Encoderless SLS or SS1-r
Safely-limited speed (SLS) without encoder includes the following subsystems: FSO
encoderless speed measurement, FSO Digital input, FSO Logic (1 or 2), FSO STO
output, FSO digital output (optional), and Drive STO. Block diagram is equal to SS1-r
function.
SLS with encoder, SDI and SS1-r
