1. Mount the new SIMOTION D410 onto the Power Module, or onto the mounting panel (see
2. Connect all previously removed connectors.
3. Terminate the load voltage supply cables at the terminal block.
4. Rewire the shielding of all cables.
5. Insert the original CF card into the card slot of the new SIMOTION D410.
6. Switch on the power supply. The new SIMOTION D410 is immediately ready for operation.
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 SIMOTION data to the CF card.
With the _savePersistentMemoryData system function, the user program can back up the
contents of the non‑volatile SIMOTION data to the CF card. This ensures that the retain
variables and the absolute encoder position are backed up to the CF card in the event that a
spare part is fitted.
As an additional option, you can back up the non-volatile SIMOTION data by setting the service
selector switch or by using the SIMOTION IT web server; for details, see Section Diagnostic
data and non-volatile SIMOTION data (Page 203).
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.
