NOTICE
Too high an encoder speed can falsify a position value
The function of an axis technology object is based on the assumption that an SSI absolute
encoder never changes by more than half the value range within one module cycle
Ensure that this condition is always met when configuring your system.
Non-isochronous mode: 500 μs; isochronous mode: PROFINET cycle time
