*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 NO output terminal in
source logic mode, short the P24 and
OUT terminals.
*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 200V and 400V models.
*4: When VIA or VIB terminal is used as logic
input terminal, refer to section 7.2.1.
*1: Set the slide switch SW1 to source side.
Refer to page B-11,12 for details.
Default setting is PLC side.
*6: When STO terminal is used as compliance with
safety standards, refer to section 9.3.
