Variable Speed Operation

The positioning function uses the variable speed pulse output instruction equipped with the rotation direction designation
function to perform variable speed operation.
This instruction can change the speed using the acceleration/deceleration speed.
PLSV/DPLSV
This instruction outputs variable speed pulses with an assigned rotation direction output.
