potential. When there are long distances between
the stations in a eldbus 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.
3.4 Cable Routing
NOTICE
EMC INTERFERENCE
Use screened cables for motor and control wiring, and
separate cables for eldbus communication, motor
wiring, and brake resistor. Failure to isolate eldbus
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 eldbus cable crosses a motor cable or a brake
resistor cable, ensure that the cables cross at an angle of
90°.

4.2.2 No Communication with the
Frequency Converter
When there is no communication with the frequency
converter, proceed with the following checks:
1. Check that 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 nal 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.
