Title:

STEPPING MOTOR CONTROLLER

Document Type and Number:

Japanese Patent JP3480349

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To reduce the capacity of a memory part necessary for driving data, by providing a storage part of storing data by generation of driving phase signals of a plurality of control circuits controlling the movement of a plurality of stepping motors and sharing driving data.
SOLUTION: Stepping motors 16-1 to 16-n whose quantity is (n) is operationally controlled. Stepping motor control circuits 14-1 to 14-n indicate the acceleration or deceleration and positioning of the motors 16-1 to 16-n for the stepping motor driving circuits 15-1 to 15-n under the control by MPU 11. The movements of the motors 16-1 to 16-n A are controlled respectively through motor driving circuits 15-1 to 15-n. The control circuit 14-1 to 14-n produce a motor driving phase signal from slewing data or driving data consisting of timer data and movement information stored in a memory 13 and output them to the driving circuits 15-1 to 15-n respectively. Acceleration and deceleration patterns are indicated according to the rotational speed, direction, angle, and the number of stepping of the motor 16 with the driving phase signal.
