This terminal can be used as a common
Input terminal when an external power supply
is used by changing SW1 to PLC side.
DC power input terminal for operating the
control circuit. Connect a control power

backup device (option) between +SU and
+SU CC.
It is used with STO for safety function.
Output +SU and STO terminals are short-
circuited by metal bar at default setting.
When +SU and STO are short-circuited,
the inverter is put into a standby state.
(Default setting) And when the circuit
between them is opened, the motor is
coasting stop. These terminals can be

It is a terminal with the safety function
that complies with SIL II of the safety
standard IEC61508.
Note2) When STO terminal is used as the safety function, refer to section 9.3.
