Error name Error details and causes
Software stroke limit - The command position exceeds the lower limit of the
software stroke limit.
[Operation status at error occurrence]
At operation start: The system does not operate.
In the analysis of new current value: Current value is
not changed.
During operation:
• The system stops immediately when the positioning
address during position control (including position
control in speed-position switching control or
position-speed switching control) is switched to the
data outside the software stroke limit range.
• During speed control (including speed control in
speed-position switching control or position-speed
switching control), the system stops at the setting
(normal deceleration stop only) of rapid stop
selection (stop group 3) in the detailed parameter 2
when the feed current value or machine feed value
during manual control is outside the software stroke
limit range.
At speed control mode/torque control mode/continuous
operation to torque control mode: The system switches
to the position control mode and stops immediately
when the feed current value is outside the software
stroke limit range.
Software stroke limit - The new current value exceeds the lower limit of the
software stroke limit.
[Operation status at error occurrence]
In the analysis of new current value: Current value is
not changed.
Outside new current value The new current address is outside the ranges of 0 to
range 359.99999, where the control unit is set to "degree".
[Operation status at error occurrence]
Current value is not changed.
Interpolation while Interpolation is started during the operation of the
interpolation axis BUSY interpolation axis.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops with the setting
(deceleration stop/rapid stop) of the detailed parameter
2 Rapid stop selection (stop group 3). (Note that the
deceleration stop only occurs during the manual pulse
generator operation.)
Unit group unmatched The reference and interpolation axis units are different
at the parameter "interpolation speed designation
method" setting of "composite speed".
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops with the setting
(deceleration stop/rapid stop) of the detailed parameter
2 Rapid stop selection (stop group 3). (Note that the
deceleration stop only occurs during the manual pulse
generator operation.)
Interpolation mode error For starting, a composite speed is designated in the
reference axis parameter "Interpolation speed
designation method" using the speed interpolation
control or 4-axis linear interpolation control.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops with the setting
(deceleration stop/rapid stop) of the detailed parameter
2 Rapid stop selection (stop group 3). (Note that the
deceleration stop only occurs during the manual pulse
generator operation.)

Remedy
At operation start: Set the feed current value
within the software stroke limit by the manual
control operation.
At speed control mode/torque control mode/
continuous operation to torque control mode:
Review the operation so that the feed current
value does not exceed the software stroke limit.
Set the new current value within the software
stroke limit.
Bring the new current value into the setting
range.
Correct the control method.
Correct the positioning data or change the
parameter "Unit setting" of the axis to be
interpolated.
Set the "Interpolation speed designation
method" correctly.
