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:

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.

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:

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
To stop, you must disconnect DIn terminal signals Of which, DIx, DIy and DIn are the multi-
