10. Variable Speed Operation
(Variable Speed Pulse Output)-PLSV Instruction
The built-in positioning function uses the variable speed pulse output (PLSV) instruction equipped with the
rotation direction designation function to perform variable speed operation. If an FX
later or FX PLC is used, this instruction can change the speed using the acceleration/deceleration speed.
