Raw Blame History

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

Firmware 13 and 14: G120c

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:

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.
