Line Interface Module
Observe these guidelines when a 2094-AL09 or 2094-BL02 line interface
module is used in the drive system:
•
The clean zone (C) is to the right and beneath the drive system (gray
wireway).
•
The dirty zone (D) is to the left and above the drive, and above and below
the line interface module (black wireway).
•
The very dirty zone (VD) is limited to where the line interface module
VAC output jumpers over to the drive. Shielded cable is required only if
the very dirty cables enter a wireway.
•
The sercos fiber-optic cables are immune to electrical noise.
Figure 5 - Establishing Noise Zones (catalog numbers 2094-AL09 or 2094-BL02)
(1) If drive system I/O cable contains (dirty) relay wires, route cable with 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.
