Configuring OEM Servo Drives for BE Motors

OEM770 or OEM670 servo drives may be configured to run BE series servo motors.  BE series motors are not recommended for use with OEM675 servo drives, which are current loop optimized for motors with a low electrical time constant, such as the SM series.
The resistor values necessary to run BE series servo motors with an OEM770 or OEM670 servo drive at 75 VDC input are as follows.  For supply voltages less then 75 VDC, calculate R22 with the following equation:
R22 = (R22old) * Vsupply / 75.
Where R22old is from the table below (at 75 VDC). R23, R24 and R25 do not change with voltage.
Please note that Jumper JU1 should be in for all of the following configurations.
