5303 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).

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 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.

5306 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.
