Title:
SIMULTANEOUS UNIAXIAL POSITIONING CONTROL UNIT
Document Type and Number:
Japanese Patent JPS5578307
Kind Code:
A
Abstract:
PURPOSE:To obtain a simultaneous uniaxial positioning control unit which can control servo motors in respect to all axes, by providing only one amplifier which regulates a loop gain and only one limiter for limiter level regulation. CONSTITUTION:Resistances R1-Rn for gain regulation and limiter level regulating elements 11-1-11-n are connected to amplifier 4 and limiter circuit 5 in control circuit through switches 10-1-10-n and switches 12-1-12-n respectively. When a command input and a control axis selection signal are applied to control circuit 1 for the purpose of controlling one of servo motors 3-1-3-n, the output of decoder 13 closes one of switches 10 and 12 to select one of servo motors 3 through switch switching control part 14 and switch circuit 2. Thus, servo motors are operated by a prescribed loop gain and a prescribed limiter level.
