EFB BAUD RATE
1.2, 2.4, 4.8, 9.6, 19.2,
Defines the communication speed of
38.4, 57.6, 76.8 kb/s
the RS485 link in kbits per second (kb/s).

EFB PARITY
0…3
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 = 8
NONE
1 – 8 data bits, no parity, one stop bit.
1 = 8
NONE
2 – 8 data bits, no parity, two stop bits.
2 = 8
EVEN
1 – 8 data bits, even parity, one stop bit.
3 = 8
ODD
1 – 8 data bits, odd parity, one stop bit.
5305
EFB CTRL PROFILE
0…2
Selects the communication profile used by the EFB protocol. No effect
on BACnet behavior.
0 =
ABB
DRV
LIM
– Operation of the Control Word and Status Word
conforms to ABB Drives Profile, as used in ACS400.
1 =
DCU
PROFILE
– Operation of Control/Status Words conforms to 32-bit
DCU Profile.
2 =
ABB
DRV
FULL
– Operation of Control/Status Words conforms to ABB
Drives Profile, as used in ACS600/800.

EFB OK MESSAGES
0…65535
Contains a count of valid messages received by the drive.
• During normal operation, this counter is increasing constantly.
5307
EFB CRC ERRORS
0…65535
Contains a count of the messages with a CRC error received by the
drive. For high counts, check:
• Ambient electro-magnetic noise levels – high noise levels generate
errors.
• CRC calculations for possible errors.
5308
EFB UART ERRORS
0…65535
Contains a count of the messages with a character error received by the
drive.
