Description
Channel 0 on RDCO module (with BCU control unit only).
Connector XD2D.
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
port.
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
is set to RDCO 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
functionality (page 72).
