line interface module is used in the system and mounted right of the drive with
the AC (EMC) line filter mounted behind the line interface module:
•
The clean zone (C) is to the left and beneath the drive system (gray
wireway).
•
The dirty zone (D) is to the right and above the drive, and above and
below the line interface module (black wireway).
•
The very dirty zone (VD) is from the filter output to drive. Shielded cable
is required on the EMC filter (LOAD side) and the braided shield
attached to the clamp (when provided).
•
The sercos fiber-optic cables are immune to electrical noise.
Figure 4 - Establishing Noise Zones (EMC filter behind the line interface module)
(1) If the drive system I/O cable contains (dirty) relay wires, route cable with the module I/O cable in dirty wireway.
(2) When space does not permit the 150 mm (6.0 in.) segregation, use a grounded steel shield instead. For examples, see the System
Design for Control of Electrical Noise Reference Manual, publication
GMC-RM001
.
(3) The Kinetix 6000 drive is shown as an example of any drive or other device in configuration with the line interface module; however,
noise zones of other products will vary.
