5. Evaluate the step response:

6. Change the gain Vp under C00075

and the reset time Tn under C00076.

7. 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.

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

="0:

Test mode deactivated").

9. If the Imin control is used, both calculated controller parameters can also be used for the

Imin controller:

• C00075

 C00958 (Imin controller: gain)

• C00076

 C00959 (Imin controller: reset time )

10. Save parameter set (C00002

= "11: Save start parameters").
