Drive-Side Error Codes
Drive-side error codes appear on the drive keypad. This section lists causes of the errors and possible corrective
actions. Refer to the drive Technical Manual for additional error codes that may 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. When an alarm occurs, the ALM LED flashes.
If communication stops while the drive is running, use these questions as a guide to help remove the fault:
•
Is the communication line properly connected to the option? Is it loose?
•
Is the option properly installed?
•
Is the host controller program working? Is the controller/host controller 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
A data error occurred due to electric interference
•
Prevent noise in the control circuit, main circuit, and ground
wiring.
• If you identify a magnetic contactor as a source of noise,
install a surge absorber to the contactor coil.
•
Use only recommended cables or other shielded line. Ground
the shield on the controller side or the drive input power side.
• Separate all communication wiring from drive power lines.
Install an EMC noise filter to the drive power supply input.
•
Decrease the effects of electrical interference from the host
controller.
Option is damaged If there are no problems with the wiring and the error continues to
occur, replace the option.
Connection Time-out Check if the CPU of the controller is not stopped.
Duplicate IP Address found on network Change to a different IP address. If F7-13 = 0 [Address Mode at
Startup = Static] , change parameters F7-01 to F7-04 [IP Address
1 to 4] .
EF0 Option Card External Fault
The option received an external fault from the
controller. 1. Find the device that caused the external fault and remove the
cause.
2. Clear the external fault input from the controller.
A programming error occurred on the controller
side. Examine the operation of the controller program.
oFA00 Option Not Compatible with Port The option connected to connector CN5-A is not
compatible. Connect the option to the correct connector.
•
Use connector CN5-A when you connect the option.
To use other options, refer to those option manuals.
Invalid DIP switch S1 setting. Set the option DIP switch S1 as shown in page 11 . Monitor, U4-
75 [Communication OPT Protocol] will display the DIP switch
S1 setting.
