To upgrade we need to:
|
|||
|
|
***
|
|||
|
|
* put all the files of the firmware on a clean SD
|
|||
|
|
* switch off the inverter
|
|||
|
|
* put the SD on the SD slot on the inverter
|
|||
|
|
* switch on the inverter
|
|||
|
|
* the inverter will start to blink red/orange
|
|||
|
|
* when it finish it will flash both leds on RED with 0,5 second pulse
|
|||
|
|
* restart the inverter
|

### Upgrading the firmware
|
|||
|
|
***
|
|||
|
|
|
|||
|
|
When upgrading the firmware, you replace the inverter firmware by a later version. Only update the firmware to a later version if you require the expanded functional scope of the newer version.
|
|||
|
|
|
|||
|
|
## Precondition
|
|||
|
|
|
|||
|
|
● The firmware version of your inverter is at least V4.5.
|
|||
|
|
|
|||
|
|
● Inverter and memory card have different firmware versions.
|
|||
|
|
|
|||
|
|
## Procedure
|
|||
|
|
|
|||
|
|
1. Proceed as follows to upgrade the inverter firmware to a later version:
|
|||
|
|
|
|||
|
|
2.
|
|||
|
|
|
|||
|
|
1. Switch off the inverter power supply.
|
|||
|
|
|
|||
|
|
2. Wait until all LEDs on the inverter are dark.
|
|||
|
|
|
|||
|
|
3. Insert the card with the matching firmware into the inverter slot until it latches into place.
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
4. Switch on the inverter power supply again.
|
|||
|
|
|
|||
|
|
5. The inverter transfers the firmware from the memory card into its memory.
|
|||
|
|
|
|||
|
|
The transfer takes approximately 5 … 10 minutes.
|
|||
|
|
|
|||
|
|
While data is being transferred, the LED RDY on the in‐ verter stays red. The LED BF flashes orange with a varia‐ ble frequency.
|
|||
|
|
|
|||
|
|
6. At the end of the transfer, the LED RDY and BF slowly flash red (0.5 Hz).
|
|||
|
|
|
|||
|
|
## Power supply failure during transfer
|
|||
|
|
|
|||
|
|
The inverter firmware will be incomplete if the power supply fails during the transfer.
|
|||
|
|
|
|||
|
|
● Start again with step 1 of the instructions.
|
|||
|
|
|
|||
|
|
7. Switch off the inverter power supply.
|
|||
|
|
|
|||
|
|
8. Wait until all LEDs on the inverter are dark.
|
|||
|
|
|
|||
|
|
Decide whether you will withdraw the memory card from the in‐ verter:
|
|||
|
|
|
|||
|
|
● You remove the memory card:
|
|||
|
|
|
|||
|
|
⇒ The inverter keeps its settings.
|
|||
|
|
|
|||
|
|
|
|||
|
|
### Firmware upgrade and downgrade
|
|||
|
|
***
|
|||
|
|
|
|||
|
|
● You leave the memory card in the inverter:
|
|||
|
|
|
|||
|
|
⇒ If the memory card still does not have a data backup of the inverter settings, in step 9 the inverter writes its settings to the memory card.
|
|||
|
|
|
|||
|
|
⇒ If the memory card already includes a data backup, the inverter imports the settings from the memory card in step 9.
|
|||
|
|
|
|||
|
|
9. Switch on the inverter power supply again.
|
|||
|
|
|
|||
|
|
10. If the firmware upgrade was successful, after several seconds the inverter LED RDY turns green.
|
|||
|
|
|
|||
|
|
If the memory card is still inserted, depending on the previous content of the memory card, one of the two following cases has occurred:
|
|||
|
|
|
|||
|
|
● The memory card contains a data backup:
|
|||
|
|
|
|||
|
|
⇒ The inverter has taken the settings from the memory card.
|
|||
|
|
|
|||
|
|
● There was no data backup on the memory card:
|
|||
|
|
|
|||
|
|
⇒ The inverter has written its settings to the memory card.
|
|||
|
|
|
|||
|
|
You have upgraded the inverter firmware.
|
|||
|
|
|
|||
|
|
## Memory cards with license
|
|||
|
|
|
|||
|
|
If the memory card includes a license, e.g. for the basic positioner, then the memory card must remain inserted after the firmware has been updated.
