Function Description
P10V power supply for external unit, maximum output
current: 10mA
Generally, it provides power supply to external potentiometer
with resistance range of 1kΩ.
～
5kΩ.
P24V power supply to external unit, generally, it
provides power supply to S/Y terminals and external sensors.
Maximum output current: 100mA
Connect to +24V by default when S1

4.Y4 is limited by F5-00 “HY function enable”. As high-
speed pulse output, the maximum
frequency is 1000 kHz. When
output as open collector, the specification is the same as Y3.
5.It’s disconnected by default at the factory. If you need
to connect, you can short-circuit YC and COM by yourself.
