Under no circumstances can contacts that control the movement of
inductive loads, inductances without interference protection, or
connections between such elements, be used in the same area as the
control.
This means that the control must be separated from such sources of
interference by a Faraday’s cage (its own section in the control cabinet).
The controller cables must meet the minimum requirements for diameter,
shielding and grounding listed in the Terminal Connection Diagrams. The
illustrated branching conditions must also be met. It does not suffice to
establish the galvanic connections; the connection points must be
adhered to.
If, for example, two parallel leads that branch from one point are shown, it
is unacceptable to connect only one lead and to branch it at a later point.
Induction looping (error transmitters and antennas) and potential shifting
that causes interference can occur.
The switching signal inputs and outputs are galvanically isolated using an
opto-electronic coupler and can be wired without much concern.
However, these cables are subject to interference and must therefore be
kept well away from all other controller cables for every part of the
installation.
This means that these cables must be wired to the controller from a
different direction or, when wired in parallel, they must be run through
separate steel tubing.
Of course, the same is true for the cables for the respective power supply.
The cables between the controller and the drive electronics should be as
short as possible.
With the exception of the switching signal inputs and outputs described
above, the controller cables are subject to the following rules.
No unshielded wiring in areas without interference protection (cabinet and
canal). See also Section 13.1, ’Interference Suppression.’
No parallel wiring of controller, network and power cables without special
protection measures for the controller cables.
No parallel wiring of controller cables with other system cables without
special protection measures for the controller cables.
This means: Controller cables and controller power cables, when wired
parallel to other system components, must be run through steel or other
metal tubing. This is also valid, even if these cables are already shielded
and also in relation to the power cables for the electric servo drives.
