How to set up the system
Follow the steps below to set up the evaluation kit.
Step 1.
Mount the STEVAL-CTM004V1 power board heatsink.
Use standard thermal interface material or a graphite sheet for high thermal conductivity
Step 2.
Connect the STEVAL-CTM004V1 power board with the STEVAL-CTM006V1 driver board.
–
use connectors CON5, CON6, CON7 and J3 on the STEVAL-CTM004V1 power board
–
use connectors CON1, CON3, CON4 and J2 on the STEVAL-CTM006V1 driver board
Step 3.
Connect the control board:
–
If you use the STEVAL-CTM001V1C control board (not included in the kit):
◦
use connectors J1 and J4 on the STEVAL-CTM006V1 driver board
◦
use connectors CON3 and CON1 on the STEVAL-CTM001V1C control board.
–
If you use a control board that is not the STEVAL-CTM001V1C:
◦
Use connector J1 on the driver board.
Step 4.
Mount the STEVAL-CTM005V1 bus link capacitor board on the STEVAL-CTM004V1 power board
Step 5.
Set up the STEVAL-CTM001V1C control board (optional, if present).
–
close jumper SW5 in the default position (indicated near the switch)
–
connect ST-LINK to the CON14 connector
–
connect the USB to serial converter to the P2 with a serial cable DB9 female to female
Step 6.
Set up the STEVAL-CTM006V1 driver board.
–
close jumper S1, S2 or S3 to read one of the three NTCs on the power stage
–
connect a 12 V DC power supply to the JP1 connector and turn on the power supply
Step 7.
Connect the flat cable between CON2 on the STEVAL-CTM006V1 driver board and J1 on the STEVAL-
CTM008V1 current sensing board.
Step 8.
Connect a 48 V
DC
power supply to the STEVAL-CTM006V1 driver board.
Step 9.
Connect the phase motor cables to the STEVAL-CTM004V1 power board.
7.1
Connectors
In addition to the connector used for the supply voltage, the driving board has connectors to plug it to the power
board and the control board, and to receive external signals.
•
Connector for supply voltage: provided at JP1 (8 to 36 V).
•
Connectors to the power board:
–
CON1, CON3 and CON4: for power MOSFET driving and NTC sensing.
–
J2: connector for DC bus voltage sensing (fpr undervoltage and overvoltage protection).
•
Connectors to the control board
–
J1: motor control connector, including signals like fault management, bus voltage monitoring, power
board temperature sensing and current sensing.
–
J4: connector used for mechanical robustness when a control board (e.g., STEVAL-CTM001V1C, not
included in kit) is plugged but not electrically connected.
•
Connectors for external signals
–
CON8 (ENC/HALL connector): to receive external signals from Encoder/Hall sensors and provides
+3V3 or +5V supply voltages.
–
CON2 (CURRENT SENSING connector): to receive current signals from the external current sensor
board and provide a +5V supply voltage.
