Allen-Bradley 1305-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

When the A-B 1305 drives encounter a fault, an LED is illuminated. Refer to Figure 46 and Figure 45, respectively. These LEDs are viewed with the front cover removed. To view the specific fault description, the HIM (parameter unit) must be installed. Refer to HIM installation and operation.

Once the HIM is installed, the current fault condition is displayed as shown below with the corresponding fault code. Cross reference the number in Table 45 for fault identification and possible corrective action.

In addition, A-B 1305 fault codes are stored in a fault buffer with the capability to store up to four fault codes. If more than four 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 HIM as shown below. Refer to HIM installation and operation

.

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.
