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

Advantages of closed-loop stepper motors
- With the increase of the output torque, the speed of both decreases in a nonlinear manner, but the closed-loop control improves the torque frequency characteristics.
- Under closed-loop control, the output power/torque curve is improved because, in closed-loop, the motor excitation conversion is based on rotor position information, and the current value is determined by the motor load, so the current can be fully converted to torque even at low speed ranges.
- Under the closed-loop control, the efficiency-torque curve is improved.
- Using closed-loop control, we can get higher running speed, more stable and smoother speed than open-loop control.
- Using the closed-loop control, the stepping motor can be automatically and effectively accelerated and decelerated.
- The quantitative evaluation of the speed improvement of closed-loop control over open-loop control can be made by comparing the time to pass a certain path interval in step IV.
- With THE CLOSED-LOOP DRIVE, THE EFFICIENCY CAN be INCREASED TO 7.8 times, THE output POWER can be increased to 3.3 times, and the speed can be increased to 3.6 times. The performance of the closed-loop stepper motor is superior to that of the open-loop stepper motor in all aspects. Stepper motor closed-loop drive has the advantages of stepper motor open-loop drive and brushless DC servo motor. Therefore, the closed-loop stepper motor will be widely used in position control systems with high reliability requirements.
