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. 
 
[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.)
