RS485 Communication Controlling Type Stepper Drive
Strong compatibility and scalability
It is compatible with pulse signal input and I/O internal control mode. One drive is with multiple functions bringing more expansion possibilities, greatly reducing system costs.
RS485 Communication
With RS485 communication connection, based on standard ModbusRTU protocol, it can support multi-axis RS485 motion control network.
DE series pulse type closed-loop driver
"Closed-loop stepper" drive system is the innovative integration of closed-loop control technology into the stepper motor by Division according to market demand and prospects, creating a new A drive for performance. Successfu-lly solved the problems of dislocation and lost steps of the traditional stepping system, and further improved the sp-eed and acceleration of the stepping motor can effectively reduce the cost of equipment use. Closed-loop stepping not only has the same motor installation size as traditional stepping 28/36/42/57/60/86/110/130mm, etc., but also Simple and easy to set up, the performance is improved by more than 50% compared with the traditional stepping, and the price is less than half of the AC servo. It is the first choice for medium and low speed servo applications!
EtherCAT FieId Bus CIosed Loop Step Drive
Product Overview
EtherCAT series bus-type stepper products are bus-type stepper drivers that add bus communication function on the basis of the original high-voltage pulse-type stepper drivers. Pick Using the EtherCAT bus communication inte-rface, based on the EtherCAT slave technology, the transmission rate of 100Mb/s realizes the real-time control and real-time data transmission of the servo system. only Support CSP, HM operation mode. The driving voltage is AC200V~240V, and it is suitable for various types of three-phase hybrid stepper with current below 7.0A and outer diameter of 86~130mm.into the motor. Compared with the traditional pulse servo driver, the driver is especially suitable for applications in long-distance, multi-axis linkage applications, such as manipulators, packaging machi-nery, etc.The wiring can be greatly reduced and the reliability of the drive operation can be enhanced.

The major components of a stepper driver are:
Power input: This is the connection point for the power supply that provides the voltage and current required to drive the stepper motor.
Microcontroller or Processor: This component controls the operation of the stepper motor by sending signals to the driver circuits.
Driver circuits: These circuits control the current flowing through the motor windings by switching the power MOSFETs or transistors.
Current sense circuit: This circuit senses the current flowing through the motor windings and provides feedback to the driver circuits to regulate the current.
Step and direction input: This is the input signal that determines the direction and step size of the motor.
Heat sink: This is a passive cooling device that helps dissipate the heat generated by the power MOSFETs or transistors.
Overall, the stepper driver is responsible for accurately controlling the movement of a stepper motor by providing the appropriate voltage and current to the motor windings, based on the signals it receives from the microcontroller or processor.
