[2023-12-19] The latest version of PowerUSER is required to connect to new inverters. For more information see the below link:https://danfosseditron.zendesk.com/hc/en-gb/articles/5045659438877-EC-C1200-hardware-modifications-and-required-actions-due-to-it- |
Note that it is is recommended to connect to Editron devices initially using the service connection with a standard Danfoss service cable, see the article PowerUSER connection (USB-serial cable) for more information. For CAN bus wiring instructions, follow the CAN bus wiring guide.
Connecting to an EC-C1200 inverter with PowerUSER via CAN bus requires a PEAK PCAN adapter. All PEAK adapters which utilize the PCANBasic API can be used with PowerUSER, for example the PCAN-USB FD (figure 1).
Figure 1. Peak PCAN-USB FD adapter.
To install all necessary drivers and establish the connection correctly, perform the following procedure:
1) Connect the PEAK adapter to your computer and allow windows to install the necessary drivers.
2) Shut down PowerUSER and other programs that are using the CAN bus or CAN adapter.
3) Download the PCAN basic API from the PEAK website*. Copy and paste the PCANBasic.dll -file to your PowerUSER installation folder, and windows system folders according to the following:
On Windows 32-bit systems:
32-bit DLL -> Windows\System32
On Windows 64-bit systems:
32-bit DLL -> Windows\SysWOW64
64-bit DLL -> Windows\System32
Refer to the instructions included in the PCAN basic API for additional help regarding the .dll -files.
4) Open PowerUSER, and connect to the inverter via a regular USB-serial cable. Check which CAN bus has been selected for the inverter diagnostic CAN connection, from the following parameter:
[Firmware v. 11] Communications -> PowerUSER connection -> CAN port (10.6.1)
[Firmware v. 7] pdp -> can_channel (3000.1)
The default setting is CAN A. If necessary, change it to CAN B.
5) Check the inverter CAN address (node ID) for the selected CAN bus from the following parameter:
[Firmware v. 11] Communications -> Port settings -> CAN A / CAN B -> Address (10.1.1.2 / 10.1.2.2)
[Firmware v. 7:] system -> can_node_base_address_A / can_node_base_address_B (1001.7 / 1001.8)
6) Switch to the connection tab in PowerUSER, as shown below. Change the connection selection to CAN, and select the correct baudrate for the CAN bus (by default 250 kbaud/s). Change the remote ID to the inverter's CAN address. Local ID determines the CAN ID of the PowerUSER/PC, and it can be left to the default value unless it is already occupied by some other device on the CAN bus.
7) Wait approx. 30 seconds to establish the connection. A green light in the bottom right corner will blink when the connection is working, and the inverter type and name will appear in the left hand side of the bottom bar. All features of PowerUSER can now be accessed via the CAN bus, and the USB-serial cable can be disconnected, if necessary.
If the connection is not working:
- First, try rebooting both the computer and the inverter.
- Go to the Danfoss website and make sure that you have the latest version of PowerUSER installed.
- Check that the installation procedure above was followed and make sure the PCANbasic.dll is installed correctly.
- Test the PEAK adapter with PCANView software and make sure that the adapter is working correctly.
- Make sure that the CAN bus load is below 40%. The PowerUSER connection via CAN bus can generate over 30 % additional load to the bus, and is very sensitive to a high bus load.
- You can use the PCANView to check that PowerUSER is successfully initiating the connection: first, start PowerUSER and select CAN bus connection, then start PCANView and check that there are additional messages with the PGN 0x1BDA0DNN on the CAN bus, where NN is either the CAN address of PowerUSER or the inverter. If there are no such messages visible, there is likely something wrong with the PEAK CAN adapter configuration.
