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
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
confusion and rule out programming errors.
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.
