4 Description of the SINUMERIK 810D
4.3 Measuring system
Direct
The motor measuring system is only used to detect the motor position. If ne-
measuring system cessary, a second measuring system, e.g. a rotary position inducer, can be
used for position sensing at the load end.
MSD
Only encoders with voltage signals can be used with the SINUMERIK 810D.

M: Max. possible measuring steps
G: Accuracy of the encoder system
M = 128 per encoder signal
period or graduation
G is a function of the accuracy of the
optional encoder system.
M = 128 V Z per 360 degrees mech.
