In order to adjust the current controller gain to the inductance change, additionally
function "sat L on I control" must be activated in ds04 (=> Current control Chapter
6.2.6).
Cogging torque compensation (SM)
Harmonics occur at some synchronous machines and linear drives due to fluctua-
tions of the magnetic flux. This leads to the ripple of the motor torque at constant
load or no-load operation. This superimposed torque is named cogging torque or
"cogging". For motors with (approximately) periodic process of the cogging torque
whose compensation is possible.
Parameterization of the compensation
Maximum four sine-wave generators can be parameterized via parameters mo17
frequency factor mo18 magnitude and mo19 phase. The compensation torque is
created by overlaying of the sine waves.
