Terminal Function Description
Power Input
Terminal
R/L1, S/L2,
T/L3
Input terminals of three-phase 400V AC voltage (R/L1 and S/L2
terminals for single-phase)
Output Terminal
U, V, W
Inverter power output terminal, connected to motor.
Grounding
Terminal

without built-in braking unit).
P+
、
-(N)
DC bus-line output
P
、
-(N)
Externally connected to braking unit
P connected to input terminal “P” or “DC+” of braking unit, -(N)
connected to input terminal of braking unit “N” or “DC-”.
P, P+
Externally connected to DC reactor
Wiring for control loop as follows:
A+ B- TA TB TC DO1 DO2 24V CM OP1 OP2 OP3 OP4 OP5 OP6 OP7 OP8 10V AI1 AI2 GND AO1 AO2
Note: 15KW inverters and below 15KW have no A+
、
B- , DO2 and OP7, OP8 control terminal.

Functions of control terminals
The key to operate the inverter is to operate the control terminals correctly and flexibly. Certainly, the control
terminals are not operated separately, and they should match corresponding settings of parameters. This
chapter describes basic functions of the control terminals. The users may operate the control terminals by
combining relevant contents hereafter about “Defined Functions of the Terminals”.
