Deceleration start flag function
Deceleration start flag function turns on a flag when the speed is switched from the constant speed or acceleration to the
deceleration during the position control whose operation pattern is Positioning complete. The flag can be used as a signal to
start the operation to be performed by another device at every completion of the position control or to perform preparatory
operation for the next position control.
Control details
When the deceleration stop is started in the position control whose operation pattern is Positioning complete, 1 is stored in
[Md.48] Deceleration start flag. When the next operation starts or the manual pulse generator operation is enabled after the
stop, 0 is stored.

For the block start, this function is valid for only the position control whose operation pattern is Positioning complete at the
point to which [Da.11] Shape is set to End.
The following table shows the operation of Deceleration start flag in the case when the following block start data and
positioning data are used.
