AC/DC Drive Repair Process:
To begin the repair on an AC/DC drive a visual inspection is performed.
- Next meters and signature analysis devices are used to component test.
- Common failure parts such as capacitors, drive and output transistors, power supplies, SCR’s, and firing circuits are checked first.
- Common failure parts are tested and replaced as necessary
- Drive is then powered up
- While powered up the power supplies are checked as are the outputs for proper wave form
- A dummy load is applied to the drive and the output waveform is checked with an oscilloscope
- If proper output is seen the dummy load is removed and the drive is fully load tested with the proper motor and with a dynamometer
- It is scoped again for proper wave form
- Entire unit is cleaned and retested
