I/O Wiring
Important points to remember about I/O wiring:
• Always use tinned copper wire.
• Wire with an insulation rating of 600V or greater is recommended.
• Control and signal wires should be separated from power wires by at
least 0.3 meters (1 foot).
• 4100CCF3 Flex I/O cable for use with DriveLogix is 3 ft. maximum
length
.
Important: I/O terminals labeled “(–)” or “Common” are not referenced to
earth ground and are designed to greatly reduce common mode
interference. Grounding these terminals can cause signal noise.
Table 1.G Recommended Control Wire
!
ATTENTION: Hazard of personal injury or equipment damage
exists when using bipolar input sources. Noise and drift in sensitive
input circuits can cause unpredictable changes in motor speed and
direction. Use speed command parameters to help reduce input
source sensitivity.

If the wires are short and contained within a cabinet which has no sensitive circuits, the use of shielded wire
may not be necessary, but is always recommended.
