SubDrive/MonoDrive
Pump Sizing – SubDrive100
The SubDrive100 is configured at the factory for use with 1.0 hp (0.75 kW) pumps that are
mounted to 2.0 hp (1.5 kW) Franklin Electric three-phase motors. In general, the SubDrive100
will enhance the performance of a 1.0 hp (0.75 kW) pump to a similar or better performance than
a conventional 2.0 hp (1.5 kW) pump of the same flow rating (pump series).
To select the proper 1.0 hp (0.75 kW)
pump, first choose a 2.0 hp (1.5 kW)
curve that meets the application’s
head and flow requirements. Use the
1.0 hp (0.75 kW) pump in the same
pump series (flow rating). The
SubDrive100 will adjust the speed of
this pump to produce the performance
of the 2.0 hp (1.5 kW) curve. An
EXAMPLE of this is illustrated in the
graph at right. Please consult the pump
manufacturer’s pump curve for your
specific application.
Drive Configuration
The SubDrive100 can also be set up to run a 1.5 hp (1.1 kW) or 2.0 hp (1.5 kW) pump if desired,
but larger pumps will still produce to the 2.0 hp (1.5 kW) curve and may only be operated with
a 2.0 hp (1.5 kW) motor. To operate a different pump size, a DIP switch must be positioned to
select the correct pump rating. Otherwise, the SubDrive100 may trigger erroneous faults.
To configure the SubDrive100 for a 1.5 hp (1.1 kW) or 2.0 hp (1.5 kW) pump, locate the DIP
switch marked “SW1”. Use a small screwdriver (provided) to change the DIP switch setting
according to the chart as shown.

WARNING !
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 effect.
