Requirements of diesel winch for frequency conversion control system

Similar to elevators, diesel winch is special equipment, so they have strict requirements for reliability and safety. They also put forward corresponding requirements for frequency conversion control system

1. It has good constant torque performance in the full speed range.

2. Good starting and braking performance - fast, stable and accurate starting and braking.

3. When heavy objects fall (except for no-load or light load), they all fall by self weight. In order to overcome the constant acceleration of gravity acceleration, the motor must produce enough braking torque to make the weight drop steadily at the required speed.

4. The stopping distance shall not exceed 5% of the lifting or descending distance of the hook in one minute, and there shall be no "sliding hook" before and after the heavy object stops in the air.
