After making the additional adjustments and checking the I/O
connections, use the Diagnostics menu to make sure that the setup is
functioning correctly. In the Main menu, select Diagnostics and press

Motor overload protection
The motor thermal overload protection is set to motor current and motor class curves as default. Motor thermal overload
protection can also be measured using motor temperature devices or can be estimated using a motor model defined by
parameters. To enable protection using motor model parameters or measurement devices set parameter 35.11 and
subsequent parameters through 35.55. To adjust motor class curves (default is class 20), change parameters 35.56 and
35.57.
?
Use the information key ( ) on the drive control panel for more information on setting group 35 parameters. You must set
the drive overload parameters correctly, or motor damage could occur.
Fieldbus communication
To configure the embedded fieldbus communication for BACnet MSTP, you must set at least these parameters:

Description
Embedded
Selects fieldbus as the source for the start and stop commands when
fieldbus
EXT1 is selected as the active control location.
EFB ref1
Selects a reference received through the embedded fieldbus interface
as speed reference 1. Use this parameter with the vector motor
control mode.
EFB ref1
Selects a reference received through the embedded fieldbus interface
as frequency reference 1. Use this parameter with the frequency motor
control mode.
BACnet MSTP
Initializes embedded fieldbus communication.
1 (default)
Node address. There must be no two nodes with the same node
address online.
19.2 kbps (default) Defines the communication speed of the link. Use the same setting as
in the master station.
8 EVEN 1 (default)
Selects the parity and stop bit setting. Use the same setting as in the
master station.
Refresh settings
Validates any changed EFB configuration settings. Use this after
changing any parameters in group 58.

Description
Warning: Current calibration is done at the next start.
Fault: Output phase current measurement fault.
The output current is more than the internal limit. This can also be caused by
an earth fault or phase loss.
A load unbalance that is typically caused by an earth fault in the motor or the
motor cable.
There is a short-circuit in the motor or the motor cable.
The intermediate DC circuit voltage oscillates due to missing input power
line phase.
