1.2.4 Outline for restarting
When a stop cause has occurred during operation with position control causing the
axis to stop, positioning to the end point of the positioning data can be restarted from
the stopped position by using the "
Cd.6
Restart command
".
If issued during a continuous positioning or continuous path control operation, the
restart command will cause the positioning to be re-executed using the current position
(pointed by the positioning data No. associated with the moment when the movement
was interrupted) as the start point.
When "
Cd.6
Restart command
" is ON
(1) If the "
Md.26
Axis operation status
" is stopped, positioning to the end point of the
positioning data will be restarted from the stopped position regardless of the
absolute system or incremental system.
(2) When "
Md.26
Axis operation status
" is not stopped, the warning "Restart not
possible" (warning code: 104) will be applied, and the restart command will be
ignored.
(a) The restart operation when the axis 1 movement amount is 300 and the
axis 2 movement amount is 600 is shown below.

REMARK
If the positioning start signal/external command signal is turned ON while the
"
Md.26
Axis operation status
" is standby or stopped, positioning will be restarted from
the start of the positioning start data regardless of the absolute system or
incremental system. ( : When the external command signal is set to "External
positioning start") (Same as normal positioning.)
[Example for incremental system]
(a) The positioning start operation, which stops the positioning control while
executing that the axis 1 movement amount is 300 and the axis 2
movement amount is 600, is shown below.
