Fault Codes
Chapter 10
10-2
Auxiliary Fault
Freq P R
The auxiliary input interlock is open. The auxiliary interlock is:
Jumper 9-10 of J9 on the Main Control Board if interface option L1, L2,
L3 is not installed.
Terminal 28 of TB3 if interface option L1, L2 L3 is installed.
Power Loss
Freq P R
Occurs only if Parameter 40 is set to 0 and input power is interrupted for
0.2 seconds. Monitor the incoming AC line for low voltage or line power
interruption.
Bus Undervoltage
Freq P R
Occurs when the DC bus drops below:
388V DC for drives with Base Driver/Power Supply Board Firmware
Versions 1.11, 1.13, 1.14 or 3.01.
456V DC for drives with Base Driver/Power Supply Board Firmware
Versions 1.01.
Monitor the incoming AC line for low voltage or line power interruptions.
Bus Overvoltage
Freq P R
Occurs when the DC bus rises above:
810V DC for drive ratings B003-B200.
975V DC for drive ratings C003-C200.
May be caused by high line voltage or excessive regeneration from the
motor. Monitor the AC line for high line voltage or transient conditions. If
caused by motor regeneration, extended decel time or dynamic braking
may be required.
