10. How to connect and configure a Run Forward or
Run Reverse switch
10.1 Parameters to change for remote Run/Stop
If this is unsuitable for the application, a remote
switch can be used instead.
The procedure described in section 7 enables
Run/Stop operation via the red and green
buttons on the Inverter keypad.
This section explains how to enable 2-wire
control with Run Forward / Stop / Run Reverse
commands via a single selector switch.
When set to operate in this way, the Inverter
can no longer be operated via the integrated
keypad.
If terminals DI3 and DI4 are connected to 24V
at the same time the motor will stop.
A wiring diagram is shown in the illustration
opposite.
When a connection is made between terminals
24V and DI3, the motor will run forward. When
terminals 24V and DI4 are connected, the
motor will run in reverse.
The selected direction
of rotation is indicated by the “FWD” lamp on the
Inverter.
Note: the “FWD” lamp will flash to indicate
that the Inverter is waiting for a direction
command. This is normal.
A suitable 3 position NO (Normally Open)
switch should be installed between terminals
24V, DI3 and DI4. The centre position should
remain open circuit.
10.2 Connecting the Switch
When the NPN/PNP jumper is set to PNP (the
default), the 24V terminal is a common connection
for the digital terminals (terminals prefixed with
“D”). If you prefer to set the jumper to NPN, use CM
as the common instead.
