Power Checks

TEST PROCEDURE CHECKLIST

1. Remove the DC bus fuse and replace it with a 30W, 500 ohm resistor.

2. Apply power to terminals L1, L2, & L3.

3. Check the DC bus voltage.

4. Check the 15V power supply.

5. Check the (-15V) power supply. (GPD515/G5 only)

6. Check the isolated 24V power supply.

7. Check the output voltage waveform.

8. Check the gate firing pulses (if necessary).

9. Remove the 500 ohm resistor, re-install the DC bus fuse.

10. Run the motor.

11. Check the output current waveform.

12. Check the control board inputs and outputs.

13. Check the PG pulses. (GPD515/G5 only)
