Figure 3.23 Preparing the Ends of Shielded Cables
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.
