ABB ACS880-104

Parameters 395
60.08 M/F comm loss
timeout
Sets a timeout for master/follower (DDCS) communication. If
a communication break lasts longer than the timeout, the
action specified by parameter 60.09 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.
100 ms
0…65535 ms Master/follower communication timeout.
60.09 M/F comm loss
function
Selects how the drive reacts to a master/follower
communication break.
Fault
No action No action taken. 0
Warning The drive generates an A7CB MF 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.
1
Fault Drive trips on 7582 MF 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.
2
Fault always Drive trips on 7582 MF comm loss. This occurs even though
no control is expected from the master/follower link.
3
60.10 M/F ref1 type Selects the type and scaling of reference 1 received from the
master/follower link. The resulting value is shown by 03.13
M/F or D2D ref1.
Auto
Auto Type 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).
0
Transparent No scaling is applied. 1
General Generic reference with a scaling of 100 = 1 (ie. integer and
two decimals).
2
Torque The scaling is defined by parameter 46.03 Torque scaling.3
Speed The scaling is defined by parameter 46.01 Speed scaling.4
Frequency The scaling is defined by parameter 46.02 Frequency scaling.5
60.11 M/F ref2 type Selects the type and scaling of reference 2 received from the
master/follower link. The resulting value is shown by 03.14
M/F or D2D ref2.
For the selections, see parameter
60.10 M/F ref1 type.
Torque
60.12 M/F act1 type Selects the type/source and scaling of actual value ACT1
transmitted to the master/follower link.
Auto
Auto Type/source and scaling follow the type of reference 1
selected by parameter 60.10 M/F ref1 type. See the individual
settings below for the sources and scalings.

Torque 01.10 Motor torque is sent as actual value 1. The scaling is
defined by parameter 46.03 Torque scaling.
3
Speed 01.01 Motor speed used is sent as actual value 1. The scaling
is defined by parameter 46.01 Speed scaling.
