Shandong Sokon Electric Co., Ltd. is a comprehensive enterprise engaged in the research, development, sales, service, installation, debugging, maintenance, and integration of variable-frequency drives and high and low voltage electrical equipment. Our mission is to provide high-quality products, reduce production costs, and maximize customer value. The company is equipped with a marketing department, a research and development department, a system engineering department, and a maintenance department.

Due to the motor being in a blocked-rotor state, the back electromotive force E is 0. As a manufacturer of variable-frequency drives for rotary cutting machines, at this point, the AC impedance value Z is 0, and there is only a small DC resistance. Therefore, a large current is extremely dangerous and could trigger an overcurrent trip (OC). The principle for setting the braking time is to prefer a longer duration rather than a shorter one to avoid overvoltage trips (OE). Specific values for deceleration time can be found in Table 1. For water pumps and fans, free braking is recommended; implementing rapid and strong braking is prone to severe "water hammer" effects.

Surges from lightning or induced lightning can also damage variable frequency drives, such as those in Binzhou. Additionally, when the primary side of the power system features a vacuum circuit breaker, the variable frequency drive used in cutting machines can generate high surge voltages during short-circuit switching. To prevent overvoltage damage caused by surge voltages, it is usually necessary to add surge-absorbing devices like voltage-sensitive resistors at the input of the variable frequency drive. An RC surge absorber should be added to the vacuum circuit breaker. If there is a vacuum circuit breaker on the primary side of the transformer, it should be ensured that the variable frequency drive is disconnected before the vacuum circuit breaker operates in the control sequence.

Controllable acceleration feature

Variable frequency speed control can start at zero speed and accelerate uniformly according to user requirements, and the acceleration curve can also be selected (linear acceleration, S-shaped acceleration, or automatic acceleration). However, when starting at industrial frequency, it will cause severe vibration in the motor or the shaft or gear of the connected mechanical parts. This vibration will further exacerbate mechanical wear and tear, reducing the lifespan of mechanical components and the motor. Additionally, variable frequency start can also be applied to similar filling lines to prevent bottles from being overturned or damaged.
