Page 7: Introduction
Introduction The Baldor “LD” Series Servo Control (see Figure 1-1) is a multi axis pulse width modulated (PWM), high performance servo control designed to be used with DC brush type permanent magnet servomotors. This transistorized servo control is a key component in motion control applications, providing not only converted DC power to the motor, but also precisely controlling current and velocity at the motor. -
