8. After the optimisation has been completed with C00398 = "0", deactivate the test
mode for the current controller again.
9. Save parameter set (C00002
= "11").
5.1.11.1 Correction of the leakage inductance via saturation characteristic
The current controller must be adjusted to the electrical characteristics of the motor –
stator resistance and stator leakage inductance:
In case of modern motors, however, the stator leakage inductance changes (C00085) as a
function of the magnitude of current so that each current value requires a new current
controller setting.
When the motor is operated with very low and very high currents (e.g. in Pick and place
applications), it is not always possible to achieve a satisfactory current controller setting
for all operating points. For this purpose, the correction of the leakage inductance and
current controller parameters is possible via a saturation characteristic that can be set in
C02853 (17 base points).
