11. How to connect and configure a Run/Stop switch
with Forward/Reverse selection
If this is unsuitable for the application, remote
switches can be used instead.
The procedure described in section 7 enables
Run/Stop operation via the start and stop
buttons on the Inverter keypad.
This section explains how to enable 2-wire
control with Run/Stop and Forward/Reverse
commands via separate selector switches.
When set to operate in this way, the Inverter
can no longer be operated via the integrated
keypad.
11.1 Parameters to check for remote Run/Stop
If the application only requires the motor to turn
in one direction, the Forward/Reverse switch
can be omitted.
11.2 Connecting the Switches
Note that the Forward/Reverse switch only
selects the direction of rotation - it will not start
or stop the motor. The direction can be set
either before the motor is started or whilst it is
running.
Two suitable 2 position NO (Normally Open)
switches should be installed: One between
terminals 24V and DI1 (Run / Stop) and the
other between terminals 24V and DI2
(Forward / Reverse).
A wiring diagram is shown in the illustration
opposite.
