Requirements for the connection
Connecting to a Danfoss Editron inverter, LCL filter, supercapacitor or other device requires a USB-to-serial service cable and PowerUSER computer program. PowerUSER is a free software provided by Danfoss Editron, and it can be downloaded from the Editron website.
Note: If you cannot connect to an inverter with PowerUSER, make sure that you have downloaded and installed the latest version of PowerUSER from the Danfoss Editron website.
Service cables can be ordered from Danfoss Editron, please use the spare parts order form. The cables can be ordered either 3 or 10 meters long.
How to connect
Start forming the connection by making sure that the device is powered up with a 24 V power supply, and the service cable is firmly attached to the device. A high-voltage connection is not required. The location of the serial ports of the EC-C1200 inverter and EC-MG1200 multiconverter are highlighted in the pictures below.
After connecting the serial cable, serial connection and the correct USB port should be chosen from the Settings tab in PowerUSER. With the Danfoss PSSC cable, there are two COM ports available per one cable, and the (numerically) first one is always used for PowerUSER connection. For example, if PowerUSER lets you choose between COM5 and COM6 ports, COM5 will be the correct one. A flashing green light at the bottom right corner indicates that a connection has been formed and is active. You should also see the description of the connected device on the left side of the bottom information bar.
If the connection is not working - troubleshooting
- Reboot the computer and inverter and try again.
- Check that the USB-serial adapter is detected correctly by the computer: open device manager in windows and expand the category "Ports (COM & LPT)". If there are no USB COM ports listed, reinstall the FTDI USB-serial drivers. A working USB-serial adapter will be shown in the list as two "USB Serial Port (COMx)" items, as shown in the picture below.
- Make sure that the inverter is powered with the 24 V aux power. If possible, check that the inverter is sending messages to the CAN bus, outputting a resolver signal, or the 5 V external sensor output to confirm the inverter is actually powering up and there is nothing wrong in the power supply or connections. Check that the power supply can provide enough power and current to the inverter.
- Check that you have selected the correct COM port from PowerUSER settings tab. If unsure, try all the available COM ports, wait at least 20 seconds after selecting a port to establish connection.
- Check that the M12 connectors on the inverter and the serial cable are clean, dry and undamaged. If using an old/worn serial cable, try with another cable to make sure that the serial cable is not broken.
