Linear Encoders
The ND 221 B display unit is designed for use together with
photoelectrical encoders with sinusoidal signals—11 µA
PP
.
Display step with linear encoders
You can select a specific display step by adapting the
following operating parameters:
• Signal period (P31)
• Counting mode (P33)
• Decimal places (P38)
Example
Linear encoder with a signal period of 10 µm
Desired display step ................ 0.000 5 mm
Signal period (P31) ................... 10
Counting mode (P33) ............... 5
Decimal places (P38) ................ 4
The tables on the following pages will help you to select the
appropriate parameter settings.
