Title: Driving device for step motor
Inventor: TSUKAHARA AKIHIKO
IPC: H02P8/16
Filed: 1981-11-11
Abstract: PURPOSE:To improve the power efficiency of a step motor by controlling the exciting current by the reference voltage made of high and low level binary values, thereby reducing the consumed power. CONSTITUTION:A reference voltage generator 21 outputs a binary reference voltage to become high level during the prescribed period synchronously with the exciting signal of a field coil 28 and to become low level after the prescribed period. An exciting current detector which includes an exciting current detedting resistor R8 produces the detected voltage in response to the exciting current of a field coil 28. A comparator 24 compares the detected voltage with a reference voltage, thereby controlling a chopper circuit which includes a chopper transistor 27 by the output signal of the comparator. Since the exciting current of a step motor field coil 28 is controlled in response to the reference voltage made of high and low binary values, the current at the time of holding the position can be sufficiently reduced.

Abstract: PURPOSE:To improve the accuracy of fault detection, to reduce required time and to improve reliability by deciding a second fault state for which abnormality detection is detected in the prescribed number of times of trips. CONSTITUTION:Whether or not an engine cooling water temperature transmitted from a water temperature 22 through an input interface circuit 13 and an A/D converter 14 is within a prescribed range is decided first. When it is decided that the water temperature is not within a normal range, whether or not the value of a TIMER exceeds one second is decided.

Then, when the abnormality is detected continuously while the value of the CNT1 is more than two, that is for more than two trips, storage is performed as 'a complete fault'. Also, when the abnormality is detected while the value of the CNT2 is more than 10, that is, when the abnormality is detected in the trips of cumulative 10 times even when the abnormality is not detected in the consecutive trips, the storage is performed as 'an incomplete fault'.
