Abstract

PURPOSE:To simplify a facility modifying work required for sequential starting of plural electric motors and also to reduce length of time required therefor, by changing timing of command for 'Starting' from Timing 2 to Timing 3. CONSTITUTION:When an 'Operation Command' S is put into a pulse generator 10, 3 different timing pulses (b)-(d) are made available by a pulse divider 20. As these timing pulses are impressed to output units 30, 40 and 50, 'Starting Commands' A2-C2 are formed. All the starting commands are given to electric motors M1-M4 in turn, and in this fashion, sequential starting of plural electric motors can be achieved with a simple device.
