Noise Zones when Using Regenerative Power Supplies (with/without a Line Filter Unit)
Observe the following guidelines when laying out a Kinetix 7000 system panel if
a regenerative power supply (8720-RPS
xxxxx) is used (see
Figure 10 ), and if a
regenerative power supply and line filter unit are used (see Figure 11 on page 32 ).
• Mount the regenerative power supply to the right of the drive.
• The clean zone (C) is beneath and left of the Kinetix 7000 drive. This zone
includes the motor feedback, auxiliary feedback and registration signals
from the IOD connector (grey wireway).
• The dirty zone (D) is to the right of the Kinetix 7000 drive. This zone
includes the motor power, GPIO, GPR, SO, and IOD connections (black
wireway).
• The very dirty zone (VD) includes both the 8720MC-RPS DC output to
the Kinetix 7000 drive and the fuses, contactors, circuit breakers, and AC
line input to the EMC line filter to the right of the 8720MC-RPS.
Shielded cable is required only if the very dirty cables enter a wireway.
• The SERCOS fiber-optic cables are immune to electrical noise.
