PURPOSE:To discriminate normalcy or abnormality accurately in its early stages by memorizing initial value in case of starting of outputs from a summing amplifier regarding each motor and adopting value obtained by adding fixed voltage to the value memorized as abnormality discriminating voltage value. CONSTITUTION:A memory storage 7-1 memorizes outputs from the summing amplifier when each motor is started while value memorized is transmitted over an adder 7-3 by the command of a scanning circuit 7-2. Predetermined value is added to data transmitted from the memory storage 7-1 in the adder 7-3, data added is transmitted over a comparison circuit 7-4, and compared with data from the scanning circuit 7-2, and the normalcy or abnormality of the motor is decided. |
