2.12 Selection and configuration of encoders
Commissioning encoders with a DRIVE-CLiQ interface
For DRIVE-CLiQ encoders, the properties of a rotary absolute encoder are identified with the
following parameters of the Control Unit:
● p0404[0..n] Encoder configuration active
● p0408[0..n] Rotary encoder pulse number
● p0421[0..n] Absolute encoder rotary multiturn resolution
● p0423[0..n] Absolute encoder rotary singleturn resolution
This data is pre-assigned according to the preset codes in p0400 (encoder type selection)
from the encoder lists. Parameters p0404, p0408, p0421 and p0423 are checked by the
Control Unit when booting.
Alternatively the data can be read out from the encoder with the setting p0400 = 10000 or
p0400 = 10100 (identify encoder). If the encoder data read out matches a known encoder
type, this code is entered in p0400 using the Control Unit. Otherwise the general code p0400
= 10050 (encoder with EnDat interface identified) will be entered.
A DRIVE-CLiQ encoder is identified by the parameter p0404.10 = 1.
For DRIVE-CLiQ encoders, encoder codes are defined respectively for parameter p0400
(see SINAMICS S120/S150 List Manual and above table).
If the Control Unit identifies a DRIVE-CLiQ encoder type for which no code is stored, during
identification it enters the code p0400 = 10051 (DRIVE-CLiQ encoder identified).
The data is also automatically identified if a DRIVE-CLiQ encoder is found during automatic
commissioning. During identification, the Control Unit reads out the values for p0404, p0421
and p0423 from the DRIVE-CLiQ encoder. The Control Unit uses this data to determine the
contents of p0400. The newly defined codes are not stored in the DRIVE-CLiQ encoder.
Replacing a SINAMICS Sensor Module Integrated
If a defect occurs in a SINAMICS Sensor Module Integrated (SMI) or in a DRIVE-CLiQ
Sensor Integrated (DQI), contact your local Siemens office for a repair.
