The reference mark search does not need to be performed for serial
encoders with EnDat interface, because the axes are automatically
homed.
Explanation
Definition of the type of reference mark
Settings:
None: There is no reference mark
One: The encoder has one reference mark
Coded: The encoder has distance-coded reference marks
Default value: One
For linear encoders with coded reference marks:
maximum traverse path for determining the absolute position
Setting range: 0.1 mm ... 10000.0 mm
Default value: 20.0
For angle encoders with coded reference marks:
maximum nominal increment for determining the absolute
position
Setting range: > 0° ... 360°
Default value: 10.0
Specifies whether the reference mark pulses are evaluated in
inverted form
Settings
ON: Reference pulses are evaluated in inverted form
OFF: Reference pulses are not evaluated in inverted form
Default value: OFF
Configuration of the offset between the reference mark and the
zero point
