• This object gives the specifications of the EtherCAT communications mode for Sync Manager 3.
• Subindex 01 hex gives the EtherCAT communications mode that you can select for Sync Manager 3
of the EtherCAT Coupler Unit.
0000 hex: Free-Run Mode
0002 hex: DC Mode (Sync0)
This mode is synchronized with the Sync0 event.
• Subindex 02 hex gives the cycle time.
In Free-Run Mode, the time between two local timer events is given.
In DC Mode (Sync0), the synchronization cycle of Sync0 is given.
• Subindex 03 hex gives the shift time of the EtherCAT Slave Terminal. By setting the shift time, the
time from Sync0 until the NX Unit input synchronization timing can be increased. When you do not
set the shift time, it is the same as the result of the following calculation.
Minimum cycle time
−
Total of the Calc and Copy Time for Sync Managers 2 and 3
The shift time is valid only in DC Mode when the Unit configuration information is registered. When
moving from Init state to Pre-Operational (Pre-Op) state, the shift time is initialized.
• Subindex 04 hex gives the type of synchronization that is supported by the EtherCAT Coupler Unit.
Free-Run Mode and DC Mode (Sync0) are supported.
• Subindex 05 hex gives the minimum cycle time that is supported by the EtherCAT Slave Terminal.
• Subindex 06 gives the amount of time it will take for the EtherCAT Slave Terminal to process the pro-
cess data.
• Subindex 0B hex gives the value of the error counter in the EtherCAT Slave Terminal. This counter is
incremented if processing in the EtherCAT Slave Terminal is not completed within the synchroniza-
tion cycle.
