Allen-Bradley 160-Series AC Drives

Fault Display and Troubleshooting Information

This section provides information to guide users in understanding drive fault conditions and general troubleshooting procedures for Allen-Bradley drives. Included is a listing and description of the various drive faults with possible solutions, when applicable. For any questions regarding fault conditions, consult with the factory.

Each drive is equipped with a fault indicator light which illuminates when a fault condition exists.

Fault Code Identification

A-B 160

When a fault occurs, the fault indicator light will illuminate on the front cover of the A-B 160 drive, as shown in Figure 36. To view the fault type, the PKM or CopyCat Keypad must be installed. The A-B 160 fault number is located in parameter #07. Refer to PKM or CopyCat Keypad installation and operation. The PKM will flash the display when a fault is present as shown below (i.e., Fault Code 22). Cross reference the number in Table 34 for fault identification and possible corrective action.

In addition, A-B 160 Series C fault codes are stored in a fault buffer with the capability to store up to three fault codes. If more than three faults are identified, the least recent fault is deleted to make room for the additional fault. “Fault Buffer 0” is the most recent fault. The faults are viewed using a PKM as shown below. Refer to PKM installation and operation.

The fault parameters are identified as follows:

“Last Fault”

Clearing Faults

When a fault occurs, the cause must be corrected before the fault can be cleared. Resetting a fault will not correct the cause of the fault condition. After corrective action has been taken, simply cycling power to the drive will clear the fault.
