Change in Logic of interrupt input Signal (DVIT Instruction)

Turn "Interrupt signal logic reverse" flag ON or OFF to specify the logic of the interrupt input signal of each
interrupt positioning (DVIT) instruction.

Caution:
If a user interruption command device (M8360 to M8463) is specified in the interrupt input signal, the logic of
the user interruption command device cannot be specified. This is because turning on the user interruption
command device will turn on the interrupt input signal.

Acceleration/Deceleration by PLSV Instruction

Using the FX
3U
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 the 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 the operation. This means that acceleration/
deceleration cannot be specified for each pulse output destination device.
