Lifting Machinery：

 ◇ Fast response speed and large startup torque properlyalleviate vibrations at startup

◇ Zero-speed clasp brake and zero-speed open brake completely eliminate hook sliding and back flush

◇ Low torque pulse ensures more reliable operation of the device; especially in construction elevators, the device makes taking the elevators    

    more conformable

◇ All-round protection functions (frequency converter, motor, brake unit) and overload torque detection function prevent operations beyond the

     specification or on a mechanical failure

◇  Compact structure design is adopted and the built-in brake unit (for below 90KW) is optional.

◇ The Smartdrive function facilitates operations (easy for commissioning and maintenance), and helps save labor costs and time

◇ Intelligent LCD keyboard, real-time monitoring of key information, convenient man-machine interactions are provided.

◇ Thevoltage operation range is wide (-20% to +20%).

1）Compact volume；

2）Debugging is simple, optional LCD smart keyboard；

3）The built-in standard RS485/CANopen communication；

4）High performance PID functions ；

5）The built-in encoder interface, support the speed closed-loop control 。
