conductor is bigger, the cross section of the equipment grounding conductor
must be accordingly bigger.
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 by 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 via a mains filter. See
Areas (Zones), page
Install the shortest possible lines between drive controller and filter.
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
lation in Area A - Interference-Free Area of Control Cabinet, page
Run the connection between control voltage connection of the drive system
and power supply unit used through area B over the shortest distance.
Run the lines along grounded metal surfaces, in order to minimize radiation
of interference fields to area A (transmitting antenna effect).
Area C mainly concerns the motor power cables, especially at the connection
point at the drive controller.
The longer the motor power cable, the greater its leakage capacitance. To
ble
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 by Rexroth.
Route the motor power cables and motor encoder cables along grounded
metal surfaces, both inside the control cabinet and outside of it, in order to
minimize radiation of interference fields. If possible, route the motor power
cables and motor encoder cables in metal-grounded cable ducts.
Route the motor power cables and motor encoder cables
●
with a distance of at least d5 = 100 mm to 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
For converters (drive controllers with individual mains connection), route mo‐
tor power cables and (unfiltered) mains connection lines in parallel for a maxi‐
mum distance of 300 mm. After that distance, route motor power cables and
power supply cables in opposite directions and preferably in separate cable
ducts.
