7. Enter the Vp values in per cent from the grid points into the subindices of object 0x2C04 (or
0x3404 for axis B):
[5-6] Grid point values of the saturation characteristic determined
8. Enter the maximum process current ("15 A") as maximum current in object 0x6073 (or 0x6873
for axis B).
• With these settings, the same current characteristic should occur, irrespective of the current
magnitude.
• Since the current controller gain is now corrected actively, the step responses may differ
slightly compared to the previous measurements. In this case, the current controller
parameters must be optimised one last time.
9. For permanent storage: Upload the detected characteristic from the i700 servo inverter into the
Controller.
The »EASY Starter« serves to save the parameter settings of the i700 servo inverter as parameter
file (*.gdc). In the »PLC Designer«, this file can then be imported in the corresponding axis.
