No.
100 ms / uint16Sets a timeout for master/follower (DDCS) communication.
If a communication break lasts longer than the timeout, the
action specified by parameter 60.9 M/F comm loss function
is taken.
As a rule of thumb, this parameter should be set to at least
3 times the transmit interval of the master.

Fault / uint16Selects how the drive reacts to a master/follower
communication break.

The drive generates an A7CB M/F comm loss warning.
This only occurs if control is expected from the
master/follower link, or if supervision is forced using
parameter 60.32 M/F comm supervision force.
WARNING!
Make sure that it is safe to continue operation in
case of a communication break.

Drive trips on 7582 M/F comm loss. This only occurs if
control is expected from the master/follower link, or if
supervision is forced using parameter 60.32 M/F comm
supervision force.

Drive trips on 7582 M/F comm loss. This occurs even
though no control is expected from the master/follower link.

Auto / uint16Selects the type and scaling of reference 1 received from
the master/follower link. The resulting value is shown by
3.13 M/F or D2D ref1.
M/F ref1 type60.10
0Type and scaling are chosen automatically according to
which reference chain (see settings Torque, Speed,
Frequency) the incoming reference is connected to. If the
reference is not connected to any chain, no scaling is
applied (as with setting Transparent).

1No scaling is applied.Transparent
2Generic reference with a scaling of 100 = 1 (ie. integer and
two decimals).

Torque / uint16Selects the type and scaling of reference 2 received from
the master/follower link. The resulting value is shown by
3.14 M/F or D2D ref2.
For the selections, see parameter 60.10 M/F ref1 type.

Auto / uint16Selects the type/source and scaling of actual value ACT1
transmitted to the master/follower link.
