Abstract
A first judgment circuit and a second judgment circuit are adapted to set a judging signal high when a judgment data sent from a microprocessor indicates failure. The high level judging signal triggers a forced idle command connected to a motor driver, to be high level whereby the motor is forcibly suspended. Subsequently, when a reset command is accidentally transmitted by the microprocessor due to an unexpected fault, a first judging signal from the first judgment circuit is reset to low level. However, a second judging signal from the second judgment circuit remains high level. As a result, the forced idle command stays high level.
