*1. 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.
*2. This depends on the Unit configuration.
