Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of this application.

[0032] The core of the present application is to provide a motor runaway protection system and method, which can effectively prevent the phenomenon of motor runaway caused by controller abnormality, and further protect the safety of controlled equipment and personnel.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction wit...

Abstract

The invention discloses a motor galloping protection system. The motor galloping protection system comprises a controller and a data processing circuit, wherein the data processing circuit controls the controller to be connected with a motor after receiving a starting signal for representing the normal work of the controller, so a motor is allowed to move according to the operation of the controller. By applying the above technical scheme, the controller can control the motor only when the starting signal is received, and the controller and the motor are in a disconnected state when the starting signal is not received, so the phenomenon of galloping of the motor under the conditions that the controller is abnormal and the like can be effectively prevented, and the safety of controlled equipment and personnel is further protected. In addition, the invention further discloses a motor galloping protection method which corresponds to the motor galloping protection system and has the same effect as the motor galloping protection system.

Description

technical field [0001] The present application relates to the technical field of servo control, in particular to a motor runaway protection system and method. Background technique [0002] Motor flying means that the speed is suddenly out of control, exceeding the maximum speed set by the motor and still not stopping. The reasons for the motor speeding can basically be divided into abnormal controller power-on, controller crash, abnormal feedback data reception and so on. Motor speeding will not only cause damage to the controlled equipment, but may even cause personal injury. In the prior art, after the phenomenon of motor speeding occurs, the specific details of the fault are generally searched, which has certain limitations and deficiencies. Especially the motor flying caused by the crash of the controller, there are many uncertainties and randomness in the occurrence of this situation, and it is difficult to find the cause of the crash of the controller. [0003] In v...
