Title:
MOTOR DRIVE CONTROL DEVICE AND MOTOR DRIVE CONTROL METHOD
Document Type and Number:
Japanese Patent JP2022161590
Kind Code:
A
Abstract:
To provide a technique capable of properly driving a plurality of motors using an encoder signal.SOLUTION: A plurality of motor units 1071, 1072 includes DC motors 1051, 1052 and encoders 1061, 1062 of the DC motor, respectively. Drive control means 1020 receives an output of a drive control signal of the DC motor and an encoder signal of the encoder of the driven DC motor. Switching means 1030 selectively switches the motor unit connected to the drive control means so as to enable communication of the drive control signal and the encoder signal from among the plurality of motor units. When the switching means switches the motor unit to be connected to the drive control means, position information is stored at the time when the motor unit stops that is connected to the drive control means before switching and a drive control signal is output based on the position information when operation of the DC motor of the reconnected motor unit is restarted.SELECTED DRAWING: Figure 6
