P41.1 to P41.3 Linear axis error compensation
Linear axis error compensation is activated via parameters
40.1 to 40.3.
Input range
[µm] : – 99999 to + 99999
Default setting: 0
Example: Displayed length Ld = 620.000 mm
Actual length (as determined for example with
the VM 101 from HEIDENHAIN)
La = 619.876 mm
Difference
∆L = La – Ld = –124 µm
Compensation factor k:
k =
∆L/Ld = –124 µm/0.62 m = –200 [µm/m]
P42.1 to P42.3 Backlash compensation
Input range (mm): +9.999 to -9.999
Default setting: 0.000 = no backlash
compensation
A change in direction might cause a clearance between
rotary encoder and table. This is referred to as backlash.
Positive backlash: The rotary encoder is ahead of the table.
The distance traversed by the table is too short (entry of
positive value). Negative backlash: The rotary encoder
follows the table. The distance traversed by the table is too
large (entry of negative value).
