Function and Operation

The variable speed pulse output instruction changes the speed while using the rotation direction output.
The acceleration/deceleration function applies for the variable speed pulse output (PLSV) instruction, which
makes it possible to specify whether acceleration/deceleration will be used or not.
If an FX

If the output pulse frequency
(M8338) OFF, the variable speed pulse output (PLSV) instruction will change the output frequency without
using acceleration/deceleration.
