6. Evaluate the step response:

7. Change the gain Vp under C00075

and the reset time Tn under C00076.

8. Repeat steps 4 ... 6 until the optimum step response of the motor current is reached.

• In the optimised state the current rise time typically is 0.5 ... 1 ms.

• If the adjustment results are not satisfactory, the decoupling network can be

additionally activated via the setting C00074

= "1". After this, repeat the steps 2 ... 6.

• In case of MCS, satisfying results may only be achieved with a current-dependent

correction of the current controller parameters based on the saturation behaviour of the

motor stator leakage inductance. For this purpose, it is required to use a motor with an

electronic nameplate (ENP) or to set the saturation characteristic manually.Correction

of the stator leakage inductance... ( 201)

9. After the optimisation has been completed, deactivate the test mode again (C00398

="0:

Test mode deactivated").

10. Save parameter set (C00002

= "11: Save start parameters").
