Solution: most of hoist cranes use conical rotor motors. CHV190 frequency inverter provides an open-loop vector control way to ensure hoisting mechanism does not slip at low speed and full load, big and small cart mechanisms start and brake smoothly. For electric brake, it is recommended that commonly used resistor energy consumption braking way be used.
- It is simple and easy for use and can adapt to traditional operation mode of hoist crane.
- Improve performance, enable stepless speed change of the hoist crane that cannot change its speed, extend service life of the structure and the machine.
- It is highly integrated, and special-purpose function for crane can be realized without using PLC.
