11 TROUBLESHOOTING
(b) At operation start or in operation
The errors are detected at operation start or in operation such as OPR
control, positioning control and JOG operation.
If this error occurs at interpolation operation, the error number is stored in
both the reference axis and interpolation axis.
Release the errors by error reset after eliminating the error cause.
(3) Interface errors (Error code: 1900 to 1999)
The interface errors occur when the interface with hardware or CPU such as the
errors at FLASH ROM writing or PLC CPU failure is abnormal.
The interface error is detected as the error for Axis 1.
Execute the error reset for Axis 1 after eliminating the error cause.
If the other errors occur at interface error occurrence, the error code is updated.
(4) Servo errors (Error code: 2000 to 2099)
The servo errors occur when the hardware such as servo amplifier and
servomotor, or the servo parameter are abnormal.
The axis stops by servo OFF at error occurrence.
Execute the error reset after eliminating the error cause for the errors that can be
execute the axis error reset by the controller.
Execute the power cycle of the servo amplifier or system after eliminating the
error cause for the errors that cannot be executed the axis error reset by the
controller.
Refer to the Servo Amplifier Instruction Manual for details of the servo errors.
If the other errors occur at servo error occurrence, the error code is updated.
POINT
Start of positioning, OPR or manual control cannot be executed for the axis in
operation error occurrence. Start after reset errors.
