2.4. Integrated Configurations
The BA amplifiers can be integrated into a system using 3 basic configurations; velocity
command, current command, and dual phase command. Each of these has their
advantages and disadvantages depending upon the user’s specific needs.
2.4.1. Velocity Command Configuration
In the velocity command configuration the speed of the motor is controlled by the
amplifier. A feedback signal from either a DC tachometer or an incremental encoder is
monitored by the amplifier. 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. The velocity
command configuration is shown in Figure 2-7. This configuration can drive both brush
and brushless DC motors.
