11.1.1 Notes on replacing units
The MOVIPRO
®
unit allows for a quick unit replacement. The MOVIPRO
®
unit is
equipped with a replaceable memory card on which all unit data can be stored.
If a unit has to be replaced, the plant can be started up again quickly by simply re-plug-
ging the memory card.
After the startup procedure, you have to download the unit data to the memory card.
11.1.2 Replacing units
Proceed as follows to replace the MOVIPRO
®
:
1. Perform a data backup now if you are not certain whether the current unit parame-
terization is stored on the SD card.
2. Disconnect the MOVIPRO
®
unit from the power supply and remove it from the sys-
tem.
3. Remove the memory card of the unit via the service cover plate on the MOVIPRO
®
housing cover.
4. Insert the memory card into a new MOVIPRO
®
unit via the service cover plate.
5. Install the new MOVIPRO
®
unit in the system and connect it to the power supply.
INFORMATION
Observe the following notes when replacing a unit:
• Only insert the memory card when the MOVIPRO
®
unit is switched off.
• After the replacement, the parameters last saved on the SD card are used.
• If an absolute encoder is used as motor encoder or synchronous encoder, you
have to perform a reference travel during initial startup or after a unit or encoder
replacement.
• If you an encoder with HIPERFACE
®
interface, a unit or encoder replacement is
detected automatically and the "IPOS reference" is reset.
• If you use an encoder with SSI interface, you have to adapt the encoder position
to the mechanical plant conditions via a reference travel.
