Precautions for Correct Use
• The cable between any two nodes (L1, L2 ... Ln) must be 100 m or less.
• Firmly connect the communications cable connector until it clicks into place.
• When you install the communications cables, observe the cable specifications (e.g., bending
radius) of the cable manufacturer.
• Do not disconnect the communications cables from the EtherCAT Slave Units during opera-
tion. The outputs from the EtherCAT master may become unstable.
Additional Information
Make sure the cable between each pair of devices connects an output port to an input port.
Normal communications are not possible if an output port is connected to another output port or
an input port is connected to another input port.
