Troubleshooting/Diagnostics
This chapter details troubleshooting and diagnostics information fro the FlexPak 3000
drive.
The OIM also provides fault and alarm detection. See the OIM instruction manual
(D2-3344) for information on the faults and alarms and possible corrective actions.
4.1 Check for Wiring Errors
Wiring errors and loose or grounded wiring are common problems that can inhibit
operation of a drive. Verify that the wiring has been correctly installed and that the
drive is free of loose terminations and grounded conductors.
4.2 Verify AC Line and Power Input
Verify that the applied AC power is correct for the specific drive. If an isolation
transformer has been installed on the incoming AC power lines, verify its output
voltage and that it has been properly connected. Verify that the AC line fuses have
been correctly sized. The AC and DC power conductors should have been sized per
the National Electric Code (NEC) or Canadian Electric Code (CEC).
