Error
The arc radius exceeds 536870912.
A "0" is set in the repeating times of the
control method "LOOP".
The setting value of ABS direction in the
unit of degree is as follows.
• Set outside the setting range.
• A figure other than "0" is set when the
software stroke limit is valid.
• When executing operation setting at OPR
incomplete, positioning was started at
OPR request ON.
• When executing operation setting at OPR
incomplete, control mode switching was
executed at OPR request ON.
Switching to the continuous operation to
torque control mode is requested to a servo
amplifier which does not support the
continuous operation to torque control.
When setting the control mode auto-shift
switching selection, the control mode auto-
shift switching parameter is outside the
range.
In the CPU module parameter "Output at
error stop", the setting for the Simple
Motion module is "Hold".
Data is not written to the flash ROM.
While data is written to the flash ROM, the
power is turned OFF.

Operation status at error occurrence
At start : The system does not
operate.
During operation : The system stops
immediately.
The operation is terminated.
At start : The system does not
operate.
During operation : The system decelerates to
a stop.
(Note that, in the continuous
positioning control and
continuous path control, the
system continues operating
with the setting set at the
time of start even if the
setting is changed during
the operation.)
At start : The system does not
operate.
At control mode switching: The mode does
not change.
During positioning control:
The system stops with the
setting of the detailed
parameter 2 sudden stop
selection (stop group 3).
During speed control mode:
The mode is switched to
position control mode, and
the system stops
immediately.
At start : The system does not
operate.
During operation : The system stops with the
setting (deceleration
stop/sudden stop) of the
detailed parameter 2
sudden stop selection
(stop group 3).
(Note that the deceleration
stop only occurs during the
manual pulse generator
operation.)
At start: The system does not operate.
