Output
24Vdc power output, by changing SW1 to
SINK or SOURCE side.
24Vdc-100mA
Input
This terminal can be used as a common
terminal when an external power supply
is used by changing SW1 to PLC side.
-
+SU
Input
DC power input terminal for operating the
control circuit. Connect a control power
backup device (option or 24Vdc power
supply) between +SU and CC.
Voltage:
24Vdc±10%
Current:
1A or more
Output
It is used with STO for safety function.
+SU and STO terminals are short-
circuited by metal bar and the inverter is
put into a standby state at default setting.
When the circuit between them is
opened, the motor is coasting stop.
-
STO
Note 2)
Input
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
used for inter lock.
This terminal is not a multifunction
programmable input terminal.
It is a terminal with the safety function
that complies with SIL II of the safety
standard IEC61508.
