Abstract

The invention is suitable for the technical field of industrial equipment, and provides a power-off shutdown control method and device for industrial control equipment, and the method comprises the steps: obtaining a three-phase voltage value of the industrial control equipment; based on the obtained three-phase voltage value, detecting whether the industrial control equipment is in a power-off working condition or not; and when it is detected that the industrial control equipment is in a power-off working condition, controlling the industrial control equipment to operate in a decelerated mode to generate corresponding feedback energy until the industrial control equipment is shut down, wherein the feedback energy provides electric power for a bus of the industrial control equipment so as to increase the real-time bus voltage of the industrial control equipment. Therefore, when the industrial control equipment is in a power-off industrial control state, the deceleration feedback energy is used for supplying power, so that the industrial control equipment can decelerate according to process requirements in a power-on state until the industrial control equipment is shut down.

Description

technical field [0001] The application belongs to the technical field of industrial equipment, and in particular relates to a power-off shutdown control method and device for industrial control equipment. Background technique [0002] With the continuous promotion of industrial automation, industrial control equipment has been widely used. Industrial control equipment generally includes a variety of control equipment units such as frequency converters, PLCs, HMIs, and servos. When the input power is cut off, such as PLCs and servos lose power quickly due to lack of energy storage units, resulting in the The transmission equipment is out of control and cannot act according to the process requirements, resulting in waste of raw materials. For example, in the spinning frame, if the input power is cut off, the transmission module will be out of control and cannot act according to the process requirements, resulting in yarn breakage, which requires a lot of manpower and time for...
