Follower mask 1. 1 = 1
57.05 Follower mask 2 On the master drive, selects the followers to be polled. If no
response is received from a polled follower, the action
selected by parameter 57.02 Comm loss func is taken.
The least significant bit represents follower with node address
32, while the most significant bit represents follower 62.
When a bit is set to 1, the corresponding node address is
polled. For example, followers 32 and 33 are polled when this
parameter is set to the value of 0x3.

Follower mask 2. 1 = 1
57.06 Ref 1 src Selects the source of D2D reference 1 sent to the followers.
The parameter is effective on the master drive, as well as
intermediate followers in a multicast message chain (see
parameter 57.11 Ref1 msg type)..
Pointer Value pointer setting (see Terms and abbreviations on page
63).
-
57.07 Ref 2 src On the master drive, selects the source of D2D reference 2
broadcast to all followers.
Pointer Value pointer setting (see Terms and abbreviations on page
63).
-
57.08 Follower cw src Selects the source of the D2D control word sent to the
followers. The parameter is effective on the master drive, as
well as intermediate followers in a multicast message chain
(see parameter 57.11 Ref1 msg type)..
Pointer Value pointer setting (see Terms and abbreviations on page
63).
-
57.11 Ref1 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,
i.e. 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 intermediate followers (i.e.
followers relaying the message to other followers), the
sources for the control word and reference 1 are selected by
parameters 57.08 Follower cw src and 57.06 Ref 1 src
respectively.
Note: Reference 2 is broadcast to all followers.
Broadcast 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.
0
Ref1 MC Grps The drive-to-drive control word and reference 1 are only sent
to the drives in the multicast group specified by parameter
57.13 Next ref1 mc grp. This setting can also used in
intermediate followers to form a multicast chain.
1
57.12 Ref1 mc group Selects the multicast group the drive belongs to. See
parameter 57.11 Ref1 msg type.
