Problems solved by technology

In the normal operation of the motor, if the power transmission signal of the motor control cabinet or the motor running signal is lost instantaneously, the motor will immediately trip and stop, even if the signal is lost for a short time and then returns to normal, the motor will immediately trip and stop, which will Lead to unsustainable production, reduce production efficiency, and affect production progress
[0004] The existing technology has at least the following technical problems: Even if the signal is lost for a short time and then returns to normal, the motor will immediately stop, which will cause the production to not continue, reduce production efficiency, and affect production progress

Abstract

The application provides an IO fault delay processing device for a motor control system. The device includes: a control cabinet power transmission signal interface for obtaining a motor control cabinet power transmission signal; a motor operation signal interface for obtaining a motor operation signal; The current signal interface is used to obtain the current value of the motor current; the processor is used to process the power transmission signal of the motor control cabinet according to the power transmission signal, the motor operation signal and the current value to obtain a new motor control cabinet Power transmission signal: the control cabinet power transmission signal output interface is used to output the new motor control cabinet power transmission signal. By using various embodiments of the present application, unnecessary tripping of the motor can be avoided, thereby increasing the continuous running time of the motor.

Description

technical field [0001] The present application relates to the technical field of automation control, in particular to an IO fault delay processing device of a motor control system. Background technique [0002] In the field of industrial automation control, the DCS system is a commonly used automation control system, and the motor is a common controlled device. [0003] In the prior art, the normal operation of the motor adopting the DCS system needs to meet the following two conditions: the preparation signal for power transmission of the motor control cabinet continues to be normal, and the operation signal of the main circuit contactor of the motor continues to be normal. In the normal operation of the motor, if the power transmission signal of the motor control cabinet or the motor running signal is lost instantaneously, the motor will immediately stop, even if the signal is lost for a short time and then returns to normal, the motor will immediately stop, thus As a res...
