Wiring Configurations

BL

3.2. Velocity Command Configuration

The speed of the motor is controlled by the amplifier in velocity command mode. In this mode, a velocity feed-

back signal is required. The feedback signal can be derived from an analog DC tachometer connected to the

+TACH pin, or from an incremental encoder that is connected to the sine and cosine pins (refer to Figure 3-

2). From this signal, the amplifier adjusts the velocity of the motor accordingly depending upon the velocity

command from the external controller. In this configuration, the amplifier closes and controls the velocity

loop.

This configuration can drive both brush and brushless DC motors.
