The SPEC of each type of motor has some parameters such as maximum static torque and motor inertia. Each parameter has a certain relationship with load torque and load inertia. When selecting the motor, the moving condition requirements of the loading mechanism should be considered, such as the speed of the acceleration, the weight of the mechanism, and the movement mode of the mechanism (horizontal, vertical, rotation). When the inertia is large, the acceleration and deceleration torques need to be larger; when the acceleration and deceleration time is shorter, the motor output torque is also larger. Conventional open-loop stepper motors do not provide more torque for some complex applications, and step-servo motors are required.

But what are the advantages of step-servo motors instead of stepper motors?

A. Step-servo motor realizes position closed-loop control through the built-in high-resolution encoder. It has the characteristics of easy to use, no parameter setting, no chattering, anti-blocking and so on.

B. Step-servo motor can work 150% in short-term overload, which can adapt to high acceleration and deceleration applications.

C. The step-servo motor controller supports multiple control modes and implements multi-axis network communication through SCL commands, Modbus, CANopen, eSCL commands, EtherNet/IP or EtherCAT protocols.

What is a step-servo motor?

Step-servo motor is an innovative revolution for the world of a stepper motor, it enhances the stepper motors with servo technology to create a product with exceptional feature and broad capability.

Closed Loop

  • Very tight position and velocity control for the most demanding applications.
  • Robust servo loops that tolerate wide fluctuations in load inertia and frictional loading.

Easy Tuning

  • Pre-defined tuning parameters for maximum control performance and stability.
  • Easy selection list provides the level of control desired.
  • In most cases, NO extra manual tuning is required.

Fast Response

  • When performing fast point-to-point moves, the high torque output and advanced servo control provide a very responsive system far exceeding what can be done with a conventional stepper system.

High Torque

  • In full servo mode, all the available torque of the motor can be used.
  • The motor can provide as much as 50% more torque in many applications. High torque capability often eliminates the need for gear reduction.
  • Boost torque capability can provide as much as 50% more torque for short, quick moves.

Motion Monitoring

  • For difficult control situations were performing a precise move is necessary, the Quick Tuner provides an easy to use interface for performing and monitoring the motion profile.
  • Many common parameters such as Actual Speed or Position Error can be monitored to evaluate system performance.
  • The monitoring is interactive with the servo tuning capability so that optimum performance can be achieved.
