Communication Set-up – EFB
Serial Communication Selection
To activate the serial communication, set parameter 9802
COMM PROTOCOL SEL =
• 1 (STD MODBUS). The MD4 must be set here with
MicroTech III control.
• 2 (N2)
• 3 (FLN)
• 5 (BACNET)
NOTE: If you cannot see the desired selection on the panel,
your drive does not have that protocol software in the
application memory.
Serial Communication Conguration
Setting 9802 automatically sets the appropriate default values
in parameters that dene the communication process. These
parameters and descriptions are dened below. In particular,
note that the station Id may require adjustment.

Code Description
EFB Protocol Reference
Modbus N2 FLN BACnet
5301 EFB PROTOCOL ID Contains the identication 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 Denes the node address of the
RS485 link.
Set each drive on the network with a unique value for this
parameter. When this protocol is selected, the default value for
this parameter is: 1 Note: For a new address to take affect, the
drive power must be cycled OR 5302 must rst be set to 0 before
selecting a new address. Leaving 5302 = 0 places the RS485
channel in reset, disabling communication..
Sets MS/TP MAC ID. A
temporary value of 0 places the
protocol channel in reset
5303 EFB BAUD RATE Denes 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
76.8 kbits/s
When this protocol is selected, the default value for this parameter is When this protocol is selected,
the default value for this
parameter is: 38400
9.6 9.6 4.8.
5304 EFB PARITY Denes the data length, parity
and stop bits to be used with the RS485 link
communication.
The same settings must be used in all on-line
stations.
0 = 8N1 – 8 data bits, No parity, one stop bit.
1 = 8N2 – 8 data bits, No parity, two stop bits.
2 = 8E1 – 8 data bits, Even parity, one stop bit.
3 = 8O1 – 8 data bits, Odd parity, one stop bit.
When this protocol
is selected, the
default value for this
parameter is: 1
When this protocol is selected, the default value for this parameter is: 0
Sets MS/TP character format.
5305 EFB CTRL PROFILE Selects the communication
prole used by the EFB protocol.
0 = ABB DRV LIM – Operation of Control/Status
Words conform to ABB Drives Prole, as used in
ACH400.
1 = DCU PROFILE – Operation of Control/Status
Words conform to 32-bit DCU Prole.
2 = ABB DRV FULL – Operation of Control/Status
Words conform to ABB Drives Prole, as used in
ACH600/800.
When this protocol
is selected, the
default value for this
parameter is: 0
N/A. When this protocol is selected, the default value for this parameter is: 0.
Changing the value for this parameter has no affect on this protocol’s behavior.
