II - 3 Encoders and Measured Value Display
Setting the display step with angle encoders
With angle encoders, the display step depends on the
• line count of the encoder (P35.*) and the
• angle subdivision (P36.*)
Both parameters are entered separately for each rotary axis.
The angle subdivision can range from 0.2 to 100 depending on the
line count of the encoder.
