Chapter 1 Introduction
1.1 Product Introduction
EL6/ELM Series AC servo products are cost-effective AC digital servo which is designed for
position/velocity/torque high accurate control, power range up to 1kw, which can provide a perfect solution for
different applications, performance with easy tuning process.
Based on CIA DS 301+DSP 402 sub-protocol, it can be seamlessly connected to the controller/drive that
supports this standard protocol.
Combined with abundant features like MFC, vibration suppression, Multi-mode filter function etc. It
provide machines a compact size, low tuning works, but high resolution encoder up to 23bit, an unique servo
system.
Talent features compared with pulse servo:
Reduce communication interference and extend communication distance
The reliability of pulse communication is reduced because the transmission cable of pulse signal is
vulnerable to electromagnetic interference. But CAN bus communication can significantly improve the
reliability of communication, reduce the influence of interference on instruction and extend the
communication distance due to the error detection, limitation and processing mechanism contained in the
protocol.
Improve motion performance
The trajectory planning of bus communication servo is realized in the drive. The controller only needs to
transfer the target position, speed, acceleration and other information to the drive. Therefore, the drive can
predict the motion parameters of the next moment in advance internally, and then take feedforward
measures to improve the motion performance.
Reduce system wiring complexity
Under the pulse communication mode, the controller needs to communicate with each drive through the
pulse cable connection, which often leads to the dense and complicated wiring of the machine equipment.
Under the CAN bus communication mode, the controller only needs to use the cable connection with one
of its drives, and the rest of the drives only need to use the chain mode to connect with the drive.
Reduce the number of required control unit ports, thereby reducing the cost
Multiple bus servo drive only need one port connect with movement control unit (motion controller or
movement control cards), without pulse module, also don’t need increases the number of drive control
card
because there are so many drives, and don’t need to consider computer slot number limitation. It can
save the cost of pulse module, control card and industrial control machine.
