Abstract

PURPOSE:To perform the minute positioning due to an inching operation, by synchronizing the timing of the rise of a relay with the zero crossing point of the period in an AC input. CONSTITUTION:Terminals R, S, and T are connected to a three-phase AC power source and are connected to a driving source M of a microinching device through lines lR, lS, and lT respectively. A relay MSF for normal rotation and a relay MSR for reverse rotation are provided as switches, which are operated in accordance with a control means for control of power supply/break to the driving source M on each of lines lR, lS, and lT. A moving material is positioned minutely by the detection of a zero crossing point due to a control part CO for control of relays MSR and a pulse counter.
