SIMOTION D4x5‑2 module replacement without PG/PC
To enable a module replacement without a PG/PC, you must back up the current non-volatile
SIMOTION and SINAMICS data on the CF card during operation.
NOTICE
Loss of data due to failure to make backup copies
Non-backed-up non-volatile SIMOTION data can be lost on hardware replacement (module
defect), for example, if the current value of the retain variables have not been backed up and
replaced by their initial values again.
Back up the non-volatile SIMOTION data on the CF card.
NOTICE
Repeat referencing necessary after absolute encoder overflow
If an absolute encoder overflow occurs after _savePersistentMemoryData, the actual position
value is no longer correct after the non-volatile SIMOTION data are restored.
In this case, homing (absolute encoder adjustment) must be repeated.

Replacing DRIVE-CLiQ components
Module replacement
DRIVE-CLiQ components not only support replacement in the switched-off state of the
machine/system (Power Off), but also a replacement during operation. For this, the component
to be replaced must be at the end of the DRIVE-CLiQ line.
Requirement
● The affected components are located at the end of the line.
● If an infeed is affected, the power units supplied by it do not function.
