Rexroth IndraDrive Fc Drive Controllers Frequency Converters FCS01
● Select the lowest possible switching frequency. This reduces the intensi‐
ty of the electromagnet interference generated by the converter.
It is imperative that the safety regulations are observed when in‐
stalling the frequency converters!
Control lines, mains lines and motor lines must be run separately.
They must never be laid in one common cable pipe/duct. The test
equipment for high voltage insulation must not be used for cables
connected to the frequency converter.
Where no EMC measures have been taken, high-frequency interferences pri‐
marily caused by switching operations or lightning frequently result in faults in
electronic components of the bus nodes; therefore, trouble-free operation is
no longer guaranteed.
Professionally shielded bus cables dampen the potential electrical interferen‐
ces of an industrial environment. Take the following measures to realize opti‐
mum shielding properties:
● Keep the connections between bus nodes as short as possible.
● The shielding of the bus cable must be placed on both sides over a
large surface area.
● Avoid connecting field devices to the bus via branch circuits.
● Avoid extending bus cables via connectors.
In the case of different potentials to ground, a compensating cur‐
rent may flow through the shield connected on both sides which is
a potential risk to the electronic components. Equipotential differ‐
ences must be reduced by sufficient equipotential bonding.
The limit value classes listed below can be achieved when the following con‐
ditions are met:
