Control Wiring for PowerFlex 700S Drives with
Phase II Control
I/O Wiring Important points to remember about I/O wiring:
• Always use tinned copper wire.
• Wire gauge requirements and recommendations are based on 75 °C. Do
not reduce wire gauge when using higher temperature 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
.
Table 14 - Recommended Control Wire
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.
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.

(1) Control and signal wires must be separated from power wires by at least 0.3 meters (1 foot).
(2) 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.
