Control circuit terminals
Function
Shorting across F-CC or P24-F
causes forward rotation; open
causes deceleration stop.
(When Standby ST is always ON)
3 different functions can be
assigned.
Shorting across R-CC or P24-R
causes reverse rotation; open
causes deceleration stop.
(When Standby ST is always ON)
3 different functions can be
assigned.
This inverter protective function is
reset if RES-CC or P24-RES is
connected. Shorting RES-CC or
P24-RES has no effect when the
inverter is in a normal condition.
2 different functions can be
assigned.
Shorting across S1-CC or P24-S1
causes preset speed operation.
2 different functions can be
assigned.
Shorting across S2-CC or P24-S2
causes preset speed operation.
By changing parameter f146
setting, this terminal can also be
used as a pulse train input terminal.
Shorting across S3-CC or P24-S3
causes preset speed operation.
By changing slide switch SW2 and
parameter f147 setting, this
terminal can also be used as a PTC
input terminal.
