Abstract

PURPOSE:To recover an interpolar condition rapidly by detecting the length of an interpolar clearance and changing the velocity of an interpolar servo or servo-gain based on the detected output. CONSTITUTION:A digital scale 9 is installed on an electrode support bar 10. If the electrode 1 descends, a pulse Sp in a plus direction generates. While the electrode ascends, a pulse Sn in a minus direction generates. These pulses are input to a reversible counter 11 which is an interpolar judging device and a count value of the input is converted to an analog signal by means of a digital analog converter D/A. This signal is supplied to a circuit GC, thus resulting in a change of the velocity of an interpolar servo or of a servo-gain.
