Based on the determined encoder Article number, you can directly order an encoder that has
not been written to (not loaded with data).
If you wish to order an encoder loaded with the data associated with the motor, then you
must change the last position of the Article number to "1".
Example: "6FX2001-☐☐☐☐☐-☐☐☐
0

❒
Based on the displayed encoder Article number, you can directly order an encoder that has
been loaded with the appropriate data for your motor.
Order the encoder as described in Chapter "How do you order a replacement encoder?
(Page 29) ".
This is how you determine the order number based on the subsequent tables
The encoder Article number is the order number for the encoder.
The type of encoder used is displayed in the motor Article number:
● For 1FK7 G2 and FT7 at the 14th position, e.g. 1FT7□□□-□□□□□-□C□□
● For 1FG1 at the 9th position, e.g. 1FG1□□□-□R□□□-□□□□
Note
Note regarding compatibility
Defective encoders with an "A" at the 15th position of the Article number (6FX2001
-5J□□□-
□□A
□) are replaced by an encoder with a "C" at the 15th position of the Article number
(6FX2001
-5J□□□-□□
C
□).
Example for a replacement encoder AM20DQI for 1FK7100:
The encoder with "old" Article number: 6FX2001
-5JE20-2DA1 is replaced by an encoder
with the "new" Article number: 6FX2001
-5JE20-2DC1.
You can also use
the replacement encoder with a "C" at the 15th position of the Article
number for motors with KTY84
-130 temperature sensor as well as motors with Pt1000
temperature sensor.
You can only use the replacement encoder with DRIVE
-CLiQ interface and an "A" at the
15th position of the Article number for motors with KTY84
-130 temperature sensor. These

2.5
How do you order a replacement encoder?
Note
When ordering, please observe the following:
Encoders with a DRIVE
-CLiQ interface have an electronic type plate, which contains the
specific motor and encoder data.
Do you wish to order a DRIVE-CLiQ encoder with loaded data or without data?
Encoder loaded with data
Encoder not loaded with data
Select "1" as the last digit of the Article number
for the encoder.
Select "0" as the last digit of the Article number
for the encoder.
Encoder is only designed for one motor (deter-
mined by the article number and the serial num-
ber). The encoder only functions together with
this specific motor.
The encoder can be used with various motors.
After the encoder has been mounted, the motor
can completely function.*
You must write the specific motor and encoder
data to the encoder with DRIVE-CLiQ interface.
Encoders are painted "pearl dark gray" as standard. Replacement encoders for motors with option
N16 or N40 differ from the rest of the motor regarding the paint structure and color.
NOTICE
Motor fault as a result of an excessively high temperature data
If you mount an encoder without data having been loaded to a motor with a Pt1000
temperature sensor – and use a software version SINAMICS < 4.8 or SINUMERIK < V4.8,
then the encoder outputs excessively high temperature values. The temperature monitoring
responds too early.
• In this case, use an encoder with data for your motor loaded in the factory – or program
an encoder without any loaded data as described in Chapter "How do you program an
encoder that has not been loaded with data? (Page 38)".
Data for the temperature sensor installed is stamped on the motor rating plate.
You can find additional information at Identifying the Pt1000 temperature sensor
(https://support.industry.siemens.com/cs/document/109749807/simotics%3Aumstellung-)
We recommend that you order the encoder with the appropriate loaded data as the encoder
can then be quickly and simply replaced.
You can order the encoder in 2 ways.
● You order the encoder from your local Siemens sales person.
● You order the encoder through the online spare parts service of Siemens Industry Mall
You can find details in the following sections.

2.6
How do you replace the defective encoder?
Note
When replacing a defective encoder, only use the same type of encoder. It is not permissible
to retrofit a motor with another encoder type.
Note
When several encoders are involved, only replace the encoders individually and one after
the other. In this way, you avoid interchanging encoders and using incorrect data.
Preconditions
You require:
● An encoder of the same type
● The appropriate tool for Allen screws or Torx screws
Remove the defective encoder
Procedure
1. Before removing the encoder, carefully check that the encoder and motor data have been
backed up.
You can find the motor and encoder data in directory: /user/sinamics/data/smi_data. The
backup folder is designated with c012 (12=comp.no.). The backup folder contains:
– For DQI encoders, file "dqixe1.bin" (motor data)
– For encoders with SMI, files "smi20xe1.bin" (motor data) and "smi20xe2.bin" (encoder
data)
SINAMICS SW < 4.3 / SINUMERIK SW < 4.4
SINAMICS from SW 4.3 / SINUMERIK SW
from 4.4
Before removing the encoder, backup the
data of the electronic type plate correspond-
ing to Chapter "How do you backup the data
of the electronic type plate? (Page 45)".
The encoder data are automatically backed
up when commissioning. You do not have to
manually back up the data.
2. Bring the motor into a no-voltage condition.
3. If necessary, allow the motor to cool down.
4. Release the encoder cable .

You can find information about this in Chapter "How do you program an
encoder that has not been loaded with data? (Page 38)".
* Automatic recommissioning is not possible if you do not load motor and encoder data to the encoder.
Encoder adjustment (for absolute encoder only)
Note
Only absolute encoders need to be adjusted.
When you adjust an absolute encoder, its actual value is compared once with the machine
zero point and then set to valid.
The actual adjustment status of an absolute encoder is shown in the following machine data:
SINUMERIK
For SINAMICS with EPOS
MD34210 §MA_ENC_REFP_STATE (absolute
encoder status)

2.7
How do you program an encoder that has not been loaded with
data?
Programming the encoder involves writing motor and encoder data to the encoder (the
electronic type plate).
Preconditions for writing data to the encoder
● SINAMICS firmware as of version 2.5 must be installed.
SINUMERIK firmware as of version 2.5 SP2 HF1 (essential for replaceable encoders)
must be installed.
● The motor has been commissioned.
● The electronic type plate is saved in the drive.
Note
From firmware version SINAMICS SW 4.3 /SINUMERIK SW 4.4, when being
commissioned for the first time, the motor and encoder data (the da
ta of the electronic
type plate) are automatically backed up in the appropriate drive folder.
If the data has not been backed up in the drive, there are 2 ways to do this:
•
If the component to be replaced can still be addressed via DRIVE-CLiQ, you can read
out the data from the electronic type plate and back this data up. (See Chapter "How
do you backup the data of the electronic type plate? (Page 45)")
•
If this data cannot be read out, you can call up the electronic type plate data via the
Internet. To do this, follow the procedure described in Chapter "Where can you find
the electronic type plate in the Internet? (Page 48)".
● You have replaced the defective encoder by an encoder of the same type, but not loaded
with data (the same Article number).
You can find information about this in Chapter "How do you replace the defective
encoder? (Page 34)".
Note
If you need to replace several encoders, you should always do so one at a time
to avoid
confusion and rule out programming errors.
NOTICE
Motor fault as a result of an excessively high temperature data
If you mount an encoder without data having been loaded to a motor with a Pt1000
temperature sensor – and use a software version SINAMICS < 4.8 or SINUMERIK < V4.8,
then the encoder outputs excessively high temperature values. The temperature monitoring
responds too early.
• In this case, use an encoder with data for your motor loaded in the factory – or program
an encoder that has not been loaded with data as described in the following chapters.

The backup folder contains:
– For DQI encoders, file "dqixe1.bin" (motor data)
– For encoders with SMI, files "smi20xe1.bin" (motor data) and "smi20xe2.bin" (encoder
data)
● If there are no motor and encoder data available, save the motor and encoder data
corresponding to the procedure described in Chapter "How do you backup the data of the
electronic type plate? (Page 45)".
Procedure
1. Connect the STARTER software with the SINAMICS drive system.
2. Open the appropriate project in STARTER.
3. Go "online". "Online" means that you connect STARTER with the Control Unit.
4. Switch to the "EXPERT" access level.
5. Evaluate the alarms in Starter:

How do you backup the data of the electronic type plate?
The electronic type plate data are saved to the drive. The electronic type plate is required to
program an encoder module that has not been loaded with data.
Requirements for saving the data on the electronic rating plate
● SINAMICS firmware as of version 2.5 must be installed.
● The commissioning procedure must have been completed. All component numbers must
be less than 200.
Note
From SINAMICS SW 4.3 / SINUMERIK
-SW 4.4, encoder data are automatically backed up
when commissioning.
You can find the data in directory: /user/sinamics/data/smi_data. The backup
folder is
designated with c012 (12=comp.no.).
The backup folder contains:
•
For DQI encoders, file "dqixe1.bin" (motor data)
•
For encoders with SMI, files "smi20xe1.bin" (motor data) and "smi20xe2.bin" (encoder
data)
You only have to save the motor and encod
er data as subsequently described if you found
no motor and encoder data from the defective encoder in the drive.

For SINAMICS, this is how you backup the electronic type plate data
Procedure
WARNING
Danger of death if the encoder is not properly installed or the safety devices do not work
If the encoder or any other parts of the machine are not properly installed or any safety
devices do not work, this could result in death or injury.
• Make sure all parts of the machine are correctly installed and connected.
• Make sure all safety devices are switched on again and working correctly.
1. Switch on the machine.
2. Identify the component number of the encoder module to be saved in the topology tree.
3. Write the component number of the encoder module whose electronic type plate is to be
saved to the memory card to parameter p4690.
4. To begin saving, set the p4691 parameter to "1".
→ If the operation is successful, the value of the p4691 parameter changes back to "0".
→ If the p4691 parameter changes to a value other than "0", this number will help you identify
why the write operation failed.
Note
You can find the meanings of the
parameter values in List Manual 1 as well as in the online
help.
The electronic type plate data are automatically saved to the correct path on the system card
(CF card).
You have backed up the electronic type plate data to the CF card.
