(3) Operation

Travels for the interrupt positioning travel distance ([Pr. PT30] and [Pr. PT31]) starting from the position

where MSD (Mark detection) is turned on. The operation after a stop complies with the operation mode

and the operation pattern.

(4) Timing chart

Note.

Deceleration time constant of the point table at the time of start is applied for the point table method, and

deceleration time constant set by the program in execution is applied for the program method.

The movement other than above is as follows:

(a) When the interrupt positioning travel distance is smaller than the travel distance required for the

deceleration, the actual deceleration time constant will be shorter than the set time constant.
