If you cannot see the desired selection on the panel, your drive does not have
that protocol software in the application memory.
Serial Communication Configuration
Setting 9802 automatically sets the appropriate default values in parameters that
define the communication process. These parameters and descriptions are defined
below. In particular, note that the station Id may require adjustment.

5301
EFB PROTOCOL ID
Contains the identification and
program revision of the
protocol.
Do not edit. Any non-zero value entered for parameter
9802 COMM PROT SEL, sets this parameter automatically.
The format is: XXYY, where xx = protocol ID, and YY =
program revision.
5302
EFB STATION ID
Defines the node address of
the RS485 link.
Set each drive on the network with a unique value for this
parameter.
Note:
For a new address to take affect, the drive power
must be cycled
OR
5302 must first be set to 0 before
selecting a new address. Leaving 5302 = 0 places the
RS485 channel in reset, disabling communication.
5303
EFB BAUD RATE
Defines the communication
speed of the RS485 link in
kbits per second (kbits/s).
1.2 kbits/s
2.4 kbits/s
4.8 kbits/s
9.6 kbits/s
19.2 kbits/s
38.4 kbits/s
57.6 kbits/s
Setting (9.6) is default when protocol is
selected.
Setting (4.8)
is default
when
protocol is
selected. Do
not edit.
