- 6.1 Test Equipment Needed To Troubleshoot
- 6.2 Verifying That DC Bus Capacitors Are Discharged
- Step 1. Turn off and lock out input power. Wait five minutes.
- Step 2. Verify that there is no voltage at the drive’s input power terminals.
- Step 3. Measure the DC bus potential with a voltmeter while standing on a non-conductive surface and wearing insulated gloves (1...
- Step 4. Once the drive has been serviced, reapply input power.

- Figure 6.2 - DC Bus Voltage Terminals (500 Amp and 643 Amp Drives)
- 6.3 Checking the Power Modules and Motor with Input Power Off
- Step 1. Turn off and lock out input power. Wait five minutes.
- Step 2. Verify that there is no voltage at the drive’s input power terminals.
- Step 3. Check the DC bus potential with a voltmeter as described in section 6.2 to ensure that the DC bus capacitors are discharged.
- Step 4. Disconnect the motor from the drive.
- Step 5. Check all AC line and DC bus fuses.
- Step 6. If a fuse is open, use a multimeter to check the input diodes and output IGBTs. See table 6.1.
- Step 7. Check motor impedance.
- Step 8. Reconnect the motor to the drive.
- Step 9. Reapply input power.
