Code Description
5303 EFB BAUD RATE
Defines the communication speed of
the RS485 link in kbits per second (kb/s).
1.2 kb/s
2.4 kb/s
4.8 kb/s
9.6 kb/s
19.2 kb/s
38.4 kb/s
57.6 kb/s
76.8 kb/s
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 = 8 1 – 8 data bits, no parity, one stop bit.
NONE
1 = 8 2 – 8 data bits, no parity, two stop bits.
NONE
2 = 8 1 – 8 data bits, even parity, one stop bit.
EVEN
3 = 8 1 – 8 data bits, odd parity, one stop bit.
ODD
5305 EFB CTRL PROFILE
Selects the communication profile used by the EFB protocol. No effect
on BACnet behavior.
0 =
ABB DRV LIM
conforms to ABB Drives Profile, as used in ACS400.
1 =
DCU PROFILE
DCU Profile.
2 =
ABB DRV FULL
Drives Profile, as used in ACS600/800.
5306 EFB OK MESSAGES
Contains a count of valid messages received by the drive.
• During normal operation, this counter is increasing constantly.
5307 EFB CRC ERRORS
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
Contains a count of the messages with a character error received by the
drive.
