During positioning control, the control can be interrupted during continuous positioning
control and continuous path control (continuous operation interrupt function). When
"continuous operation interruption" is execution, the control will stop when the
operation of the positioning data being executed ends. To execute continuous
operation interruption, set "1: Continuous operation interrupt request" for "
Interrupt request during continuous operation".

[2] Restrictions
(1) When the "continuous operation interrupt request" is executed, the positioning
will end.
Thus, after stopping, the operation cannot be "restarted".
Cd.6
When " Restart command" is issued, a warning "Restart not possible"
(warning code: 104) will occur.
(2) Even if the stop command is turned ON after executing the "continuous
operation interrupt request", the "continuous operation interrupt request"
cannot be canceled.
Thus, if "restart" is executed after stopping by turning the stop command ON,
the operation will stop when the positioning data No. where "continuous
operation interrupt request" was executed is completed.
