Referencing with absolute value encoders
2.6.1
Information about calibration
Machine axes with absolute encoder
The advantage of machine axes with absolute value encoder is that after a one time
adjustment procedure, the necessary reference point traversing with incremental measuring
systems (e.g. build-up of control, de-selection of "Parking" of machine axes etc.) can be
skipped and the actual value system of the machine axis can be immediately synchronized
to the determined absolute position.
Adjustment
Adjustment of an absolute encoder involves matching the actual value of the encoder with
the machine zero once and then setting it to valid.
The current adjustment status of an absolute value encoder is displayed in the following axis
specific machine data of the machine axis, to which it is connected:
MD34210 $MA_ENC_REFP_STATE (status of absolute encoder)
Value
Meaning
0
Encoder not calibrated
1
Encoder adjustment enabled
2
Encoder is calibrated
Adjustment methods
The following adjustment methods are supported:
•
Adjustment by entering a reference point offset
•
Adjustment by entering a reference point value
•
Automatic adjustment with probe
•
Adjustment with BERO
