264 Parameters
60.02 M/F node address Selects the node address of the drive for master/follower
communication. No two nodes on-line may have the same
address.
Note: The allowable addresses for the master are 0 and 1.
The allowable addresses for followers are 2…60.
1
1…254 Node address.
60.03 M/F mode Defines the role of the drive on the master/follower or drive-to-
drive link.
Not in use
Not in use Master/follower functionality not active. 0
DDCS master The drive is the master on the master/follower (DDCS) link. 1
DDCS follower The drive is a follower on the master/follower (DDCS) link. 2
D2D master Not supported by ACS860. 3
D2D follower Not supported by ACS860. 4
DDCS forcing The role of the drive on the master/follower (DDCS) link is
defined by parameters 60.15 Force master and 60.16 Force
follower.
5
D2D forcing Not supported by ACS860. 6
60.05 M/F HW connection Selects the topology of the master/follower link.
Note: Use the setting Star if using the master/follower
functionality (see page 30) through the XD2D connector (as
opposed to a fiber optic link).
Ring
Ring The devices are connected in a ring topology. Forwarding of
messages is enabled.
0
Star The devices are connected in a star topology (for example,
through a branching unit). Forwarding of messages is
disabled.
1
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.
