ELECTROMOTIVE DRIVE CONTROL SYSTEM, AND ELECTROMOTIVE DRIVE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To prevent malfunction of an electric machine controller when an abnormal signal is delivered from an upper controller to the electric machine controller.

SOLUTION: The electromotive drive control system comprises an information receiving means for receiving a digital signal transmitted from an upper controller as an input signal, a means for limiting the received input signal by a preset digital limit value, and a means performing predetermined control processing by receiving a processed signal subjected to limitation. The received input signal is limited by a preset digital limit value and predetermined control processing is performed based on the processed signal subjected to limitation. Since a processed signal exceeding a limit value is not delivered to the control means, malfunction of an electric machine controller can be prevented.
