Drive-Side Error Codes
Drive-side error codes appear on the drive keypad. Faults on page 35 lists causes of the errors and possible
corrective actions. Refer to the drive Technical Manual for additional error codes that can appear on the drive
keypad.
■
Faults
Both bUS [Option Communication Error] and EF0 [Option Card External Fault] can appear as a fault. When a
fault occurs, the keypad ALM LED stays lit. The ALM LED also illuminates. When an alarm occurs, the ALM
LED flashes.
If communication stops while the drive is running, answer these questions to help fix the problem:
• Is the communication line properly connected to the option? Is it loose?
• Is the CC-Link communication cable properly connected to the option?
• Is the PLC program working? Is the controller/PLC CPU stopped?
• Did a momentary power loss interrupt communications?
Code Name Causes Possible Solutions
bUS Option Communication Error
The drive did not receive a signal from the
controller.
The communications cable wiring is incorrect.
• Check for wiring errors.
• Correct the wiring.
An existing short circuit or communications
disconnection Check disconnected cables and short circuits and repair as needed
