Abb Cma 131 Servo-motor Drive Encoder Module

What is the ABB CMA 131 Servo-Motor Drive Encoder Module?

The ABB CMA 131 is a feedback module within the ABB servo systems that interprets the servo motor encoder signals. The encoders work as the “eyes” of a servo motor, allowing the controller to understand the exact position, rotation direction, and speed of the motor shaft.

These encoder signals are received by the CMA 131 module, processed, and sent as accurate feedback to the servo drive for fast real-time adjustments, thus guaranteeing stability, precision, and smooth control of motor motion in industrial operations.
