Abstract
PURPOSE: To detect an abnormality quickly by setting the position error to the value proportional to the machine speed.
CONSTITUTION: The error counter 4 provides a position error PE which is determined by both a move command from the arithmetic and control unit 3 and the position detection signal Fb. (R1.PE+α1) and (R2.PE+α2) are set in the reference registers 16 and 17 respectively. (R1<R2, α1<α2, PE=V/WC, V; feed speed of machine, WC; gain of servo system). When the position error of error counter 4 increases and reaches a set value of the reference register 16, an error limit signal El which stops the command of arithmetic and control unit 3 is emerged, and when the position error increases further and reaches a set value of the reference registe 17, a put-out signal Pu is fed to the emergency stop circuit 11 to halt the numerical control unit.
