Abstract:
A servo motor controller includes: a servo motor; a driven member which is driven by the servo motor and in which a load acting on a drive axis is varied depending on the position of the driven member; a position detection portion and a speed detection portion for the driven member; and a motor control portion, where the motor control portion includes: a position control portion which calculates a speed command based on a positional error between a position command for the driven member and the position FB; a speed control portion which calculates a torque command by multiplying a speed error between the speed command and the speed FB by a speed gain and/or adding a torque offset to the speed error; and a change portion which changes at least one of the speed gain and the torque offset according to the position of the driven member.

Claim (Index 1):
A servo motor controller comprising: a servo motor;\n a driven member which is driven by the servo motor and in which a load acting on a drive axis is varied depending on a position of the driven member; a position detection portion which detects the position of the driven member; a speed detection portion which detects a speed of the driven member; and a motor control portion which controls the servo motor, wherein the motor control portion includes: a position control portion which calculates a speed command based on a positional error between a position command for the driven member and position feedback detected by the position detection portion; a speed control portion which calculates a torque command by multiplying a speed error between the speed command calculated by the position control portion and speed feedback detected by the speed detection portion by a speed gain and/or adding a torque offset to the speed error; and a change portion which changes at least one of the speed gain and the torque offset according to the position of the driven member.
