Grounding terminal for connecting inverter. There are 3 terminals in total. 2 terminals in
the terminal board, 1 terminal in the cooling fin.
240V class: single-phase 200 to 240V-50/60Hz
three-phase 200 to 240V-50/60Hz
500V class: three-phase 380 to 500V-50/60Hz
600V class: three-phase 525 to 600V-50/60Hz
* Single-phase input: R/L1 and S/L2 terminals
Connect to a (three-phase induction) motor.
Connect to braking resistors.
Change parameters
This is a negative potential terminal in the internal DC main circuit. DC common power
can be input across the PA terminals (positive potential).
Terminals for connecting a DC reactor (DCL: optional external device). Shorted by a
short bar when shipped from the factory. Before installing DCL, remove the short bar.
Control circuit terminals
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)
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.
Shorting across S1-CC causes
preset speed operation.
Shorting across S2-CC causes
preset speed operation.
Shorting across S3-CC causes
preset speed operation.
External 24Vdc power input
When the source logic is used, a common
terminal is connected.
