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
v
factor for the machining feed rate:
 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
For axes that are interpolated with each other, the k
v
factors must be equal.
The axis with the smallest k
v
factor defines the input value for all axes.
You can save a number of different k
v
factors in the iTNC (MP1815.x) and
activate them with M functions (see “The control loop" on page 810).
Procedure for defining a characteristic curve kink point:
 k
v
factor for rapid traverse (characteristic curve kink point):
MP1820.x = 1
MP1810.x at the oscillation limit
MP1830.x =
Max. contouring feed rate · 100 %
