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)
Check box when completed
