ータ誤動作検出回路。 origin signal output means for outputting an origin signal when a device operated one-dimensionally by the target stepping motor is at the origin position; a check signal output circuit that outputs one of the rotation and reverse rotation command pulses as a check signal;
It has a flag circuit that resets the output gate signal when even one pulse of the check signal is input, an AND gate that takes the logical product of the check signal and the gate signal, an up count terminal, a down count terminal, and a reset terminal. One of the forward and reverse command pulses is applied to one of the up-count and down-count terminals, the other of the forward and reverse command pulses is applied to the other of the up-count and down-count terminals, and the AND is applied to the reset terminal. a counter that inputs the output of the gate, counts up and down the input pulses of the up-count and down-count terminals, and outputs a count value; and a latch circuit that latches the count value by the check signal. A stepping motor malfunction detection circuit comprising:
