Motor encoder

The motors are equipped with various encoder systems for rotor position and
speed sensing.
Reference:
1FT5 motors can be optionally ordered with a mounted or integrated encoder
system for position sensing.
Table 3-1 shows the assignment of SIMODRIVE units to the servo/main spindle
motor types.

Indirect position and motor speed sensing

The various possibilities for indirect position and speed sensing and for
positioning the motor shaft as a function of the drive configuration (SINUMERIK,
SIMODRIVE and motor) are listed in Tables 3-2 and 3-3 (Section 3.5).
Direct position sensing

Encoder systems which can be evaluated

The various possibilities for direct position sensing to position as a function of
the drive configuration (SINUMERIK, SIMODRIVE and motor) and the encoder
system used are listed in Tables 3-4 and 3-5 (Section 3.5).
We recommend that measuring systems with sinusoidal voltage signals are
used due to the higher data transmission reliability and integrity.
