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
Shorting across RES-CC causes a
held reset when the inverter protector
function is operating. Note that when
the inverter is operating normally, it
will not operate even if there is a
short across RES-CC
S1
Input
Shorting across S1-CC causes
preset speed operation.
S2
Input
Shorting across S2-CC causes
preset speed operation.

External 24Vdc power input
When the source logic is used, a common
terminal is connected.

VIA
Input
Multifunction programmable analog input.
Factory default setting: 0~10Vdc and
0~60Hz frequency input.
The function can be changed to
4~20mAdc (0~20mA) current input by flip-
ping the slide switch to the I position.
By changing parameter setting, this termi-
nal can also be used as a multifunction
programmable contact input terminal.
When using the sink logic, be sure to in-
sert a resistor between P24-VIA (4.7
