Control with following error (servo lag):
The adjusted maximum jerk works during operation with following error.
MP1090 is not changed.
Procedure:
7 7 7 7
Check the temporary input values for the machines parameters

Specify the k
factor for the machining feed rate:
v
7 7 7 7
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 (actl. speed) with the internal oscilloscope.
7 7 7 7
Start the test program with feed rate override = 100%.
7 7 7 7
Increase the value in MP1810.x up to the oscillation limit.
7 7 7 7
Calculate MP1810.x:
MP1810.x = <determined value> · 0.6
MP1810 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
activate them with M functions (See "The Control Loop" on page 6 – 109).
Procedure for defining a characteristic curve kink point:

Specify the k
factor for rapid traverse (characteristic curve kink point):
