Position out-of-tolerance alarm function ensures machining equipment safe operation. In contrast to the open-loop operation of stepper motor systems, servo motors are closed-loop systems, with built-in encoders that continuously communicate back to the controller, which makes any needed adjustments to ensure the target position is reached. By incorporating closed-loop servo control algorithms in these drives and pairing them with stepSERVO motors with high resolution encoders, we are able to create stepSERVO systems with performance that greatly exceeds conventional step motor performance. Any input mode may be used as position feedback, but the most common is a quadrature encoder either on the motor shaft or as a linear glass scale.
