Technical details and manufacturing context for Servo Motors & Drives

Definition
In an XY Gantry System, servo motors and drives work together to provide accurate positioning and velocity control for the moving axes. The drive receives command signals from the system controller and supplies the appropriate power to the servo motor, which then moves the gantry or tool head to the exact programmed coordinates with high repeatability.
Working Principle
The system controller sends position/velocity commands to the servo drive. The drive compares these commands with feedback from encoders on the motor shaft. Based on the error signal, the drive adjusts the current and voltage supplied to the motor windings, creating precise electromagnetic forces that rotate the motor shaft to the desired position.
