Motor Current/Resistor Settings for Compumotor Motors
The next table shows motor current settings for Compumotor OS and RS motors.
Choose a resistor from the table that matches drive current to the motor your are
using. DIP switches that set the current range—SW3-#7 and SW3-#8—should be
in the
off position for these resistor values (off is the factory default position).

Motor Current/Resistor Settings for Other Motors
If you use a non-OS or non-RS motor, carefully follow the motor manufacturer's
instructions regarding motor wiring and the proper operating current. Compumotor
recommends a motor inductance of between 1 mH and 10 mH, measured in
series or parallel (0.2 mH – 80 mH is acceptable). The next table shows resistor
values that you must use to properly set motor current when using the OEM750/
OEM750X with a non-OS or non-RS Series motor. The drive can generate from
0.2 to 7.5 amps, determined by the
motor current range DIP switches (SW3-#7
and SW3-#8).
