Problems solved by technology

Therefore, independent control is required, and the existing wiring will cause complicated wiring due to the large number of driving devices, which will cause a burden to the wiring installers
[0003] The external three-phase power supplies power to the PLC or equipment, and the PLC also controls the connected equipment to regulate the work of the equipment. On the basis of the above structure, if there are many equipment, one PLC will cooperate with one equipment. It can be seen that when multiple equipment and multiple In the case of PLC, the connection control between devices becomes complicated

Description

technical field [0001] The invention relates to the field of hardware circuits, in particular to a switching module integrating hard start, soft start and variable frequency start. Background technique [0002] Generally speaking, for the drive control of the motor and the connection of the power grid to the equipment, it is necessary to consider the working environment to determine the startup mode of the equipment. Some equipment motor drives require hard startup, some require soft startup, and some require variable frequency startup. Therefore, independent control is required, and the existing wiring will cause complicated wiring due to the large number of driving devices, which will cause a burden to the wiring installers. [0003] The external three-phase power supplies power to the PLC or equipment, and the PLC also controls the connected equipment to regulate the work of the equipment. On the basis of the above structure, if there are many equipment, one PLC will coop...
