Title:
CONTROL CIRCUIT FOR SLOW ACCELERATOR
Document Type and Number:
Japanese Patent JPS60160388
Kind Code:
A
Abstract:
PURPOSE:To smoothly switch from a slow accelerator control to a normal control by sequentially selecting resistors for dividing the voltage supplied to a motor. CONSTITUTION:A decoder 8 outputs a selection signal synchronized with the period of a pulse outputted from an oscillator 11. A control switch 9 for selecting resistors for dividing the voltage eM to a motor is sequentially controlled by a selection signal from the decoder 8. A differential amplifier 2 compares the partial voltage ei2 with a reference voltage ei1 and outputs a control voltage e0. Thus, the operation shifting from the slow accelerator control to the normal control is smoothly performed.
