4.3 Wiring
The precautions for wiring the Simple Motion module are given below. Refer to this
section as well as Section 4.1.3 "Handling precautions" when carrying out the work.
4.3.1 Precautions for wiring
DANGER
Completely turn off the externally supplied power used in the system before installation or
wiring. Not doing so could result in electric shock or damage to the product.
CAUTION
Check the layout of the terminals and then properly route the wires to the module.
The external input wiring connector must be crimped or pressured with the tool specified by the
manufacturer, or must be correctly soldered. Insufficient connections may cause short circuit,
fire, or malfunction.
Be careful not to let foreign matter such as sawdust or wire chips get inside the module. These
may cause fires, failure or malfunction.
The top surface of the module is covered with protective films to prevent foreign objects such as
cable off cuts from entering the module when wiring. Do not remove this film until the wiring is
complete. Before operating the system, be sure to remove the film to provide adequate
ventilation.
Securely connect the connector for SSCNET cable to the bottom connector on the module.
When removing the cable from the module, do not pull the cable. Hold the connector that is
connected to the module. Pulling the cable that is still connected to the module may cause
malfunction or damage to the module or cable.
The external input/output signal cable and the communication cable should not be routed near
or bundled with the main circuit cable, power cable and/or other such load - carrying cables
other than those for the PLC. These cables should be separated by at least 100mm (3.94inch)
or more. They can cause electrical interference, surges and inductance that can lead to mis-
operation.
The shielded cable for connecting Simple Motion module can be secured in place. If the
shielded cable is not secured, unevenness or movement of the shielded cable or careless
pulling on it could result in damage to the Simple Motion module, servo amplifier or shielded
cable or defective cable connections could cause mis-operation of the unit.
If the cable connected to the Simple Motion module and the power line must be adjacently laid
(less than 100mm (3.94inch)), use a shielded cable. Ground the shield of the cable securely to
the control panel on the Simple Motion module side. (A wiring example is given on this section
"[1] Precautions for wiring").
