Abstract
To provide a controller capable of exerting acceleration/deceleration control more accurately than has been exerted conventionally and capable of reducing the occurrence of shock and shortening cycle time. A numerical controller outputs a movement command for a drive axis of a machine based on a command in a program for controlling the machine having the drive axis controlled by a servo motor. The numerical controller exerts acceleration/deceleration control over the drive axis so as to satisfy a condition for the acceleration/deceleration in each of a machine coordinate system as an orthogonal coordinate system in the machine and a drive axis coordinate system by normalizing each of acceleration/deceleration related information in the machine coordinate system and acceleration/deceleration related information in the drive axis coordinate system to a value in the drive axis coordinate system.
