Although the robot controller unit complies with EMC standards and has a certain amount of resistance to
external noise, there may be cases in which communication is affected by noise depending on the environment
in which the equipment and cable are located.
If communication is affected by noise, a communication error occurs, possibly causing the robot to enter an
emergency stop state, or causing throughput to decline. If there is a source of noise, and this noise is suspected
of affecting communication, please take the following countermeasures.
1. Equipment and cable selection
As the equipment to be connected to the network, select units that conform to EMC directives. Be sure to use cable of
the prescribed specifications.
2. Equipment and cable placement and grounding
If the noise source is nearby, create an appropriate distance between the noise source and the network environment
including the cable. For the robot controller unit and equipment connected to it, be sure to attach an appropriate ground
as directed by the manual of each unit.
3. Adding anti-noise components
Apply the following measures to the robot controller.
• Install a ferrite core on both ends of the cable immediately adjacent to the connector of the device.
• Install a ferrite core or noise filter on the power supply input of the controller.
