DSA-MTR12A2  DDS-TLII AC SERVO DRIVE

which receives instructions from the controller and drives the servo motor to make precise movements according to the required Angle, speed and position.

“dds” usually refers to the abbreviation of “Digital Drive System”, which refers to the use of digital technology to

achieve the control and drive of servo drives. Digital technology makes control more precise, fast and flexible.

“tli” may be an identifier or abbreviation unique to the drive manufacturer, and the specific meaning may require

consulting the drive’s official documentation or contacting the manufacturer for more detailed information.

Overall, the DSA-MTR12A2 is an AC servo drive with digital technology (dds) for precise control of the motion of AC servo motors.

The principle of AC servo driver mainly involves signal processing, feedback system, control algorithm and power amplifier.

Signal processing: The servo driver receives the command signal from the controller. These signals can be analog

(such as voltage or current) or digital (such as pulse signals or communication protocols).
Feedback system: Servo drives usually contain a feedback system to detect the actual motion state of the motor. This is

usually achieved through an encoder or sensor mounted on the motor shaft. The feedback system compares the actual

motion state with the control signal in order to adjust the motion of the motor.
Control algorithm: The servo drive uses an internal control algorithm to calculate the control signal to drive the motor.

These algorithms usually adopt closed-loop control technique, that is, the control signal is adjusted according to the signal

and target state of the feedback system.
