Title:
METHOD FOR DETECTING TEMPERATURE OF BRAKING RESISTOR IN DRIVER
Document Type and Number:
WIPO Patent Application WO/2021/253634
Kind Code:
A1
Abstract:
The present invention relates to the technical field of servo motor drivers, and specifically relates to a method for detecting the temperature of a braking resistor in a driver. Real-time power parameters of a braking resistor are obtained by means of calculations after a driver powers on, and normalization processing is performed to form a corresponding temperature rise curve function; corresponding power parameters can be obtained at any subsequent moment by means of the temperature rise curve function, and temperature parameters corresponding to said moment are calculated to implement the detection of the temperature of the braking resistor. The entire detection method does not require the addition of hardware equipment, i.e., devices are conserved, while the method also has the advantages of being highly reliable, being simple and convenient to use, etc.
