Encoder With Htl Level At Di1/Di2 - Lenze 8400 StateLine C Reference Manual

5.10.3

Encoder with HTL level at DI1/DI2


Note!
At the digital terminals DI1 and DI2, only encoders with HTL level can be used.
In spite of the selected operating mode without encoder feedback, the actual
speed value (C00051) is calculated if an encoder is connected and "1: Encoder
signal FrqIn12" is selected in C00495.
Low speeds (except for edge counting)
For the first method
the encoder resolution.
The quantisation error
 is independent of the encoder resolution,
 exclusively depends on the encoder quality (encoder errors).
 at least amounts to 0.5 rpm.
For a maximum dynamic performance, the scan time is automatically kept at the
minimum value required through internal arithmetic operations.
