Abstract
A method is provided for adapting controller parameters of a drive to different operating states. A control loop includes a PID controller whose I gain factor is adapted to a drive velocity and/or whose D gain factor is adapted to a drive current, and consequently to a drive load. The I gain factor is determined based on the drive velocity and the D gain factor is determined based on the drive current, in each case at least in one area, the I gain factor falling with the drive velocity and the D gain factor rising with the drive current.
