= Twisted Pair

Single Point PE Ground

Note: If the external controller does not have an internal terminating resistor R1, and R2 must be mounted within 3 ft [1 m] of the drive. A 120 ohm resistor is recommended for high frequency

(over 250 kHz) feedback signals or cable lengths longer than 25 feet.
