*1 One End Cover NX-END01 is provided with the NX-series Communications Coupler Units.
*2 This depends on the specifications of the EtherCAT master. For example, the values are as follows when the EtherCAT
    Coupler Unit is connected to the built-in EtherCAT port on an NJ5-series CPU Unit: 500 μs, 1,000 μs, 2,000 μs, and
    4,000 μs. Refer to the NJ/NX-series CPU Unit Built-in EtherCAT Port User's Manual (Cat. No. W505) for the specifications
    of the built-in EtherCAT ports on NJ/NX-series CPU Units.
    This also depends on the unit configuration.
