700H Control Wiring
Important points to remember about I/O wiring:
• Always use 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).
Important:Control (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.
Signal and Control Wire Types

!
ATTENTION: Inputs must be configured with software and
jumpers (see page 2-6
). In addition, configuring an analog input
for 0-20mA 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.
