Description
Selects the node address of the drive for communication with
the external controller. No two nodes on-line may have the
same address.
With an AC 800M (CI858) DriveBus connection, drives must
be addressed 1...24; with an AC 80 DriveBus connection,
drives must be addressed 1...12. Note that the BusManager
function must be disabled in the DriveBus controller.
With optical ModuleBus, the drive address is set according to
the position value as follows:
1. Multiply the hundreds of the position value by 16.
2. Add the tens and ones of the position value to the result.
For example, if the position value is 101, this parameter must
be set to 1×16 + 1 = 17.
Node address.
Selects the topology of the fiber optic link with an external
controller.
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.
Selects the communication speed of the channel selected by
parameter 60.51 DDCS controller comm
1 megabit/second.
2 megabit/second.
4 megabit/second.
8 megabit/second.
Defines the light intensity of the transmission LED of RDCO
module channel CH0. (This parameter is effective only when
parameter 60.51 DDCS controller comm port
CH 0. 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 fiber optic
master/follower link (page 38).
