Control with following error (servo lag):
The adjusted maximum jerk works during operation with following error.
MP1090 is not changed.
Procedure:
Check the temporary input values for the machines parameters

Specify the k factor for the machining feed rate:

v
Enter the following test program:

LBL1
L X<maximum traverse> R0 F<machining feed rate>
L X0 R0 F<maximum machining feed rate>
CALL LBL1 REP 100/100
Display the actual feed rate (v actual) with the internal oscilloscope.

Start the test program with feed-rate override = 100 %.

Increase the value in MP1810.x up to the oscillation limit.

Calculate MP1810.x:

MP1810.x = <determined value> · 0.6
MP1810.x at the oscillation limit
For axes that are interpolated with each other, the k
The axis with the smallest k
You can save a number of different k
