EMC compliant cabling
The following must be considered for an EMC-compliant setup of the drive system (see also
chapter 6 Electrical installation
▪
In order to keep the leakage currents and the losses in the motor connection cable as
small as possible, the servo positioning controller should be located as close to the
motor as possible.
▪
Motor cable and angle encoder cable must be shielded.
▪
The shield of the motor cable is connected to the housing of the servo positioning
controller (shield connection terminal). The cable shield also has to be connected to
the associated servo positioning controller so that the leakage currents can flow back
into the controller causing the leakage.
▪
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].
▪
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 controller side 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.
DANGER!
For safety reasons, all PE ground conductors must be connected prior to initial
operation.
The EN 61800-5-1 regulations for protective earthing must be complied with
during installation!
