This parameter defines four different modes to control inverter operation through external
terminals.0: Two-wire type 1
This mode is the most commonly used two-wire mode. The forward/reverse operation of
motor is determined by terminal DIx, DIy.
The terminal function is set as follows:
Terminals
Set value
Description
DIx
1
Forward run (FWD)
DIy
2
Reverse run (REV)
Of which, DIx and DIy are the multi-function input terminals of DI1 to DI10, the level is
active.

Terminal command mode: Two wire mode 1
1: Two-wire type 2
In the mode, DIx terminal is used as running enabled, while DIy terminal is used to determine
running direction.
The terminal function is set as follows:

2: Three-wire control mode 1
In the mode, DIn is used as enabled terminal, while DIx, DIy terminal are used to control
direction. The terminal function is set as follows:
Terminals
Set value
Description
DIx

Three-wire operation control
To run, firstly close DIn terminal, the forward or reverse of motor is controlled by the
ascendant edge of DIx or DIy pulse
