3.2 Notices in Wiring
3.2.1 Notices in Wiring
(1) The length of connecting cable between positioning module and drive machine shall be as short as possible.
(Max. length : 10m).
(2) For cross current and external I/O signal of positioning module, it is required to use the separate cables to avoid
the surge or induction noise generated from the cross current.
(3) The wires should be selected considering surrounding temperature, allowable current and it is recommended to
be more than max. size AWG22(0.3㎟).
(4) In wiring, if it is too close to the high temperature machine or material or it is directly contacted to the oil for a
long time, the short-circuit will occur that may cause the damage or malfunction.
(5) Make sure to check the polarity before applying the external contact signal to the terminal board.
(6) In case of wiring the high voltage cable and power cables together, the induction obstacle occurs that may
cause the malfunction or failure.
(7) In case of wiring by the pipe, the grounding of pipe is required.
(8) In case that there is considered to be the noise source in wiring between positioning module and drive machine,
it is required to use and connect Twist pair and sealed cable for the wiring of output pulse that comes from the
positioning and enters into the motor drive.
