Application

Automatic acceleration and deceleration control. According to the mechanical inertia GD2, load characteristics automatically determine the acceleration/deceleration time, this function is usually used for large inertial loads.

The choice of acceleration and deceleration time. The speed of the speed control system can be determined by choosing the acceleration and deceleration time of the frequency control system.

If a shorter acceleration/deceleration time is selected, the production efficiency will be improved. However, if the acceleration time is chosen too short, it will Cause an overcurrent; If the deceleration time is selected too short, the frequency will drop too fast, and the motor is easy to enter the braking state (The motor speed is greater than the synchronous speed corresponding to the stator frequency, and the slip becomes negative), which may cause overvoltage.
