5.9.3 Encoder with HTL level at DI1/DI2
Low speeds (except for edge counting)
For the first three methods (C00496
= 0, 1, or 2), the minimum speed that can be measured
depends on the number of increments of the encoder.
The quantisation error
 is independent of the encoder PPR.
 exclusively depends on the encoder quality (encoder errors).
 is minimally 0.5 rpm.
For a maximum dynamic performance, the scan time is automatically kept at the
minimum value required through internal arithmetic operations.
 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
.
