OEM650/OEM650X • INSTALLATION
OEM size 34 motors are internally wired in parallel. A 75VDC
power supply (OEM300) must be used to achieve maximum perfor-
mance; however, lower voltage power supplies may be used (less
than 75VDC but must be greater than 24VDC). The lower voltage
power supply will not adversely affect the system's low-speed
performance, but it will not yield the optimum high-speed perfor-
mance achieved by using the 75VDC power supply.
❐ Size 34 motors are internally wired in a parallel configuration
(OEM83-62-MO, OEM83-93-MO, OEM83-135-MO)

5. Set motor current. Table 2-7 contains the proper motor current
settings for Compumotor OEM motors. A 1/4 watt resistor
connected between REF and CURRENT sets motor current.
Adjust the drive current to match the motor that you are using.

For best installation
results, be sure that the
resistor lead wire is long
enough for easy insertion
into the REF and
CURRENT terminals.
