3.4 VFD Run/Stop Control
To give a Phase Technologies VFD a
RUN/STOP
command remotely, connect wires as
shown and make sure the VFD settings match those shown in
. These are default
settings, so no changes should need to be made. On the portal dashboard, toggle
Relay 1
and hit
Send Commands
button. The relay icon next to
Relay 1
will now show that the NO
terminal is connected to C. The label of
Relay 1

3.5 Reset VFD Fault
Install Tip
Not all Phase Technologies drives have this feature. Navigate to the
AUX SELECT
parameters in your drive to ensure it has this ability.
Some faults on Phase Technologies VFDs require manually cycling incoming power to
reset. To do this remotely, connect wires as shown in
AUX 2 SELECT
on the VFD to
5 (Reset Drive Fault)
. If a Phase Technologies VFD encounters a non-
resettable fault, use the portal to turn Relay 2
ON
, which will cycle power to the VFD and
reset the fault. If the drive encounters another fault, Relay 2 will need to be cycled
OFF
then back
ON
to reset the fault.
