870 HEIDENHAIN Technical Manual MANUALplus 620
Machine type 1:
The machine is commissioned as usual until the k
V
factor is to be
determined.
Enter MP_compIpcT1 = 1 and MP_compIpcT2 =0.
Increase the k
v
factor (MP_kvFactor) until you reach the oscillation limit.
Starting value:
Change MP_compIpcT2 until you have found the maximum k
v
factor. If you
cannot find a maximum k
v
factor, use the default value.
Starting value:
Increase MP_compIpcT1 until you have found the maximum k
v
factor. If the
value found is significantly greater than the starting value (> factor 2), you
should adjust MP_compIpcT2 again by enlarging and reducing it to find the
optimum value.
Machine type 2:
The machine is commissioned as usual until the k
V
factor is to be
determined.
Enter MP_compIpcT1 = 1 and MP_compIpcT2 =0.
Increase the k
v
factor (MP_kvFactor) until you reach the oscillation limit.
Starting value:
Change MP_compIpcT2, normally by reducing it, until the following error is
at its minimum.
