Using an Angle encoder as linear encoder
Certain parameters must be taken into account when configuring an angle encoder
or rotary encoder as a linear encoder, in order to prevent an overrun of the system.
The mechanical ratio must be chosen such that the maximum traverse range of
21474.483 mm is not exceeded
The reference mark shift should only be used when considering the maximum
traverse range of ±21474.483 mm, since this limit applies both with and without
a reference mark shift
Only for multiturn rotary encoders with EnDat 2.2: the rotary encoder must be
mounted such that an overrun of the rotary encoder does not affect the machine
coordinates negatively

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
mark and the zero point
