Abstract
PURPOSE:To detect an abnormal state of the speed quickly by detecting the fact that the speed of a moving object is less or greater than a command value by means of a simple timer counter. CONSTITUTION:The movement command signal M is fed to the SET side and the feedback pulse PT to the RESET side in the digital timer 41. The signal CO is a count-out signal, the timer 41 provides a logical output such that CO=1 when it terminates the time count operation. When the pulse PT is fed to the timer 41 before that CO=1 holds, the timer 41 starts its time count operation again. The signal CO=1, which is fed from the timer 41, is held by the latch 42 to give an alarm output ALM. The latch 42 has an input terminal for the signal E that releases the latch signal.
