 must be assembled while removing resistors R7, R10, and R12. To provide over-temperature protection during the Power Stage, a temperature sensor (e.g., LM335Z) must be installed on the heat sink and connected to CON3. The LM335Z is a precision temperature sensor circuit which operates as a 2-terminal zener diode and has the following features: can be easily calibrated if needed; breakdown voltage directly proportional to the absolute temperature at 10mV/K; dynamic impedance of less than 1 and operates within a range of current from 450A to 5mA without alteration of its characteristics; and if calibrated at +25C, it has a typical error rate of less than 1C over a 100C temperature range.

Power Stage The board is designed to fit TO247 packages (see Table 2., page 8 to select a suitable part number). The default value of the sense resistor is 0.02R. It must be adjusted depending on actual operating conditions. The RSENSE value, together with the resistors R38, R20, and R14 (put in the ControlBD-ST7FMC2), sets the maximum limit threshold for the motor current above which a hardware overcurrent protection event is validated.

To rearm the controller, the AC (or DC) power supply must be turned off and it is necessary to wait for the bulk capacitors to discharge completely. For the PowerBD-3000W, the maximum limit for the motor current is fixed at 34A (peak value). Note: If the board is going to drive a sensorless BL(PM)DC motor, six phase voltage sense resistors must be present. If the power board is linked to three Hall Effect sensors via CON1, resistors R19, R20, R21, and capacitors C22, C23, and C24 (1nF) in the ControlBD-ST7FMC2 must be assembled. To provide over-temperature protection during the Power Stage, a temperature sensor (e.g., LM335Z) must be installed on the heat sink and connected to CON3.

APPENDIX D. ControlBD-7FMC2 CHARACTERISTICS AND SCHEMATIC
Gate Drive Circuit Each half bridge is driven by an L6386 high voltage integrated circuit which is able to operate at voltages of up to 600V. The logic inputs are CMOS logic-compatible, and the driving stages can source current up to 400mA and sink current up to 600mA. It integrates one upper and one lower side channel with two under-voltage lockout circuits and a comparator referenced to 0.5V. The bootstrap auxiliary supply is integrated in the IC, which helps to reduce the number of parts on the PC Board, therefore increasing the layout flexibility. This function is normally accomplished by a high voltage, fast recovery diode. The L6386 contains a patented integrated structure which replaces the external diode. It is comprised of a high voltage DMOS, driven synchronously with a low side driver (LVG) (refer to Application Note AN1299). An internal charge pump provides driving voltage to the DMOS. A diode connected in series to the DMOS is added to avoid inadvertent power-up, so using an external fast recovery diode can be avoided (usually exhibits high leakage current). Gate drive resistors R1, R3, R5, R7, R9, and R11 have been set to 100. This value must be adjusted according to Figure 5., page 13. The cell comprised of Q1-C1-R2 is used to split the issues of canceling the switching cross-conduction and controlling the winding dV/dt, whatever the operating conditions and IGBT junction temperature. The cell provides a low impedance path to the Miller current when the adjacent power switch is turning ON, canceling any cross-conduction current. This way, the half-bridge power ON switching dV/dt is only defined by the gate drive resistor value produced by R1, R3, R5, R7, R9, and R11. The comparator integrated in the L6386 (IC2) provides output with over-current protection which shuts down the three half-bridges. If the voltage applied to pin 6 reaches 0.5V (typ), the Diagnostic output (pin 5) is pulled down, as well as the shut-down input (pin 2). The same circuit can be implemented to provide over-temperature protection. This is done via the IC3 comparator input. An OR function is made paralleling the diagnostic output of IC2 and IC3. In regular operation this protection is never triggered because the microcontroller is monitoring the temperature sensor via PA3. A third type of protection may be implemented using the IC1 input comparator (e.g., high side overcurrent protection with the PowerBD-1000 or PowerBD-3000).
Microcontroller User Interfaces WARNING: The Reference Design kit has no isolation shield or any other type of protection case. The demonstration board must be handled very carefully, as high potential (energy) parts are open and can be touched. The user MUST avoid connecting or removing cables during operation of an electric motor, or touching any part of the system when it is connected to the main power supply.
