14.3 Machine zero point and 2nd, 3rd, 4th reference points (Zero point)
Function and purpose
The machine zero point serves as the reference for the basic machine coordinate system. It is
inherent to the machine and is determined by the reference (zero) point return.
2nd, 3rd and 4th reference (zero points) points (zero points) relate to the position of the
coordinates which have been set beforehand by parameter from the zero point of the basic
machine coordinate system.
