Input
This terminal can be used as a common
terminal when an external power supply
is used by changing SW1 to PLC side.
-
Input
DC power input terminal for operating the
control circuit. Connect a control power
backup device (option) between +SU and
CC.
Voltage: 24Vdc±
10%
Current: 1A or
more
+SU
Output
It is used with STO for safety function.
+SU and STO terminals are short-
circuited by metal bar at default setting.
-
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.
Independently of
SW1
ON: DC17V or
more
OFF: Less than
DC12V
(OFF: Coast stop)
Note2) When STO terminal is used as the safety function, refer to section 9.3.
