(In the panel window, the three digits after “E” indicate an error number.)
Error No. Error name Description, action, etc.
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.
C90 Spline calculation logic error The spline processing logic is invalid.
C91 Push-motion axis multiple specification error Two or more push-motion axes were specified.
C92 Push-motion approach distance/speed specification error The specified push-motion approach distance/speed is invalid.
C93 System output operation error The user attempted a system output operation (through the port specified by I/O
parameter for output function selection or the zone output port specified by axis-
specific parameter).
C94 PIO program number error The program number specified by the PIO is outside the range of 1 to 64.
C95 AUTO program number error The setting of “Other parameter No. 1, Auto-start program number” is invalid.
C96 Start error from operation-abort program (This error should not occur now that the specification has been changed.)
C97 Program number error for I/O processing program at
operation/program abort
The setting of “Other parameter No. 2, I/O processing program number at
operation/program abort” is invalid.
C98 Program number error for I/O processing program at operation
pause
The setting of “Other parameter No. 3, I/O processing program number at all
operation pause” is invalid.
C99 Home sensor non-detection error The home sensor cannot be detected. Check the wiring and sensor.
C9A Creep sensor non-detection error The creep sensor cannot be detected. Check the wiring and sensor.
C9B Phase Z non-detection error Phase Z cannot be detected. Check the wiring and encoder.
C9C Defective phase-Z position error The phase-Z position is defective. Normal wear and tear of the mechanical ends
and home sensor may also be a reason. Readjustment is necessary.
C9D Card parameter write error Error writing card parameters
C9E Servo calculation overflow error Internal servo calculation error
CA1 Abnormal absolute-data backup battery voltage (Driver analysis) Check the connection of the absolute-data backup battery/replace the battery and/or
check the encoder cable connection, and then perform an absolute reset.
CA2 Abnormal absolute-data backup battery voltage (Main analysis) Check the connection of the absolute-data backup battery/replace the battery and/or
check the encoder cable connection, and then perform an absolute reset.
CA3 Slave setting data out-of-range error The data set to the slave is outside the allowable range.
CA4 Slave error response An error response was returned from the slave.
