Use Pulse Output Function (Constant Pulse
Output)
Overview
Sending pulse output in direction control mode. Turn ON Enable input
at R4.0 and Start input. Pulse output starts at R2.8 and R2.9 (PLS0).
Output pulses are feedback to high-speed counter inside the unit. If a
pre-set value is reached, pulse stops.

Pulse
frequency
Certain number of pulses is sent out when Start
signal is ON.
• When the number of output pulses is extremely small,
pulse may not stop at the pre-set value due to internal
processing (scan time) delay.
• When pulse output is internally connected to counter, the
input mode of counter is automatically configured to the
pulse output. Be careful because previously configured
counter input mode is ignored.
• Within the internal connection, counter and pulse output
are fixed at the corresponding CH.
