Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0023] see figure 1 , the specific implementation process of the technical solution is:

[0024] (1) When the motor is running normally, it is judged whether the control bit turns on the function of the belt brake detection function, if yes, go to step (2), if not, go to step (7);

[0025] (2) judge whether the sample parameter of setting is non-zero, if yes, execute step (3), if not, generate prompt fault information display parameter error, and execute step (7);

[0026] (3) Judging whether the motor has detected a slight belt brake during this operation, if yes, perform step (5), if not, perform step (4);

[0027] (4) Through the continuous detection of the motor, it is judged whether the feedback torque is greater than the torque of the sl...

Abstract

The invention discloses a detecting method for realizing band brake running of a motor. The method can compare the torquemoment checked in the process of checking motor running with the torquemoment in the process of system normal running, and generates fault codes when the torquemoment in the process of system is bigger than the normal value in a certain range. Two grade fault codes are set according to the seriousness of band brake running: indicative fault codes generated by slight contracting brake and system stop fault codes generated by serious contracting brake. The technical proposal can be used for preventing motor current from losing control caused by contracting brake, friction, etc., which can cause the occurrence of the situations such as safety accidents, component damage, etc. At the same time, the detecting method is convenient for site workers to diagnose the faults such as contracting brake, etc.

Description

Technical field: [0001] The invention relates to the technical field of motor control of a brake device in an elevator, in particular to a method for detecting the operation of a motor with a brake to prevent friction of the brake when the elevator motor is running. Background technique: [0002] At present, the monitoring of the brake when the motor is running in the current market products is generally judged by the brake detection switch, but because the brake travel is too small, the switch often malfunctions, which brings certain troubles to the control; for this, it is necessary to use a A more effective technical solution to monitor the status of the brake during operation in real time. [0003] The scheme description of the brake detection switch: the working principle of the brake is to stop the motor through the friction between the brake pad and the hub. During the closing and opening process of the brake, the gap between the brake pad and the hub reflects the st...
