[Wiring Precautions]
CAUTION
● Ground the controllers, servo amplifiers and servo motors embedded with a Simple Motion board with
a ground resistance of 100 ohm or less. Do not use a common grounding with other equipment.
● Check the rated voltage and signal layout before wiring to the Simple Motion board, and connect the
cables correctly. Connecting a power supply with a different voltage rating or incorrect wiring may
cause fire or failure.
● Connectors must be correctly connected. Incomplete connections may cause short circuit, fire, or
malfunction.
● Securely connect the connector to the Simple Motion board. Poor contact may cause malfunction.
● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100 mm or more between them. Failure to do so may result in malfunction
due to noise.
● Place the cables in a duct or clamp them. If not, dangling cable may swing or inadvertently be pulled,
resulting in damage to the Simple Motion board or cables or malfunction due to poor contact. Do not
clamp the extension cables with the jacket stripped. Doing so may change the characteristics of the
cables, resulting in malfunction.
● Check the interface type and correctly connect the cable. Incorrect wiring (connecting the cable to an
incorrect interface) may cause failure of the Simple Motion board and external device.
● When disconnecting the cable from the Simple Motion board, do not pull the cable by the cable part.
For the cable with connector, hold the connector part of the cable. Pulling the cable connected to the
Simple Motion board may result in malfunction or damage to the Simple Motion board or cable.
● Prevent foreign matter such as dust or wire chips from entering the personal computer. Such foreign
matter can cause a fire, failure, or malfunction.
● For Ethernet cables to be used in the system, select the ones that meet the specifications in the user's
manual of the Simple Motion board. If not, normal data transmission is not guaranteed.
[Startup and Maintenance Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before cleaning or retightening the
board-fixing screws. Failure to do so may result in electric shock or malfunction.
● Turn off the external power supply for the system in all phases before installing the Simple Motion
board to or removing it from the personal computer. Failure to do so may result in electric shock or
cause the Simple Motion board to fail or malfunction.
● Do not connect or disconnect any communication cable while power is on. Doing so may result in a
malfunction.
