m_c I ment closed loop stepper sorry

- Closed-loop vector control technology ensures the high torque output, while ensuring that the motor does not lose step.
- With overvoltage, overcurrent, tracking error or over-error, and other protection features.
- Closed-loop driver can significantly improve the high-speed performance of the motor, increasing the effective torque of the motor by more than 30%; Effectively reduce the motor heating and motor vibration, the output current of the driver becomes larger or smaller as the load and speed increase or decrease; It can improve the processing speed and accuracy of the machine and reduce the energy consumption of the machine.
