Setting
Description
20.01 Ext1 commands
Embedded
fieldbus
Selects fieldbus as the source for the start and stop commands when
EXT1 is selected as the active control location.
22.11 Ext1 speed ref1
EFB ref1
Selects a reference received through the embedded fieldbus interface
as speed reference 1. Use this parameter with the vector motor control
mode.
26.11 Torque ref1 source
EFB ref1
Selects a reference received through the embedded fieldbus interface
as torque reference 1. Use this parameter with the vector motor
control mode.
28.11 Ext1 frequency ref1
EFB ref1
Selects a reference received through the embedded fieldbus interface
as frequency reference 1. Use this parameter with the frequency motor
control mode.
58.01 Protocol enable
Modbus RTU
Initializes embedded fieldbus communication.
58.03 Node address
1 (default)
Node address. There must be no two nodes with the same node
address online.
58.04 Baud rate
19.2 kbps (default) Defines the communication speed of the link. Use the same setting as
in the master station.
58.05 Parity
8 EVEN 1 (default) Selects the parity and stop bit setting. Use the same setting as in the
master station.

Description
A2A1
2281
Current calibration
Warning: Current calibration is done at the next start.
Fault: Output phase current measurement fault.
A2B1
2310
Overcurrent
The output current is more than the internal limit. This can also be caused by
an earth fault or phase loss.
A2B3
2330
Earth leakage
A load unbalance that is typically caused by an earth fault in the motor or the
motor cable.
A2B4
2340
Short circuit
There is a short-circuit in the motor or the motor cable.
-
3130
Input phase loss
The intermediate DC circuit voltage oscillates due to missing input power
line phase.
-
3181
Wiring or earth fault
Incorrect input and motor cable connection.
A3A1
3210
DC link overvoltage
Intermediate DC circuit voltage is too high.
A3A2
3220
DC link undervoltage
Intermediate DC circuit voltage is too low.
-
3381
Output phase loss
All three phases are not connected to the motor.
-
5090 STO hardware failure
STO hardware diagnostics has detected hardware failure. Contact ABB.
A5A0
5091
Safe torque off
The Safe torque off (STO) function is active.
A7CE
6681
EFB comm loss
Break in embedded fieldbus communication.
A7C1
7510
FBA A communication
Communication lost between drive (or PLC) and fieldbus adapter.
A7AB
-
Extension I/O
configuration failure
The installed C-type module is not the same as configured, or there is an
error in the communication between the drive and module.
