14.5 List of Error Codes
Error details and causes
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.
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 sudden stop
selection (stop group 3) in the detailed parameter 2
when the current feed 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 current feed value is outside the software
stroke limit range.
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.
The new current address is outside the ranges of 0 to
359.99999, where the control unit is set to "degree".
[Operation status at error occurrence]
Current value is not changed.
Interpolation is started during the operation of the
interpolation axis.
[Operation status at error occurrence]
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.)
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/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.)
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/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.)
Remedy
At operation start: Set the current feed 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 current feed 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.
