Replacing Drive-Cliq Components - Siemens SIMOTION D410 Series Commissioning Manual

Maintenance and service
5.2 Replacing modules (spare part scenario)
Replacing SIMOTION D410 modules without PC/programming device
To enable a module replacement without a programming device/PC, you must back up the
current non-volatile data to the CompactFlash Card.
The user program can use the "_savePersistentMemoryData" system function to save the
contents of non-volatile data to the CompactFlash Card. This ensures that the retain
variables and the absolute encoder position are backed up to the CompactFlash Card in the
event that a spare part is fitted.
As an additional option, you can back up the non-volatile data by setting the service selector
switch or by using IT DIAG; for details, refer to the section titled Diagnostic data and non-
volatile data (Page 172).
Note
Non-volatile data that are not backed up to the CompactFlash Card will be lost if a spare part
is installed (in the event of a module defect). (For example, failing to back up the current
values of the retain variables will result in them being lost and reset to their initial values).
If an absolute encoder overflow occurs after "_savePersistentMemoryData", the actual
position value will no longer be correct once the non-volatile data have been restored. In this
case, homing (absolute encoder adjustment) must be repeated.
