Acceleration/Deceleration by PLSV Instruction

Using an FX
3UC
(M8338) is turned on, the variable speed pulse output (PLSV) instruction will be activated to accelerate/
decelerate the operation.
This means that if the command value of the output pulse frequency is changed, the operation will be
accelerated or decelerated to the changed output pulse frequency depending on the specified acceleration/
deceleration time.
Bias speed
Initial value: 0 Hz
Caution:
• To enable acceleration/deceleration, turn on M8338 first, and then activate the variable speed pulse output
(PLSV) instruction.
• If acceleration/deceleration is enabled, the variable speed pulse output (PLSV) instructions of all the pulse
output destination devices will accelerate/decelerate with the same time. This means that acceleration/
deceleration cannot be specified separately for each pulse output destination device.
