SINUMERIK 810D Manual Hardware Configuration (PHC) -- 11.02 Edition
The motor measuring system is only used to detect the motor position. If ne-
cessary, a second measuring system, e.g. a rotary position inducer, can be
used for position s ensing at the load end.
Only encoders with voltage signals can be used with the SINUMERIK 810D.
