4 Description of the SINUMERIK 810D
4.3 Measuring system
Direct
The motor measurement system is used for sensing the motor position. A se-
measuring system cond measuring system, e.g. a rotary transducer, can be used for load-side
position sensing if necessary.
MSD
In the case of SINUMERIK 810D only encoders with voltage signals can be
used.

M: Max. possible measuring steps
G: Accuracy of the encoder
system
M = 128 per encoder signal
period or lattice pitch
G is a function of the accuracy of the
optional encoder system.
