57.09 KERNEL SYNC MODE
Determines which signal the time levels of the drive are synchronised with. An offset can be defined
by parameter
(0) NoSync
(1) D2DSync
(2) FBSync
(3) FBToD2DSync
57.10 KERNEL SYNC OFFS
Defines an offset in microseconds between the synchronisation signal received and the time levels of
the drive. With a positive value, the drive time levels will lag behind the synchronisation signal; with a
negative value, the drive time levels will lead.

57.11 REF 1 MSG TYPE
By default, in drive-to-drive communication, the master broadcasts the drive-to-drive control word and
references 1 and 2 to all followers. This parameter enables multicasting, ie, sending the drive-to-drive
control word and reference 1 to a certain drive or group of drives. The message can then be further
relayed to another group of drives to form a multicast chain.
In the master, as well as any submaster (ie, follower relaying the message to other followers), the
sources for the control word and reference 1 are selected by parameters
and
Note: Reference 2 is broadcast by the master to all followers.

if desired.
No synchronisation.
If the drive is the master on a drive-to-drive link, it broadcasts a
synchronisation signal to the follower(s). If the drive is a follower, it
synchronises its firmware time levels to the signal received from the
master.
The drive synchronises its firmware time levels to a synchronisation
signal received through a fieldbus adapter.
If the drive is the master on a drive-to-drive link, it synchronises its
firmware time levels to a synchronisation signal received from a
fieldbus adapter, and broadcasts the signal on the drive-to-drive link. If
the drive is a follower, this setting has no effect.

Synchronisation offset.
FW block: D2D COMMUNICATION
The control word and reference 1 are sent by the master to all
followers. If the master has this setting, the parameter has no effect in
the followers.
The drive-to-drive control word and reference 1 are only sent to the
drives in the multicast group specified by parameter
REF1 MC GRP. This setting can also be used in submasters
(followers in which parameters
REF1 MC GROUP are set to the same value) to form a multicast
chain.
