supply
*1: Set the slide switch SW1 to sink side.
Refer to page B-11,12 for details.
Default setting is PLC side.
*2: The T/L3 terminal is not provided for
single-phase models.
Use the R/L1 and S/L2/N terminals as
input terminals.
*3: When using the OUT output terminal in
sink logic mode, short the NO and CC
terminals.
*4: When VIA or VIB terminal is used as logic
input terminal, refer to section 7.2.1.
*5: To supply control power from an external
power supply for backing up the control
power supplied from the inverter, an optional
control power backup device (CPS002Z) is
required. In such a case, the backup device
is used at the same time with the internal
power supply of the inverter.
The optional control power backup unit can
be used with both 240V and 500V models.
*6: When STO terminal is used as compliance with
safety standards, refer to section 9.3.
