Abstract
PURPOSE: To let the stop timings of plural motors be accurately determined by starting delay means by the power feed release signal of the motor of the preceding order and starting the power feed of the motor of the succeeding motor upon completion of the specified delay time.
CONSTITUTION: When a power feed switch S1 is turned off upon arrival of the time for starting the succeeding order motor M2 when the running of the precedent order motor M1 is stopped, transistors Tr1, Tr2 conduct owing to the rise of their base potentials and Tr1 conducts as well. Because of this, a short circuit by the motor M1 and Tr1 is perfected to apply electric brake to the motor M1. At this time, Tr4 becomes non-conducting owing to conducting of Tr3 and therefore charging in a capacitor C is started from this time and when the terminal voltage thereof reaches the specified value, Tr5, Tr6 conduct to operate a relay RL. As a result of this, the select switch S2 for the motor M2 changes over to the ground side to flow drive current to the motor M2, then the motor 2 starts running.
