SINUMERIK 810D Equipment Manual Configuration CCU (PHC) – 03/2006 Edition
The motor measurement system is used for sensing the motor position. A se-
cond measuring system, e.g. a rotary transducer, can be used for load-side
position sensing if necessary.
In the case of SINUMERIK 810D only encoders with voltage signals can be
used.
