Additional requirements for the servo drives concerning the UL approval Page 41
7 EMC-compliant cabling
The following must be considered for an EMC-compliant setup of the drive system:
Suitable installation and suitable wiring of all connection cables provided, the servo drives
ARS 2100 SE fulfill the requirements of the corresponding product standard EN 61800-3. This
standard refers to “classes” and so-called “environments”. The first environment includes mains
supplies serving residential buildings and the second environment includes mains supplies
exclusively serving industrial buildings.
The servo drive ARS 2100 SE 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 for usage in the first environment.
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.
In order to keep the leakage currents and the losses in the motor connection cable as small as
possible, the servo drive ARS 2100 SE should be located as close to the motor as possible (see also
the following chapter Operation with long motor cables, page 42).
Motor cable and angle encoder cable must be shielded.
The shield of the motor cable must be connected to the housing of the servo drive ARS 2100 SE
(shield connection terminal). The cable shield also has to be connected to the associated servo drive
so that the leakage currents can flow back into the servo drive causing the leakage. 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 must be connected to the PE connection point of the supply
connection [X9].
The inner PE conductor of the motor cable must be connected to the PE connection point of the
motor connection [X6].
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 (that is at a 90° angle), if
possible.
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 servo drive plane to the PE terminal; maximum length 40 mm.
Connect the total shield on the motor side plane to the connector housing or motor housing;
maximum length 40 mm.
