2.3.2 Control circuit terminals

The control circuit terminal board is common to all equipment.
⇒ How to set input terminal function, refer to section 7.
Terminal
Input/

Shorting across F-CC causes forward
F
Input
rotation; open causes deceleration stop.
(Across ST-CC is short state.)
Shorting across R-CC causes reverse
R
Input
rotation; open causes deceleration stop.
(Across ST-CC is short state.)
The motor is on standby if ST and CC are
connected. It coasts to a stop if this
ST
Input
connection is broken. This terminal can be
used for interlocking.
Shorting and then opening RES-CC
cancels the status held by an inverter
RES
Input
protective function. When the inverter is
operating normally, shorting and then
opening RES-CC produces no effect.
Shorting across S1-CC causes preset
S1
Input
speed operation.
Shorting across S2-CC causes preset
S2
Input
speed operation.
Shorting across S3-CC causes preset
S3
Input
speed operation.
SW3: When SW3 is in the S4 position, S4

Input
and CC are shorted and preset speed
operation is selected.

If SW1 is turned to the PLC position, this

terminal can be used as a common terminal
when an external power supply is used.
