12.4 Replacing the firmware
The following section describes how to replace the firmware of an inverter.
WARNING!
Danger of injury or property damage due to unsecured loads. During the
firmware download, the control and the power unit of the inverter are
switched off. This means that unsecured loads on the drive may slip
through.
X Secure the drive load before beginning the firmware download.
NOTICE
Unexpected inverter behavior! If a firmware download is carried out, the
previously saved firmware will be deleted initially. If the firmware download
is a tear stopped too early, the inverter will not start as normal. The display
will remain empty, the LEDs will only illuminate briefly.
X Avoid any early stoppage of the firmware download.
X If an interruption took place, carry out the firmware download again and en-
sure that it completes. After this, the inverter can be operated normally.
Prerequisites:
• At least the control unit of the inverter is powered (24 V on terminal X11). The
power may only be switched off during the download when the software dis-
plays an appropriate instruction.
• You have connected the inverter to the PC via serial interface X3.
• POSITool is not communicating with the inverter via serial interface X3.
You will need:
• The program Download.exe which is stored in the Download folder in the di-
rectory of POSITool.
• The mot files which are stored in the same directory.
Proceed as shown below:
