1,Zero-speed clasp brake and zero-speed open brake completely eliminate hook sliding and back flush.
2,Low torque pulse ensures more reliable operation of the device; especially inconstruction elevators, the device makes taking the elevators more conformable.
3,All-round protection functions (frequency converter, motor, brake unit) and overload torque detection function prevent operations beyond the specification or on a mechanical failure.
4,Compact structure design is adopted and the built-in brake unit (for below 90KW) is optional.
5,The Smart drive function facilitates operations (easyfor commissioning and maintenance), and helps save labor costs and time.
6,Intelligent LCD keyboard, real-time monitoring of key information, convenient man-machine interactions are provided.
7,Thevoltage operation range is wide (-20% to +20%).












1, Excellent open-loop vector control performance, open-loop realize zero-speed opening brake, eradicate slipper, 150% load smoothly up and down;
2.,The control speed is high precision, fast response, and the process requirements such as lifting, turning and translation are well realized;
3, high reliability, better adapt to the open air environment;





1. Fast response speed, low frequency and large torque output, better suppression of vibration phenomenon at startup; zero speed brake and opening brake, completely eliminate slippery and backflushing.
2. Accurate current output makes the matching between load, output power and running speed reach a ideal state. Even under the condition of mechanical tolerance, it can run at high speed and improve the efficiency of material feeding.
3, frequency control can achieve stable start and stop braking, mechanical impact is small, can extend the life of the crane machine.
4, high reliability, closed circuit structure and multi-layer three anti-paint thickening process, the protection level reaches IP40, more suitable for the harsh environment in the field.
5, motor output power optimization, while improving work efficiency, can reduce energy consumption, resulting in good economic benefits.
6. The industrial-grade large-size intelligent LCD keyboard displays various operating parameters, which is convenient for the operator to grasp the running status information from time to time, and can realize remote control, fault diagnosis and parameter correction.
7. Wide voltage range (±20%), which satisfies the normal operation of large fluctuations in the field voltage.
