Brief Description
1
Function
The "Reference Point Approach" function is used to synchronize the measuring system of a
machine axis with machine zero. The machine axis is traversed to machine zero and the
measuring system set to zero.
If it is not possible to approach machine zero directly, a reference point within the traversing
range of the machine axis is used whose position with reference to machine zero precisely
known.
After the reference point approach, the measuring system of the machine axis is not set to
zero but to the corresponding reference point value.
Measuring systems and referencing methods
The "Reference point approach" function enables machine axes to be referenced using the
following measuring systems and referencing methods:
•
Measuring systems
–
Incremental rotary measuring system with at least one zero mark
–
Incremental linear measuring system
–
Rotary measuring system with distancecoded reference marks (supplied by
Heidenhain)
–
Linear measuring system with distancecoded reference marks (supplied by
Heidenhain)
–
Absolute rotary measuring system
–
Absolute linear measuring system
•
Referencing methods
–
Referencing with incremental measuring systems with BERO and one-edge and two-
edge detection
–
Referencing with incremental measuring systems with replacement of homing cam
with BERO
–
Referencing with incremental measuring systems with BERO with configured
approach velocity for spindle applications
–
Referencing with measuring systems with distancecoded reference marks by
overtravelling 2 or 4 zero marks
–
Referencing of passive measuring systems using measuring system adjustment
–
Referencing in followup mode
–
Referencing with cam switch at the drive
