12. How to configure “3-Wire” control with Run/Stop
pushbuttons and Forward/Reverse selection
If this is unsuitable for the application, remote
switches can be used instead.
The parameters described in Section 5 enable
Run/Stop operation via the red and green
buttons on the Inverter.
This section explains how to enable 3-wire
control with Run and Stop commands via
separate pushbuttons and Forward/Reverse
selection via a selector switch. Note that once
this procedure is complete, the Run/Stop
buttons on the Inverter can no longer be used.

pushbuttons should be installed. The “Run”
pushbutton should include a Normally Open
contact between terminals X1 and X3 and the
“Stop” a Normally Closed contact between
terminals 24V and X3.
A momentary connection between X1 and X3
will start the motor. It will continue to run until
the connection between 24V and X3 is broken.
12.2 Connecting the Switches
Note that the Forward/Reverse switch only
selects the direction of rotation - it will not start
or stop the motor. If the application only
requires the motor to turn in one direction, the
Forward/Reverse switch can be omitted.
For “Forward/Reverse” a suitable 2 position
NO (Normally Open) switch should be installed
between terminals 24V and X2.
