2S86 ZLTECH 86 series DC 36V 48V AC 27V-75V closed loop stepping driver for CNC machine

Short Description:

ZLTECH closed-loop stepper driver 2S86 controls DSP chip and closed-loop control technology, so as to completely overcome the problem of step loss of open-loop stepper motor. Under light load, it can significantly improve the high-speed performance of the motor, reduce the heating degree of the motor and reduce the vibration of the motor, so as to improve the processing speed and accuracy of the machine and reduce the energy consumption of the machine. In addition, when the motor is continuously overloaded, the driver will output an alarm signal, which has the same reliability as the AC servo system.

Product Tags


1. Closed loop control technology, never lose step. The encoder is used as the position feedback, so that the stepper motor has the servo closed-loop characteristics, and the position deviation can be compensated in real time to fundamentally solve the problem of step loss of the stepper motor

2. Significantly improve the high-speed performance and acceleration and deceleration capability of the motor. The closed-loop control technology based on encoder feedback can improve the effective torque by more than 30% compared with the open-loop stepping driver.

3. Effectively reduce the heat generation of the motor. Based on the variable current control technology, the input current of the driver can be dynamically adjusted according to the load, effectively reducing the motor temperature by more than 15 ℃, and extending the service life of the motor.

4. The vibration noise of the motor is reduced, and the motor runs more stably. The variable current control technology is adopted to reduce the low-speed vibration noise and realize the smooth operation of the stepping motor.
