12. How to connect and configure a Run/Stop switch
with Forward/Reverse selection
The parameters described in Section 5 enable
Run/Stop operation via the red and green
buttons on the Inverter.
If this is unsuitable for the application, remote
switches can be used instead.
This section explains how to enable 2-wire
control with Run/Stop and Forward/Reverse
commands via separate selector switches.
Ensure the Inverter is in “Remote” mode
before continuing.
12.1 Parameters to change for remote Run/Stop
12.2 Connecting the Switch
A wiring diagram is shown in the illustration
opposite.
Two suitable 2 position NO (
)
switches should be installed: One between
terminals 4 and 5 (Run/Stop) and the other
between terminals 2 and 5 (Forward/Reverse).
A “General Enable” link is required between
terminals 1 and 5.
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.
Terminal 5 (COM) is a common connection for
terminals 1-4, 6 and 8 and has no other
function.
Normally Open
If this link is removed whilst
the motor is running, the motor will coast to a
stop (rather than controlled deceleration).
