Wiring
Use 12 AWG wire for the AC line voltage (L1 and L2), motor armature (A1 and A2),
and dynamic brake resistor (if used). Use 18 AWG wire for logic (field output, speed
adjust potentiometer, tachogenerator, etc.)
Twist logic wires to avoid picking up unwanted electrical noise. Use shielded cable if
wires are longer than 12 inches (30 cm).
Do not bundle logic wires with power carrying wires. This can cause erratic operation.
Keep logic wires in a conduit separated by at least 2 inches from power carrying
wires. Do not allow logic wires to travel in parallel to power carrying wires for more
than 1 inch.
It may be necessary to earth ground the shielded cable. If noise is produced by
devices other than the drive, ground the shield at the drive end. If noise is generated
by a device on the drive, ground the shield at the end away from the drive. Do not
ground both ends of the shield.
