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 scale, can be used for load-side position
sensing if necessary.
FSD
Incremental encoders, distance-coded incremental encoders, or EnDat absolute
value encoders can be used (voltage signals).

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
load-side encoder system.
M = 128 or 2048 for
611D convenience control
per encoder signal period or
lattice pitch
G is a function of the accuracy of the
load-side encoder system.
M = 128 per encoder signal
period or lattice pitch
G is a function of the accuracy of the
optional encoder system.
