3.3 EMC-compliant Installation
To obtain an EMC-compliant installation, follow the instructions provided in the relevant frequency converter Operating Instructions and Design Guide. Refer to the fieldbus master manual from the PLC supplier for further installation guidelines.
3.4 Grounding
- Ensure that all stations connected to the fieldbus network are connected to the same ground potential. When there are long distances between the stations in a fieldbus network, connect the individual station to the same ground potential. Install equalising cables between the system components.
- Establish a grounding connection with low HF impedance, for example by mounting the frequency converter on a conductive back plate.
- Keep the ground wire connections as short as possible.
3.5 Cable Routing
NOTICE
EMC INTERFERENCE
Use screened cables for motor and control wiring, and separate cables for fieldbus communication, motor wiring, and brake resistor. Failure to isolate fieldbus communication, motor, and brake resistor cables can result in unintended behaviour or reduced performance. Minimum 200 mm (7.9 in) clearance between power, motor, and control cables is required. For power sizes above 315 kW, it is recommended to increase the minimum distance of 500 mm (20 in).
NOTICE
When the fieldbus cable crosses a motor cable or a brake resistor cable, ensure that the cables cross at an angle of 90°.

3.6 Topology
The PROFINET module features a built-in Ethernet switch with 2 Ethernet RJ 45/M12 connectors. The module enables the connection of several PROFINET options in a line topology as an alternative to a traditional star topology. The 2 ports are equal. Select and use the 2 ports freely.
Line Topology
In many installations, line topology enables simpler cabling and the use of smaller Ethernet switches. The PROFINET interface supports line topology with its 2 ports and builtin Ethernet switch. When line topology is used, take precautions to avoid timeout in the PLC when more than 8 frequency converters are installed in series. Each frequency converter in the network adds a small delay to the communication due to the built-in Ethernet switch. When the update time is too short, the delay can lead to timeout in the PLC. Set the update time as shown in Table 3.1. The numbers given are typical values and can vary from installation to installation.
| Numbers of frequency converters connected in series | Minimum update time [ms] |
| <8 | 2 |
| 8-16 | 4 |
| 17-32 | 8 |
| 33-50 | 16 |
| >50 | not recommended |
Table 3.1 Minimum Update Time
NOTICE
In a line topology, activate the built-in switch by powering all frequency converters, either by mains or a 24 V DC option card.
NOTICE
Installing frequency converters of different power sizes in a line topology may result in unwanted power-off behaviour while using controlword timeout (8-02 Control Word Source to 8-06 Reset Control Word Timeout). It is recommended to mount the frequency converters with the longest discharge time first in the line topology. In normal operation, the larger power size frequency converters have a longer discharge time.
Ring topology can increase the availability of an Ethernet network.
For ring topology:
- Install a special switch (redundancy manager) between the PLC and the frequency converters.
- Configure the redundancy manager switch to clearly define the ports that connect to the ring.
The redundancy manger sends out test frames on its 2 ports where the ring is connected. When no test frames are lost, the redundancy manager keeps the ring in operational. If the switch detects a fault in the ring, it reconfigures the ring into 2 lines instead. The transition time from 1 ring into 2 lines is up to 500 ms, depending on the components installed in the ring. Set the timing of the PLC to ensure that the transition time does not lead to timeout fault.
NOTICE
For ring/redundant line topology, ensure that the redundancy manager switch supports detection of loss of line topology. The switch inside the PROFINET interface does not support this detection.
Recommended design rules
- Pay special attention to active network components when designing an Ethernet network.
- For line topology, a small delay is added with each additional switch in the line. See Table 3.1 for more information.
- Do not connect more than 50 frequency converters in series. Exceeding this limit can result in unstable or faulty communication.
3.7 Setting Address Switches
The option has address switches that are used to set the station name (host name). This feature is available from firmware version 3.00 onwards.
- When all switches are set to On, or all are set to OFF, change the station name via 12-08 Host Name or via DCP command.
- In all other combinations, the address switches have priority over the parameter setting. The station name is set based on the value in 15-40 FC Type, and a 3-digit number selected from the DIP settings.
Use the address switches to set the 253 different station names according to Table 3.2:
| Switch | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |
| 12-08 Host Name | +128 | +64 | +32 | +16 | +8 | +4 | +2 | +1 |
| FC-302-005 | OFF | OFF | OFF | OFF | OFF | ON | OFF | ON |
| FC-302-035 | OFF | OFF | ON | OFF | OFF | OFF | ON | ON |
| FC-302-082 | OFF | ON | OFF | ON | OFF | OFF | ON | OFF |
| FC-302-212 | ON | ON | OFF | ON | OFF | ON | OFF | OFF |
Table 3.2 Host Names Setting (FC 302 used in this example)
The station name change comes into effect at the next power-up. Read the station name in 12-08 Host Name.
