2.3.2 Control circuit terminals
The control circuit terminal board is common to all equipment.
Shorting bar between ST-CC (VFAS1- -WN)
⇒ How to set input terminal function, refer to section 7.

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

SW3: When SW3 is in the S4 position, S4
and CC are shorted and preset speed
operation is selected.
Voltage free contact
input
24Vdc-5mA or less
*Sink/source selectable
with SW1
Sink input
ON:Less than DC10V
OFF:DC16V or more
Source input
ON:DC11V or more
OFF:Less than DC5V
Note:
Even when an
external power supply
is used (in sink logic
mode, i.e., when SINK
(PLC) is selected),
connect the reference
potential-side (0V
side) cable from the
power supply to the
CC terminal.
Output
24Vdc power output (when SW1 is in any
position other than PLC)
24V internal output terminal
24Vdc-200mA

Input
If SW1 is turned to the PLC position, this
terminal can be used as a common terminal
when an external power supply is used.

Common
to input/

Digital signal equipotential (0V) terminal for the
control circuit and equipotential (0V) terminal
for an optional control power supply backup.
-
Lan current signal.
Choose low current
contacts to avoid
poor attaching.
