2.3.2. Torque Command Configuration (Current)
In this configuration, the output current to the motor is proportional to the current
command input. The current command configuration is shown in Figure 2-3. The
advantage to this configuration is the sine and cosine signals to the amplifier and a
tachometer are not required. This configuration will also drive both brush and brushless
DC motors.
