Inverter internal circuits
F Input
Shorting across F-CC causes
forward rotation; open causes slow-
down and stop. (When ST is always
ON)
R Input
Shorting across R-CC causes
reverse rotation; open causes slow-
down and stop. (When ST is always
ON)
RES Input
This inverter protective function is
disabled if RES are CC is connected.
Shorting RES and CC has no effect
when the inverter is in a normal
condition.
S1 Input
Shorting across S1-CC causes
preset speed operation.
S2 Input
Shorting across S2-CC causes
preset speed operation.
S3 Input
Multifunction programmable contact input
Shorting across S3-CC causes
preset speed operation.

current: 10mA)
VIA Input
Multifunction programmable analog input.
Factory default setting: 0~10Vdc and
0~60Hz (0~50Hz) frequency input.
The function can be changed to
4~20mAdc (0~20mA) current input by
flipping the dip switch to the I position.
By changing parameter setting, this
terminal can also be used as a
multifunction programmable contact input
terminal. When using the sink logic, be
sure to insert a resistor between P24-VIA
(4.7 kΩ―1/2 W). Also move the VIA dip
switch to the V position.
