Important points to remember about I/O wiring:

• Use Copper wire only. Wire gauge requirements and recommendations

are based on 75 °C (167 °F). 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 “(–)” or “Common” are not referenced to

earth ground and are designed to greatly reduce common mode
interference. Grounding these terminals can cause signal noise.

Step 5

I/O Wiring

ATTENTION: Configuring an analog input for 0…20 mA
operation and driving it from a voltage source could cause
component damage. Verify proper configuration prior to
applying input signals.

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.
