Important points to remember about I/O wiring:
• Use copper wire only. 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).
Important: I/O terminals labeled “(–)” Digital In Common or
“Common” are not connected to earth ground and are
designed to greatly reduce common mode interference.
Grounding these terminals can cause signal noise.
Step 4 I/O Wiring
!
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.
