3.7 Control Circuit Wiring
YASKAWA ELECTRIC SIEP C710606 44B YASKAWA AC Drive T1000V Technical Manual 61
To disconnect control wires from the terminals use the procedure described in the following figure. Grasp the wire where
it enters the terminal with a pair of pliers, then use a slotted-tip screwdriver to release the terminal and pull the wire out.
If it fits tightly, i.e., if ferrules are used, turn the wire 45 degrees and gently remove it. Use this procedure to remove the
wire jumper between terminals HC and H1 that is installed at shipping.

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.
