Fault Enable Group
Low DC Bus Fault Enable
This parameter’s default setting is enabled. When enabled, the drive will detect a low DC bus at 60 Vdc and will log a
Low DC Bus Fault if a power down is not completed after the low DC bus is detected. Clearing this check box will disable
the Low DC Bus Voltage Fault. This will allow the drive to operate at a DC bus voltage below 60 Vdc as long as the logic
power is supplied by the Logic Power Supply.
Encoder State Fault Enable
This parameter’s default setting is enabled. When enabled, the drive will detect encoder state faults. Refer to Fault
Codes in the Diagnostic and Troubleshooting section of this manual. The drive will not detect Encoder State faults when
the fault is disabled. Disabling encoder faults is necessary for some types of programmable encoders when the state
transitions are not always deterministic.
Commutation Hardware Fault Enable
When this check box is selected, faults occurring from the commutation tracks U, V, and W will be recognized as "E"
faults in the drive. When this check box is clear, no fault will occur due to the commutation tracks. This functionality can
be useful to diagnose the nature of the "E" fault. If the check box is clear and "E" faults are still occurring, then the
encoder lines
(A, A/, B, B/, Z, Z/) are the most likely source of the "E" fault.
