Encoder Connection For Motors Without Drive-Cliq Interface; Incremental Encoder Sin/Cos 1 Vpp - Siemens SIMOTICS T-1FW3 Configuration Manual

Cables
For all encoder types (incremental encoder, absolute value encoder and Resolver) the same
DRIVE-CLiQ cables can be used between the motor and converter:
Table 4- 4
6FX
Only prefabricated cables from Siemens (MOTION-CONNECT) may be used.
For other technical data and length code, refer to Catalog D21.4, Chapter "MOTION-
CONNECT connection system".
4.1.2.3

Encoder connection for motors without DRIVE-CLiQ interface

For motors without an integrated DRIVE-CLiQ interface, the analog encoder signal in the
drive system is converted into a digital signal. For these motors as well as external encoders,
the encoder signals must be connected to SINAMICS S120 via Sensor Modules.
4.1.2.4

Incremental encoder sin/cos 1 Vpp

Description
This encoder senses relative movements and does not supply absolute position information.
In combination with an evaluation logic, a zero point can be determined using the integrated
reference mark, which can be used to calculate the absolute position.
The encoder outputs sine and cosine signals. These signals can be interpolated using
evaluation logic (usually 2048x).
The direction of rotation can be evaluated using the encoder.
In the version with DRIVE-CLiQ interface, this evaluation logic is already integrated in the
encoder.
Function and technical data
● Angular measuring system for the commutation
● Speed actual value sensing
● Indirect incremental measuring system for the position control loop
● One zero pulse (reference mark) per revolution
