6.4.1 DC configuration in the master
By default, the application of the DC synchronisation is deactivated in the device description ( 34) .
Parameterise the DC synchronisation in the EtherCAT configuration software (»PLC Designer«,
»TwinCAT«).
Set the synchronisation cycle time in the master. It is mainly defined by the processing time of the
master and the slaves.
6.4.2 DC configuration in the Inverter Drive 8400 (slave)
In order to use the DC synchronisation in the Inverter Drive 8400, select the sync source by means
of the standard device code C01120 :
Selection 4: MCI (synchronisation via MCI (communication module))

Note!
The synchronisation cycle time ...
• must be an integer multiple of 1 ms;
• may be maximally 15 ms.

Note!
The settings of the parameter sync cycle time (C01121), sync phase position (C01122),
sync tolerance (C01123) and sync PLL increment (C01124) common for the Lenze system
bus (CAN) cannot be made for EtherCAT. These values are automatically calculated by
the EtherCAT communication module and set internally in the inverter.
