EN 61800-5-1:2007, Section 4.3.5.5.2). If the cross section of the outer con‐
ductor is bigger, the cross section of the equipment grounding conductor
must also be bigger.
Design and installation in area B - control cabinet area prone to inter‐
ference
Arranging components and lines
Modules, components and lines in area B should be placed at a distance of
at least d1 = 200 mm from modules and lines in area A.
Alternative: Shield modules, components and lines in area B using distance
plates mounted vertically on the mounting plate from modules and lines in
area A or use shielded lines.
Only connect power supply units for auxiliary or control voltage connections
in the drive system to the mains with a mains filter. See
Install the shortest possible lines between drive controller and filter.
Control voltage or auxiliary voltage
connection
Only in exceptional cases should you connect power supply unit and fusing
for the control voltage connection to phase and neutral conductor. In this
case, mount and install these components in area A far away from the areas
B and C of the drive system. For details, see section
in area A - control cabinet area free from interference, page 175
.
Run the connection between the control voltage connection of the drive sys‐
tem and the power supply unit used through area B over the shortest dis‐
tance.
Line routing
Run the lines along grounded metal surfaces in order to minimize radiation of
interference fields to area A (transmitting antenna effect).
Design and installation in area C - control cabinet area highly prone to
interference
Area C mainly concerns the motor power cables, especially at the connection
point at the drive controller.
Influence of the motor power cable
The longer the motor power cable, the greater its leakage capacitance. To
comply with a certain EMC limit value, the allowed leakage capacitance of
the mains filter is limited. For the calculation of the leakage capacitance, see
the documentation on the drive system of the drive controller used.
●
Run the shortest possible motor power cables.
●
Only use shielded motor power cables from Rexroth.
Routing motor power and motor
encoder cables
Route the motor power and motor encoder cables along grounded metal sur‐
faces both inside and outside the control cabinet in order to minimize radia‐
tion from interference fields. If possible, route the motor power and motor en‐
coder cables in metal-grounded cable ducts.
Route the motor power and motor encoder cables:
●
With a distance of at least d5 = 100 mm from interference-free lines, as
well as to signal cables and signal lines
(alternatively separated by a grounded distance plate)
●
In separate cable ducts, if possible
Routing motor power cables and
mains connection lines
For converters (drive controllers with individual mains connection), route mo‐
tor power cables and (unfiltered) mains connection lines parallel to one an‐
other for a maximum distance of 300 mm. After that distance, route motor
power cables and power supply cables in opposite directions and preferably
in separate cable ducts.
