Does a VFD replace a soft starter?
In addition to the functions of speed regulation control, energy saving and consumption reduction, the frequency converter can also realize the soft start function. Specifically, the soft start function of the inverter realizes the start control of the motor and reduces the start shock by controlling the frequency and voltage output by the inverter.
The soft start function of the frequency converter can replace the use of traditional soft starters. The frequency converter has the advantages of stable start, high efficiency and energy saving, small size and simple installation, but the price is higher than the traditional soft starter, and professional and technical personnel are required for installation and debugging. In practical applications, it is necessary to select an appropriate start-up control method according to the actual conditions of the equipment.
