1 PRODUCT OUTLINE
Reference
Provide the emergency stop circuits external to the servo system to prevent cases
where danger may result from abnormal operation of the overall in the event of a
power supply fault or servo system failure.
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 restart disable
warning (warning code: 104) will be applied, and the restart command will be
ignored.
[Example for incremental system]
(a) The restart operation when the axis 1 movement amount is 300, and the
axis 2 movement amount is 600 is shown below.

Reference
If the positioning start signal [Y10 to Y13]/external command signal is turned ON
while the "
Md.26
Axis operation status" is waiting 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.)
