Document Type and Number:
WIPO Patent Application WO/2021/149194
Kind Code:
A1
Abstract:
A motor control device (101) controls a master motor (4A) and a slave motor (4B) for driving one object (14) to be driven and is provided with: a master axis control unit (25A) for controlling the master axis (6A) of the master motor (4A) having a first motor characteristic value; and a slave axis control unit (25B) for controlling the slave axis (6B) of the slave motor (4B) having a second motor characteristic value. The master axis control unit (25A) drives the master motor (4A) using a first current command for controlling the speed of the master motor (4A). The slave axis control unit (25B) calculates, on the basis of a value obtained by multiplying the first current command and a first ratio that is the ratio of the second motor characteristic value to the first motor characteristic value, a second current command for controlling the speed of the slave motor (4B) and drives the slave motor (4B) using the second current command.
