Error name Error details and causes
Overcarrying movement The movement amount which exceeds the detailed
amount overflow in manual parameter 2 "Manual pulse generator speed limit
pulse generator value" is generated continuously and the "Amount of
the manual pulser driving carrying over movement"
exceeds tolerance (-2147483648 to 2147483647).
[Operation status at error occurrence]
The system decelerates to a stop.
Error before simultaneous <When multiple axes are started and controlled
start simultaneously>
• The partner axis for simultaneous start is BUSY.
• The partner axis for simultaneous start is not
present.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The operation is terminated.
Error before simultaneous <When multiple axes are started and controlled
start simultaneously>
• The same axis No. is set to multiple simultaneous
start axes.
• The own axis No. is set to a simultaneous start axis.
• The number of simultaneous start axes is outside the
setting range of 2 to 4.
• The "Simultaneous starting axis start data No." of the
start axis is 0 or is outside the setting range.
• The "Simultaneous starting axis start data No." of the
start axis and the partner axis for simultaneous start
is 0 or is outside the setting range.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The operation is terminated.
Software stroke limit + The command position exceeds the upper 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.
• In the analysis of new current value: Current value is
not changed.
• 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 upper limit of the
software stroke limit.
[Operation status at error occurrence]
In the analysis of new current value: Current value is
not changed.

Remedy
• Adjust input pulses so as not to occur the
movement amount, which exceeds the
detailed parameter 2 "Manual pulse generator
speed limit value", continuously.
• Change the detailed parameter 2 "Manual
pulse generator speed limit mode" to a value
other than "2: Output over value of speed limit
later".
Normalize the simultaneous start axis.
Normalize the simultaneous starting own axis
start data No. and the simultaneous starting axis
start data No. (1 to 3).
• 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.
