Example of Absolute Encoder Adjustment
In the example, the following is assumed:
•
Reference-point coordinate = -125 mm
•
Working range of SSW_STRT = -1000 mm to SSW_END = 1000 mm
•
Absolute encoder adjustment = 0
•
Encoder range = 2048 increments (= pulses) with a resolution of
1 mm/increment
•
The absolute encoder used cannot be exactly adjusted mechanically and also
does not have the option of setting the actual value.

1) Correlation between the coordinate system and encoder values with the set absolute
encoder adjustment. The encoder value 0 corresponds to the actual value -125.
Required correlation of the coordinate system with the encoder. At this position the
coordinate should be -125.
