Control Techniques EN-204-00-000 EN Servo Drive Unit

Module Feature

EN-204-00-000 belongs to EN series fully digital AC servo drive manufactured by Control Techniques. It supports seven selectable operation modes including speed, torque and closed-loop position control. Accept snap-on FM function modules for indexing, motion programming and fieldbus communication such as Profibus, DeviceNet and Ethernet. Built-in diagnostic display with time-stamped fault log, integrated dynamic braking transistor. Widely applied in packaging machinery, material handling, cutting equipment and precision multi-axis automation systems.

Working principle

AC input power is rectified to DC bus. IGBT power stage outputs three-phase variable voltage and frequency AC to drive permanent magnet servo motor. Encoder feedback signal is received by drive to realize closed-loop torque, speed and position regulation. Dynamic braking circuit consumes regenerative energy during motor deceleration. Optional FM expansion module adds advanced motion sequence and bus communication functions.
