HEIDENHAIN | ND 7000 | Operating Instructions Milling | 01/2020
Explanation
Activation of offset calculation between reference mark and
datum of the machine
Setting range: ON or OFF
Default value: OFF
Manual input of the offset (in mm or degrees according to the
selected encoder type) between reference mark and datum
Default value: 0.00000
Apply applies the current position as an offset (in mm or
degrees, depending on the selected encoder model) between
the reference marks and zero point
Explanation
Mechanical influences on the axes of the machine are compen-
sated
Settings:
ON: Compensation is active
OFF: Compensation is not active
Default value: OFF
If Compensation is active, the Nominal length and
Actual length cannot be edited or generated.
Input field for the length of the calibration standard according to
the manufacturer's specifications
Input: Millimeters or degrees (depending on the encoder)
Input field for entering the measured length (actual distance
traversed)
Input: millimeters or degrees (depending on the encoder)
