2.7 Measuring reference system
2.7.1 Basic concepts
Homing
During homing, the position of the axis zero point AZ is determined.
Stop point BZ (block zero)
A fixed point in the origin of the selected coordinate system, which is travelled to in homing.
Movement to zero
After the stop point BZ is reached, the drive is travelled to at a defined distance in order to reach the
axis zero point AZ.
Axis zero point AZ (Axis Zero)
It is shifted by a defined distance from the stop point BZ in the origin of the selected coordinate sys­
tem. This distance is established with 1.2 mm each in the direction of the X- and Y-axis.
The software end positions and the project zero point PZ refer to the axis zero point AZ.
Project zero point PZ (Project Zero)
is a point to which the actual position and the absolute target positions from the position record table
refer. The project zero point is shifted by a defined distance from the axis zero point AZ.
Software end positions SLN (Software Limit Negative)/SLP (Software Limit Positive)
Limit the effective stroke in the direction of the X- or Y-axis. If the target position of a positioning job is
outside the software end positions, the positioning job is not executed and a malfunction is reported.
Usable stroke
The distance of the software end positions in the direction of the X- or Y-axis. Maximum stroke by
which the planar surface gantry can travel in the corresponding direction.
Increments
The controller works in the range of the drive controller with encoder increments (EINC). In contrast,
so-called interface increments (SINC) are used at all user interfaces and in the field of internal data
management.
