▶ Use low-capacitance cables. If possible, design the cable connections without intermediate terminals.
▶ Electro-magnetic sources of interference (e.g. frequency converters) must not be arranged in the immediate
vicinity of the controller card.
▶ Power cables must not be laid in the immediate vicinity of the controller card.
▶ Lines of the controller card must not be laid in the immediate vicinity of power cables.
▶ Pass the sensor lines separately.
▶ The distance to aerial lines, radios, and radar systems has to be 1 meter at least.
▶ Design the installation so that when the diff erential inputs are used, both inputs are always connected or dis-
connected at the same time.
▶ For switching command values, relays with gold-plated contacts have to be used. (Low voltages, low currents)
▶ Always shield command value lines and actual value cables. Connect the shield to "Shield" on the card side and
leave the other side open as otherwise, there is the risk of ground loops.
▶ Use highly fl exible CU conductors (at least 2.5 mm
The system earth is a main part of the EMC protection of the controller card. Here, interference is eliminated
which is transported to the controller card via the data and supply voltage lines. This function is only ensured if
the system earth itself does not introduce interference into the controller card. Rexroth recommends screening
the solenoid conductors as well.
