PURPOSE:To obtain the subject device capable of discriminating whether the rotation of the respective spindle driving systems of a spinning machine are deviated from the average of all the driving systems and readily sensing an abnormality in individual motors connected in parallel to one power source. CONSTITUTION:Power consumption or current of all the respective motors 1 is measured to calculate the average value for one unit of the motor 1. The power consumption or current for each motor 1 is measured and compared with the above-mentioned average value in a discriminating means. If a difference attains a prescribed value or more, a signal is outputted to an abnormality display device 9 to light an indicating lamp 13. |
