Motor abnormality detecting device, control method of motor abnormality detecting device, and image forming apparatus

摘要

In the conventional motor malfunction detecting apparatus, a comparator is provided for each motor driver, and the output of a plurality of comparators is wired or connected to suppress the increase in the scale and cost of the system. However, in such a configuration, when an overcurrent occurs, it is impossible to specify which motor related overcurrent occurs.In the present invention, an analog switch is provided on the input side and the output side of the comparator connected to the current detecting resistor using the resources prepared in the analog FPGA to control the on / off state of the analog switch.As a result, it is possible to provide a motor malfunction detecting device capable of specifying a portion where the overcurrent occurs.Selection diagram
