30 PowerFlex® 700S Drives - Phase I Control (Frame Sizes 9 & 10)
Step 8: Control Wiring
Wiring Recommendations
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.

!
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.
