Description
DDCS (fiber optic) communication configuration.
Fiber optic links connected to DDCS channels can be used to
• connect drives together to build a master/follower network
• connect the drive to an external controller such as the
AC 800M.

External controller interface
Selects the DDCS channel used for master/follower
communication.
None (communication disabled).
Channel A on FDCO module in slot 1.
Channel A on FDCO module in slot 2.
Channel A on FDCO module in slot 3.
Channel B on FDCO module in slot 1.
Channel B on FDCO module in slot 2.
Channel B on FDCO module in slot 3.
Channel 2 on RDCO module (with BCU control unit only).
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.
Node address.
Defines the role of the drive on the master/follower link.
Master/follower link not active.
The drive is the master on the master/follower link.
The drive is a follower on the master/follower link.
Selects the topology of the master/follower link.
The devices are connected in a ring topology. Forwarding of
messages is enabled.
The devices are connected in a star topology (for example,
through a branching unit). Forwarding of messages is
disabled.
Defines the light intensity of the transmission LED of RDCO
module channel CH2. (This parameter is effective only when
parameter 60.01 M/F communication port
CH2. FDCO modules have a hardware transmitter current
selector.)
In general, use higher values with longer fiber optic cables.
The maximum setting is applicable to the maximum length of
the fiber optic link. See Specifications of the master/follower
link (page 34).
Light intensity.
Sets a timeout for master/follower communication. If a
communication break lasts longer than the timeout, the action
specified by parameter 60.09 M/F comm loss function
taken.
