Document Type and Number:
Japanese Patent JP6546231
Kind Code:
B2
Abstract:
In a method of controlling a rotary table device, a clamp mechanism drive unit is controlled to unclamp a brake disk. Thereafter, a pressure of working fluid supplied to an unclamp fluid chamber is decreased, and a motor drive unit is controlled to rotate a motor.
