12 Fault Diagnosis and Possible Solutions
◆
CANopen Option Card Error Codes
Refer to Table 6 for a list of possible error codes.
◆
Drive-Side Error Codes
Drive-side error codes appear on the drive’s digital operator. Causes of the errors and corrective actions are listed in Table 8 and Table 9 . For
additional error codes, refer to the technical manual for the drive.
bUS (CANopen Option Communication Error) and EF0 (External Fault Input from the CANopen Option) may appear as an alarm or a fault. If they
occur as an alarm, the "ALM" LED on the drive digital operator will blink and the alarm code will flash in the display. When they occur as a fault,
the “ALM” LED will light and the display will show the fault code.
If communication stops while the drive is running, check the following items:
• Is the CANopen Option properly installed?
• Is the communication line properly connected to the CANopen Option? Is it loose?
• Is the controller program working? Has the controller CPU stopped?
• Did a momentary power loss interrupt communications?
■ Faults
Table 8 lists possible faults when using a communication option board. The drive’s fault contact will close if one of these faults occurs.

Digital Operator Display Fault Name
bUS
CANopen Option Communication Error
After establishing initial communication, the connection was lost.
Only detected when the run command or frequency reference is assigned to the option (b1-01=3 or b1-02=3).
Cause Possible Solution
Master controller (PLC) has stopped communicating. Check for faulty wiring.
⇒ Correct any wiring problems.
Communication cable is not connected properly.
A data error occurred due to noise.
Check the various options available to minimize the effects of noise.
⇒ Take steps to counteract noise in the control circuit wiring, main circuit lines, and ground wiring.
⇒ If a magnetic contactor is identified as a source of noise, install a surge absorber to the contactor coil.
⇒ Make sure the cable used fulfills the CANopen requirements. Ground the shield on the controller side and on the
CANopen Option side.
CANopen Option is damaged. ⇒ If there are no problems with the wiring and the error continues to occur, replace the CANopen Option.
Digital Operator Display Fault Name
EF0
External Fault Input from CANopen Option
The alarm function for an external device has been triggered.
Cause Possible Solution
An external fault is being sent from the upper controller (PLC).
⇒ Remove the cause of the external fault.
⇒ Reset the external fault input from the upper controller (PLC) device.
Problem with the upper controller (PLC) program. ⇒ Check the program used by the upper controller (PLC) and make the appropriate corrections.
Digital Operator Display Fault Name
oFA00
Option Card Fault at Connector CN5-A
The drive dose not support the option board plugged into port CN5-A.
Cause Possible Solution
Non-compatible option connected to the drive.
⇒ Check the drive option board compatibility. Replace the option card if the fault persists even though the drive should
support it.
Digital Operator Display Fault Name
oFA01
Option Card Fault at Connector CN5-A
Option card is not properly connected.
Cause Possible Solution
Problem with the connectors between the drive and CANopen
Option.
⇒ Turn the power off and check the connectors between the drive and CANopen Option.
