7.3 Error List (MAIN application)
453
In the panel window, the error numbers follow E in the display.
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 occur if operation is performed
immediately after changing an encoder parameter,
performing an absolute encoder reset or resetting an
encoder error, without first executing a software reset or
reconnecting the power.
C71 Synchro slave-axis command error A command was issued to the synchro slave axis.
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.
* In the case of a SCARA specification, position data may
not exist for the applicable axis.
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-position 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 servo 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 the controller is of absolute-encoder specification and an
“Error No. C74, Actual-position soft limit over error” is also
present, an absolute reset may not have been executed
correctly and consequently a servo packet calculation
overflow occurred due to a current position error.
If this is the case, perform an absolute reset again by
following the procedure specified in the operation manual.
(Performing an “encoder error reset” operation in the
absolute reset window alone does not allow the controller
to recognize the current position correctly.
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.
