7 EMC-compliant cabling
The following must be considered for an EMC-compliant setup of the drive system:
In the first environment, the servo positioning controller ARS 2300 FS must be installed in a steel
switch cabinet. In most cases a standard model will sufficiently attenuate emitted interference. The
cable shields must be connected with the switch cabinet housing by means of metal cable glands.
In the second environment the servo positioning controller ARS 2300 FS can also be used without
a steel control cabinet. Installation in a control cabinet (possibly plastic), however, is still
necessary to guarantee proper usage.
The control cabinet bed plate must be conducting (zinc-coated design). The imperative central
grounding point should also be located on the control cabinet bed plate.
The signal lines must be as far away from the power cables as possible. They should not be
placed parallel. If intersections cannot be avoided, they should be perpendicular (i.e. at a 90°
angle), if possible.
In order to keep the leakage currents and the losses in the motor connection cable as small as
possible, the servo positioning controller ARS 2300 FS should be located as close to the motor as
possible (see also the following chapter).
The shield of the motor cable is connected to the housing of the servo positioning controller
ARS 2300 FS (shield connection terminal). In the first environment the shield of the motor cable
also has to be connected to the control cabinet housing by means of metal cable glands.
The mains-end PE connection is connected to the PE connection point of the supply connection
[X9].
The inner PE conductor of the motor cable is connected to the PE connection point of the motor
connection [X6].
Motor cable and angle encoder cable must be shielded.
Unshielded signal and control lines should not be used. If their use is inevitable they should at
least be twisted.
Even shielded cables will inevitably have short unshielded ends (unless shielded connector
housings are used). In general, the following applies:
Connect the inner shields to the corresponding pins of the connectors; Maximum length
40 mm
Length of the unshielded cores 35 mm maximum
Connect the total shield on the controller side flat to the PE terminal; Maximum length 40 mm
Connect the total shield on the motor side flat to the connector housing or motor housing;
Maximum length 40 mm
Caution!
In residential surroundings this product may cause high frequency disturbances, which
may require interference rejection measures.
