The arrangements of power circuit terminals are different from each range.
Refer to section 1.3.3.1) for details.
2.3.2 Control circuit terminals
The control circuit terminal board is common to all equipment.
Regarding to the function and specification of each terminal, please refer to the following table.
Refer to section 1.3.3.3) about the arrangement of control circuit terminals.
 Control circuit terminals
Terminal Input /
symbol output
Shorting across F-CC causes
forward rotation; open causes slow-
F Input down and stop. (When Standby ST
is always ON)
3 different functions can be assigned.
Shorting across R-CC causes
reverse rotation; open causes slow-
R Input down and stop. (When Standby ST
is always ON)
3 different functions can be assigned.
Shorting across S1-CC causes
S1 Input preset speed operation.
2 different functions can be assigned.
Shorting across S2-CC causes
S2 Input preset speed operation.
2 different functions can be assigned.
24Vdc power output

P24
This terminal can be used as an external
Input 24Vdc input for logic input terminal by
changing parameter f127=200.
Common
Control circuit's equipotential terminal (2
CC to Input /
terminals)
output
Grounding terminal for connecting inverter.
There are 4 terminals in total. (1 terminal on upper side, 3 terminals on down side)
240V class: three-phase 200 to 240V-50/60Hz
single-phase 200 to 240V-50/60Hz
120V class: single-phase 100 to 120V-50/60Hz
* Single-phase input: R/L1 and S/L2/N terminals
Connect to a (three-phase induction) motor.
This is a negative potential terminal in the internal DC main circuit. DC common power
can be input across the PA terminals (positive potential).
DC common power can not connect to 1-phase 120V models.
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 shorting-
bar. 1-phase 120V models cannot be used with DC reactors.
