The DL-1200RTU servo motor module is part of the servo system, which receives the control signal from the servo amplifier and controls the rotation of the motor. The servo motor module consists of a servo motor and a servo driver, which are usually used in combination.

Servo motor module features:

High precision.

Wide speed range.

Good dynamic performance.

Small size, large power.

The working principle of the DL-1200RTU servo driver is to drive the executive motor under the action of the control signal, and its internal structure is composed of the power supply circuit, the relay board circuit, the main control board circuit, the driver board circuit and the power conversion circuit.

The servo drive is equivalent to the brain in the servo control system, and the execution motor is equivalent to the hands and feet, which is mainly to adjust the speed of the motor and is an automatic speed regulation system.

The specific working principle of the servo driver is that under the action of the relay board, the control signal and the detection signal are sent to complete the double closed-loop control, including speed adjustment and current adjustment, to realize the speed control and commutation control of the motor. The drive board of the DL-1200RTU driver receives the signal from the main control board to drive the power conversion circuit and implement the normal operation of the motor.

The components of servo and drive unit mainly include servo control unit, power drive unit, communication interface unit, servo motor and the corresponding feedback detection device.

The DL-1200RTU servo control unit includes position controller, speed controller, torque controller and current controller. The power drive unit rectified the input three-phase or mains through the three-phase full bridge rectifier circuit to obtain the corresponding direct current, and then output alternating current through the inverter frequency conversion to drive the servo motor. The communication interface unit is responsible for transmitting instructions and feedback signals.
