10.3.2 Operation with Acceleration/Deceleration (M8338 = ON)

If the output pulse frequency
acceleration/deceleration (M8338) ON, the variable speed pulse output
(PLSV) instruction will accelerate or decelerate to the changed output.
If a FX PLC below Ver.2.20 is used, operation will be performed without acceleration/deceleration.
