Encoder Monitoring off (Alarm Off)
Encoder monitoring A Monitoring on (Alarm On)
Axis display A Display measured position
( Axis) Do not display measured position /
no encoder
Function of Resets display to zero
CL key Does not reset display to zero
1) Calculate the entry value for P41
Example: Displayed measuring length La = 620.000 mm
Actual length (determined with, for example, the VM 101 comparator
system from HEIDENHAIN) Lt = 619.876 mm
Length difference
∆
L = Lt – La = –124 µm
Compens. factor k: k =
∆
L / La = –124 µm / 0.62 m = –200 [µm/m]
