Appendix B

Test procedure

The software attached with this application note can be downloaded and tested on the

ST7FMC starter kit. The test procedure is as follows:

1.

Configure the jumpers for sensored BLDC mode.

2.

Set W12 to FIXED

3.

POT1 sets the current reference. Set it to a middle position

4.

RV1 sets magnitude reference for sine output. Set to zero (CCW)

5.

RV2 sets load angle. Set to mid position (0°). Turning CW increases the load angle and

CCW takes it negative (max / min is +/-90°)

6.

Yellow button SW1 is the ON/OFF switch. Press it to turn ON.

7.

Turn RV1 CW and motor starts running

8.

Change POT1, RV1 and RV2 for experimenting with current limit, sine magnitude and

load angle

9.

Pressing SW1 again turns off the motor.
