(In the panel window, the three digits after “E” indicate an error number.)
Error No. Error name Description, action, etc.
C79 Pole sense operation error Operation is disabled in the pole sense mode.
C7A Servo unsupported function error An attempt was made to use an unsupported function. C7B Odd-pulse slide error Internal servo calculation error
C7C Odd-pulse processing logic error Internal servo calculation error C7D Packet pulse shortage error Internal servo calculation error
C7E Quadratic equation solution error An error was detected while calculating a quadratic equation solution.
C7F No valid specified axis error No valid axes are specified.
C80 Servo-packet calculation logic error Internal servo calculation error
If the controller is of absolute encoder specification and the system has just been moved or “Error No. C74, Actual-position soft limit over error” has also generated, the controller may be experiencing a servo-packet calculation overflow caused by abnormal current position resulting from an unsuccessful absolute reset. Perform an absolute reset again by following the operation manual. (Simply selecting “Encoder error reset” on the absolute reset screen will not allow the controller to recognize the correct position. Always perform an absolute reset by strictly following the specified procedure.)
C81 Operation-amount logic during servo ON Servo processing logic error C82 Servo direct command type error Servo processing logic error C83 Servo calculation method type error The servo calculation method type is invalid. C84 In-use axis servo OFF error The servo of an axis currently in use (being processed) was turned off. C85 Non-installed driver error Driver is not installed for the applicable axis. C86 Driver servo ready OFF error The ready signal for the driver of the applicable axis is OFF. C87 SEL unsupported function error An attempt was made to use a function not supported by SEL. C88 Speed specification error The specified speed is invalid. C89 Acceleration/deceleration specification error The specified acceleration/deceleration is invalid.
C8B Circle/arc calculation logic error The arc calculation logic is invalid.
C8D Circle/arc calculation error Position data that cannot be used in arc movement was specified. Check the
position data.
C8E Point deletion error during command execution The final point data was deleted while continuous point movement was being
calculated.
C8F Axis operation type error The axis operation type is invalid. Check “Axis-specific parameter No. 1, Axis
operation type” and perform operation appropriate for the operation type specified.
