Communication Setup – EFB
Serial Communication Selection
To activate the serial communication, set parameter 9802
COMM PROTOCOL SEL =
• 1 (STD MODBUS) .
• 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 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 .

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 .
When one of these protocols is selected, the default value for this parameter is: 1
When this protocol is
selected, the default value
for this parameter is: 128
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
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 Do not edit .
4 .8 Do not edit .
5304
EFB PARITY
Defines 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 Do not edit .
NOTE:
For the BACnet protocol, the MD5 will function as
a Master with MAC IDs in the range of 1 - 127 . With
MAC ID settings of 128 - 254, the drive is in Slave
only behavior .
