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.
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 rst be set to 0 before selecting
a new address. Leaving 5302 = 0 places the RS485 channel in reset, disabling communication.
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 Do not edit. 4.8 Do not edit.
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 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.
