Besides reading this manual and the controller user's manual, also be sure to handle the equipment
correctly while paying sufficient attention to safety.
Points regarding safety in this manual only list items involving this product. Please refer to the controller

CAUTION
Ethernet communications protocol specifications do not guarantee real-time operation. So relying only on the
Ethernet in situations such as robot emergency stop can be extremely dangerous. Install safety interlock circuits
using the emergency stop terminal in the SAFETY connector of the robot controller to ensure quick and
effective emergency stops.
c
CAUTION
To find the current status of the network system and robot controller when communication errors occur on the
Ethernet system, refer beforehand to this manual and the instruction manual for equipment used by the other
party. Also install safety interlock circuit so that systems including a robot controller will function reliably and
safely when communication errors occur.
c
CAUTION
Do not bundle control lines or communication cables together or in close contact with main circuit or motor/
actuator lines. As a general rule, maintain a gap of at least 100mm. Noise in signal lines may cause faulty
operation.
