[Wiring example of shielded cable]

Connector
(A6CON1)
To the Simple Motion module

[1] Precautions for wiring

(1) Use separate cables for connecting to the Simple Motion module and for the
power cable that create surge and inductance.
(2) The cable for connecting the Simple Motion module can be placed in the
duct or secured in place by clamps. If the cable is not placed in the duct or
secured by clamps, unevenness or movement of the cable or careless
pulling on it could result in damage to the unit or cable or defective cable
connections could cause mis-operation of the unit.
(3) If a duct is being used, separate the cables to connect the Simple Motion
module from the power line duct, or use metal piping.
Ground the pipes securely after metal piping.
(4) Use the twisted pair shielded cable (wire size 0.3 mm
shielded must be grounded on the Simple Motion module side.
(5) Use separate shielded cables of the forced stop input signal (EMI,
EMI.COM), limit signal (FLS, RLS, DOG, STOP), external command
signal/switching signal (DI, COM), and manual pulse generator/incremental
synchronous encoder input signal (HAH, HAL, HBH, HBL, HA, HB, 5V, SG)
for connecting to the Simple Motion module. They can cause electrical
interference, surges and inductance that can lead to mis-operation.
The following shows a wiring example for noise reduction in the case when the
connector (A6CON1) is used.
The length between the connector and the
shielded cables should be the shortest possible.
