Abstract

Abstract: Based on the transformation of AC hoist TKD-A electric control system, the paper presents the control mechanism of realizing the power braking of wound type asynchronous motor by using the combination of all digital speed regulator and S7-300 PLC, and the setup of the key parameters of 6RA70 and PLC software process. This method has the advantages of stable and reliable operation and convenient parameter configuration, being of reference value to the transformation design of TKD-A system of mine hoister.

Key words: Mine hoist, Power braking, 6RA70, PLC
