(5) Wiring method
Loosen the terminal screw and insert the cable into the terminal.
Screw Size: M3 Tightening Torque: 0.5N·m to 0.6N·m
2
Cable size: 0.3mm to 0.75mm
Screwdriver:Small flat-blade screwdriver (Edge thickness: 0.4mm/
Edge width: 2.5mm)
CAUTION
Undertightening can cause cable disconnection or malfunction.
Overtightening can cause a short circuit or malfunction due to
damage to the screw or unit.
16
Select one e.g. output frequency from
monitor items.
*2
The output signal is proportional to the
magnitude of the corresponding
monitoring item.
With the PU connector, communication can be made through RS-485.
