Lengthening I/O Cables
Bear in mind that lengthening cables increases noise sensitivity. (The maximum length of
cables is ultimately determined by the environment in which the equipment will be used.)
If you lengthen the cables, follow the precautions below to minimize noise problems.
• Use a minimum wire size of 22 AWG.
• Use twisted pair shielded cables and connect the shield to a
SHLD
terminal on the
ZETA6xxx. Leave the other end of the shield disconnected.
• Do not route I/O signals in the same conduit or wiring trays as high-voltage AC wiring or
motor cables.
Reducing noise on limit, trigger, and P-CUT inputs. If you are experiencing noise
problems, try adding resistors to reduce noise sensitivity (see illustration below).
