User's Manual ND 281, NDP 281 - heidenhain - DR. JOHANNES ...

Parameter Settings / Function
Linear error compensation
– 99 999,9 < P41 < + 99 999,9 [µm/m]
Factory setting: 0
Example: Determine input value for P41
Displayed length ............................... Ld = 620.000 mm
Actual length (as determined,
for example, with the VM 101
comparator system
from HEIDENHAIN) ........................... La = 619.877 mm
Difference ......................................... ∆L = La – Ld = – 124 µm
Compensation factor k (= P41):
k = ∆L / Ld = – 123 µm / 0.62 m ....... k = – 198,4 [µm/m]
