Electrical specifications
F Input
Multifunction programmable contact input
Shorting across F-CC causes forward
rotation; open causes deceleration
stop. (Across ST-CC is short state.)
Shorting across F-P24/PLC causes
forward rotation; open causes
deceleration stop.
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.
R Input
Shorting across R-CC causes reverse
rotation; open causes deceleration
stop. (Across ST-CC is short state.)
Shorting across R-P24/PLC causes
reverse rotation; open causes
deceleration stop.
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.
Shorting and then opening RES-
P24/PLC cancels the status held by an
inverter protective function. When the
inverter is operating normally, shorting
and then opening RES-P24/PLC
produces no effect.
S1 Input
Shorting across S1-CC causes preset
speed operation.
Shorting across S1-P24/PLC causes
preset speed operation.
S2 Input
Shorting across S2-CC causes preset
speed operation.
Shorting across S2-P24/PLC causes
preset speed operation.
S3 Input
Shorting across S3-CC causes preset
speed operation.
Shorting across S3-P24/PLC causes
preset speed operation.
RR/S4 Input
SW3: When SW3 is in the S4 position,
S4 and CC are shorted and preset
speed operation is selected.

S4 and P24/PLC are shorted and preset
