Design and Installation in Strongly Interference-
Susceptible Area of Control Cabinet (Area C)
Area C mainly concerns the motor cables, especially at the connection
point at the device.
The discharge capacitance is limited to ensure compliance with the limit
values. The calculation of the discharge capacitance can be found in the
"Calculations" chapter.
If the applications allows this, the cable length should always be kept
short. Avoid unnecessary line lengths.
The motor cables have to be run in shielded form. Besides they are
always to be routed with a distance of d5 = 100 mm to the other
interference-free lines and to signal cables and lines, or to be separated
from them by a grounded distance plate. The latter is not required for the
feedback cables of Rexroth motors.
At the drive controller connection the motor cables and the (unfiltered)
power connection lines may only be routed in parallel for a distance of
300 mm. After that distance, motor cables and power supply cables have
to be routed in opposite directions in separate cables ducts, as illustrated
in the following figures (Fig. 6-32; Fig. 6-33) by the example of a drive
system with separate mains connection per drive axis IndraDrive HCS.
cable duct 1:
mains connection
lines
cable duct 2:
motor cable
drive controllers
parallel routing:
length max. 300 mm
with a distance of at least 100 mm
or separated by grounded
distance plate
Area B Area C
motor cable:
shield contact via clips at least at one point:
alternatively at device or on mounting plate at
control cabinet outlet
