(In the panel window, the three digits after “E” indicate an error number.)
Error No. Error name Description, action, etc.
C70 Absolute coordinate non-confirmation error Absolute coordinates have not been confirmed. The power must be reconnected.
This error may also generate when the actuator is operated after changing an
encoder parameter, executing an absolute reset or resetting an encoder error,
without executing a software reset or reconnecting the power first.
C71 Synchro slave-axis command error A command was issued to the synchro slave axis. Cartesian axis only.
C72 Overrun error The overrun sensor was actuated.
C73 Target-locus soft limit over error The target position or movement locus exceeds a soft limit.
* If this error occurred on a SCARA axis, the axis may not have position data.
C74 Actual-position soft limit over error The actual position exceeds a soft limit by the “soft limit/actual position margin” or
more.
C75 Motion-data-packet generation logic error The motion-data-packet generation logic is invalid.
C76 Movement-point count over error Too many packets are generated simultaneously.
C77 Handling-packet overflow error The servo handling packets overflowed.
C78 Motion-data-packet overflow error The motion data packets overflowed.
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, with an absolute encoder specification, this error occurred after relocating the
system or when an “Error No. C74, Actual-position soft limit over error” is also
present, a servo packet calculation overflow may have occurred due to an invalid
current position because an absolute reset was not executed correctly. Execute an
absolute reset again by following the procedure in the operation manual.
(“Resetting an encoder error” in the absolute reset window alone will not cause the
controller to recognize the current position correctly. Always execute an absolute
reset by 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.
