Fault diagnosis method for roller conveyors, roller conveyors and control for conveyor

摘要

Disclosed is a fault diagnosis method for a roller conveyor (20), of the rollers (23), brushless motors (43) and zones of controllers (1a, 1b) for controlling the brushless motors (43), wherein the brushless motors (43) and / or the rollers (23) in each case a rotation detector (31) and the zones of controllers (1a, 1b) in each case a driver which contains a logic circuit, a memory (16), which contains a program, as well as a microcomputer (15) have. The program includes a fault diagnosis program and a criteria parameters. The zones of controllers (1a, 1b) determining a respective operating parameters of the brushless motors (43) and / or the relief (23), in order to thereby obtain a comparison of the operating parameter with the criteria parameters and to perform a fault in the roller conveyor in a case to determine in which a result of the comparison is beyond a predetermined level is.
