Drive Configuration
The SubDrive100 can also be set up to run a 1.1 kW or 1.5
kW pump if desired, but larger pumps will still produce to
the 1.5 kW curve and may only be operated with a 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 1.1 kW or 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.
Pump Sizing – SubDrive100
The SubDrive100 is configured at the factory for use with 0.75 kW pumps that are mounted to 1.5 kW
Franklin Electric three-phase motors.
In general, the SubDrive100 will enhance the performance of a
0.75 kW pump to a similar or better performance than a conventional 1.5 kW pump of the same flow
rating (pump series).
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.

DANGER
To select the proper 0.75 kW pump, first choose a
1.5 kW curve that meets the application’s head and
flow requirements. Use the 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 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.
