Communication Setup: Inverter Setting (FC300, VLT2800)
Inverter Setting (FC300) | For normal communication, the following parameters must be set for the inverter. · Parameter 8-10 : FC profile [0] · Parameter 8-30 : FC MC [1]  [1] Those parameters must be matched with the settings of the Xpanel. [2] The parameters of 8-10 and 8-30 must be set as the value shown above. If those parameters are set as other values, Xpanel cannot communicate with the inverter. |
Inverter Setting (VLT2800) | For normal communication, the following parameters must be set for the inverter. · Parameter 512 : FC profile [1]  [1] Those parameters (500 and 501) must be matched with the settings of the Xpanel. [2] The parameter of 512 must be set as the value shown above. If this parameter is set as another value, Xpanel cannot communicate with the inverter. |
Communication Setup: Xpanel
Create a new device | For creating a new device go to [Tools] - [I/O Devices] or click The following picture demonstrates the first step for creating a new device.  I/O Device Name : Give a device name. This name will be used in the Tag configuration window of the database accompanied by the Station Name. |
Select a device type | After selecting [OK] on previous step, the ‘Serial Communication Configuration’ dialog box will be popped up as shown in following picture.  In this window, select the ‘Device Type’ as ‘DANFOSS VLT AutomationDrive FC-300’ and configure the proper serial communication parameters.
|
Create a station | Move to the ‘Station’ tab of ‘Serial Communication Configuration’ dialog box.  In this dialog box, all the connected PLC stations can be configured and registered to the Xpanel. Each field can be configured as followed: Station Name: Give a name to the PLC. This name will be used in the database window accompanied with the ‘Device Name’. Station Type: Choose the ‘FC-300’ (no other type can be selected). Network ID: This field has no effect. Station No.: Specify a number between 0 and 9. 16Bits Data Swap: This field has no effect. 32Bits Data Swap: This field has no effect. String Data Swap: This field has no effect. Using Checksum: This field has no effect. Comm. Error Message Pop Up: If this item is checked, Xpanel displays a communication error message at every Rx and Tx error. Otherwise, Xpanel does not display an error message. However, if there is an error when writing a tag value to the station value, the notification message will pop up. This message box automatically closes after 5 seconds. |
Address Notation
The address of a Tag in Xpanel has the following format.
...
The addresses above can be used in both analog and digital tags.
For more information on each point, please refer to the ‘FC 300 Design Guide’.

Example: Monitors the frequency data
Make an analog tag for frequency data. The address can be induced from parameter 16-13. Designate ‘P1613’ as the address of the new analog tag.
Setup the scale factor of the analog tag if needed. ‘Conversion index’ of parameter 16-13 is -1. Configure the scaling factor of the tag in the database as 0.1.
The ‘Conversion index’ and other useful information of each parameter can be found on the ‘Parameter Lists’ section of the ‘FC 300 Design Guide’.
...
Example: Changes the ‘speed PID lowpass filter time’
Make two analog tags. One tag is for EEPROM storage control and the other tag is for the parameter. The address of the parameter tag can be induced from parameter 07-06. Designate ‘P0706’ as the address of the new analog tag.
...
2. Setup the scale factor of the analog tag. In this example, the value of 0.1 was designated as the scale factor. The ‘Conversion index' of the parameter 07-06 is -4. This index is based on the unit of seconds. For convenience, we can use the unit of milli-seconds, such that the index can be thought of as the value of -1.
...
3. The parameter of FC 300 can be modified by changing the tag. If needed, the EEPROM storing option can be arranged before writing a new parameter value.
The following image shows an example of how to change a parameter:
...
Example: Start Controls
Make two analog tags for control. One tag is for a reference value (C001, INT16) and the other tag is for a control word (C000, UINT16).
...
2. To control the FC 300, write the desired reference value to the ‘Reference’ point, C001, first. Then, write a control value to the ‘Control' point. For example. write the value of 0x047F for issuing a start command.
The following picture shows an example of a command expression for control, starting with 100%.

Communication Cable Wiring
...
Shielded twisted pair cable must be used for P-N pair.
Ensure that the shield cable is connected to the COM terminal (61) of FC 300.
