When setting the frequency by analog reference from an external potentiometer, use shielded
twisted-pair wires and ground the shield of twisted-pair wires to the ground terminal of the
drive.
NOTICE: The analog signal lines between the drive and the operator station or peripheral equipment should
not exceed 50 meters when using an analog signal from a remote source to supply the frequency reference.
Failure to comply could result in poor system performance.
