Note The pulse output PV is reset to 0 just before
The following example shows the number of
pulses setting = −100.
Pulse output PV range:
80000000 to 7FFFFFFF hex
Number of pulses setting range:

The following table shows the pulse output operation for the four possible
combinations of the coordinate systems (absolute or relative) and the pulse
specifications (absolute or relative) made when PULS(886) or PLS2(887) is
executed.
