Installation

Safety Instructions
See chapter 2 Safety for general safety instructions.

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.

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.
• Establish electrical contact between the cable screen and the frequency converter enclosure by using metal cable glands or by using the clamps provided on the equipment.
• Use high-strand wire to reduce electrical interference.

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 from 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 to 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°.

Mounting

1. Check whether the fieldbus option is already mounted in the frequency converter. If already mounted, go to step 6. If not mounted, go to step 2.
2. Remove the LCP or blind cover from the frequency converter.
3. Use a screwdriver to remove the front cover and the LCP cradle.
4. Mount the fieldbus option. Mount the option with the connector facing up for top cable entry (see Illustration 3.3), or with the connector facing down for bottom cable entry (see Illustration 3.4). If an MCB option is installed, only top cable entry is possible.

Table 4.2 LED: Network Status (NS)

No Communication with the Frequency Converter
When there is no communication with the frequency converter, proceed with the following checks:

1. Check that the cabling is correct. Check that the cables are connected to the correct terminals as shown in Illustration 3.6.
2. Check that the bus connection is terminated at both ends. If not, terminate the bus connection with termination resistors at the initial and final nodes.
3. Check that each node connected to the CANopen network has a unique node ID (address). If 2 devices have the same node ID, it leads to malfunction in the network.
4. Communication drops out after some time. Check the installation for correct routing of the CANopen cables. Check if the screen of the motor cable is mounted correctly.
5. Communication is unstable. Check parameter 10-05 Readout Transmit Error Counter and parameter 10-06 Readout Receive Error Counter. These 2 parameters have to be close to 0 most of the time. If they show higher values, check the CANopen cable for interference, wrong termination, and so on.
