Linear Encoders
Linear Encoders
Setting the display step with linear encoders
The display step depends on the:
• Subdivision (P32)
• Counting step (P33)
• Decimal places (P38)
Example
Linear encoder with signal period 10 µm
Required display step .............. 0.000 5 mm
Subdivision (P32) ..................... 20
Counting step (P33) ................. 5
Decimal places (P38) ............... 4
The tables on this page and the next pages will help
you selecting your parameters.
