2.2.2. DC Brush Motor Connections
The configuration shown in
is an example of a typical DC brush motor connection. Refer to
for information on motor phasing.
When you connect the motor between amplifier phases A and C, it will produce twice the nominal bus
voltage across the motor. This is because phase C will generate the same voltage as phase A but with
opposite polarity. To generate the nominal bus voltage, connect the motor between Phase A and RT. RT
is the 0 V return path for the motor power supply.
Use the lowest voltage configuration possible to minimize heat generation in the amplifier.
