NO.6 Detailed Function Description
37
◆ Three-wire connection
Three multi-functional terminals shall be used for three-wire connection to enable switching
between forward and reverse rotating, which is widely used for optoelectronic switch and
other cases, as shown in Figure 6-7.
B1: Forward Button (normally open), with effective edge
B2: Reverse Button (normally open), with effective edge
B3: Stop Button (normally closed), with effective edge
P001=1 under external terminal control
P044=02 X1 is set as forward function
P045=03 X2 is set as reverse function
P046=04 X3 is set as stop function
(3) Actuation description
Triggering of X1 enables inverter forward (start);
Triggering of X2 enables inverter reverse;
Disconnection of normally closed button B3 enables inverter
stop.

◆Two-wire connection
Enable start, stop, forward/reverse switching, as shown in Figure 6-8.
(1) K1 and K2 refer to effective level.
P001=1 under external terminal control
P044=01 X1 is set as RUN function
P045=05 X2 is set as FOR/REV switching function
(3) Actuation description
Upon closing of K1, inverter runs in a forward way when K2
is disconnected and in a reversed way when K2 is closed.
