Kollmorgen / Seidel 60WKS-CE240/6PB Analog Servo Drive Amplifier

The Kollmorgen / Seidel 60WKS-CE240/6PB is an analog servo drive amplifier engineered to command brushless synchronous servo motors in precision motion control applications. It delivers 240W rated power with 6A continuous output current (4-quadrant operation) and 15A peak current capability over 5 seconds. The drive employs a 3-phase PWM transistor power stage with integrated PI-controllers for speed and current regulation, accepting RLG rotor-position and tacho feedback signals for trapezoidal commutation.
