Next, activate controller synchronization in the EtherCAT
®
network. To do so, make the
following parameter settings (see the following figure):
• P887 Synchronization ext. controller = ON
• P888 Synchronization time SBus [ms] = 1
The synchronization time must correspond exactly with the bus cycle.
• P916 Ramp type = "Position interpolation 16 bit"
• P970 DPRAM Synchronization = YES
• P971 Synchronization phase = 0
P971 can be used to optimize the phase angle if aliasing occurs. Set a phase angle
of 0 ms as standard.

master settings
For time slice synchronization, you must activate the function Distributed Clock. The bus
cycle must correspond exactly with the synchronization time set in parameter P888. You
should also activate the watchdog for timeout monitoring for the Sync Manager 0x1000
(Output Data) only.
Make sure you deactivate the fixed PDO (InputData1 and OutputData1).
