11. How to connect and configure a Run/Stop switch
with Forward/Reverse selection
The procedure described in section 7 enables
Run/Stop operation via the red and green
buttons on the Inverter keypad.
If this is unsuitable for the application, remote
switches can be used instead.

"Forward / Reverse"

for Run with Forward/Reverse selection.
11.2 Connecting the Switch
A wiring diagram is shown in the illustration
opposite.
The PC terminal is a common connection for
terminals RL, RM, RH, STF and STR when the
jumpers are set in "Source" (the default). If the
jumpers have been changed to "Sink", use SD as
the common instead.
Two suitable 2 position NO (Normally Open)
switches should be installed: One between
terminals PC and STF (Run/Stop) and the other
b e t w e e n t e r m i n a l s P C a n d S T R
(Forward/Reverse).
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.
If the application only requires the motor to turn in
one direction, the Forward/Reverse switch can be
omitted.
The Inverter must be in external control mode to
operate in 3-wire control. Check that the "EXT"
indicator is illuminated to confirm. The PU/EXT key
can be used to change the mode if required.
