SubDrive1500
The SubDrive1500 is capable of use with 0.75 kW (1.0 hp) pumps that are mounted to
1.5 kW (2.0 hp) Franklin Electric three-phase motors. In general, the SubDrive1500 will
enhance the performance of a 0.75 kW (1.0 hp) pump to a similar or better performance
than a conventional 1.5 kW (2.0 hp) pump of the same ow rating (pump series).
To select the proper 0.75 kW
(1.0 hp) pump, rst choose
a 1.5 kW (2.0 hp) curve that
meets the application’s head
and ow requirements. Use
the 0.75 kW (1.0 hp) pump in
the same pump series ( ow
rating). The SubDrive1500 will
adjust the speed of this pump
to produce the performance of
the 1.5 kW (2.0 hp) curve.
An EXAMPLE of this is
illustrated in the graph at right.
Please consult the pump
manufacturer’s pump curve for
your speci c application.
The SubDrive1500 can also be set up to run a 1.1 kW (1.5 hp) or 1.5 kW (2.0 hp) pump if
desired, but larger pumps will still produce to the 1.5 kW (2.0 hp) curve and may only be
operated with a 1.5 kW (2.0 hp) motor. To operate a di erent pump size, a DIP switch must
be positioned to select the correct pump rating. Otherwise, the SubDrive1500 may trigger
erroneous faults.
See the Basic Set-up section of this manual for DIP switch information and settings.
Serious or fatal electrical shock may result from contact with internal electrical components.
DO NOT, under any circumstances, attempt to modify DIP switch settings until power has been
removed and 5 minutes have passed for internal voltages to discharge! Power must be removed for
DIP switch setting to take e ect.
