2.6 How do you replace the defective encoder?

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
2. Bring the motor into a no-voltage condition.
3. If necessary, allow the motor to cool down.
4. Release the encoder cable .

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.
