Input
PLC When the source logic is used, a common
(common)
terminal is connected.
Common to Control circuit's equipotential terminal (3
CC
Input/output terminals)
P Output Analog input setting power output
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.
VIA Input
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
kΩ
to the V position.
Function
Shorting across F-CC causes
forward rotation; open causes slow-
down and stop. (When ST is always
ON)
Shorting across R-CC causes
reverse rotation; open causes slow-
down and stop. (When ST is always
ON)
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
Shorting across S1-CC causes
preset speed operation.
Shorting across S2-CC causes
preset speed operation.
Shorting across S3-CC causes
preset speed operation.
