HEIDENHAIN ND 710 v.3 - Manual (Page 37)

38
Operating
Parameters
P41.1 to P41.3 Linear axis error compensation
Input range (µm): -99999 to +99999
Factory 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 DL = L a – L d = – 124 µm
Compensation factor k:
k = DL/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).
