316 Control through the embedded fieldbus interface
Setting the drive control parameters
After the embedded fieldbus interface has been set up, check and adjust the drive
control parameters listed in the table below. The Setting for fieldbus control column
gives the value or values to use when the embedded fieldbus signal is the desired
source or destination for that particular drive control signal. The Function/
Information column gives a description of the parameter.
Parameter Setting for
fieldbus control
Function/Information
CONTROL COMMAND SOURCE SELECTION
10.01 Ext1 start func FB Selects fieldbus as the source for the start
and stop commands when EXT1 is selected
as the active control location.
10.04 Ext2 start func FB Selects fieldbus as the source for the start
and stop commands when EXT2 is selected
as the active control location.
10.10 Fault reset sel P.02.36.08 Selects the fault reset bit of signal 02.36
EFB main cw as the source for the fault reset
command of the drive.
Note: To start and stop the drive through control location EXT1, set parameter 10.01 to FB and
keep parameter 12.01 to its default value (C.FALSE).
SPEED REFERENCE SELECTION
21.01 Speed ref1 sel EFB ref1 or
EFB ref2
Selects a reference received through the
embedded fieldbus interface as the speed
reference ref1 of the drive.
21.02 Speed ref2 sel EFB ref1 or
EFB ref2
Selects a reference received through the
embedded fieldbus interface as the speed
reference ref2 of the drive.
Note: To control the drive speed with fieldbus reference REF1, set parameter 21.01 to EFB
ref1, and keep parameters 12.03 and 21.04 to their default values (Speed and C.FALSE).
TORQUE REFERENCE SELECTION
24.01 Torq ref1 sel EFB ref1 or
EFB ref2
Selects one of the references received
through the embedded fieldbus interface as
the torque reference ref1 of the drive.
24.02 Torq ref add sel EFB ref1 or
EFB ref2
Selects one of the references received
through the embedded fieldbus interface as
the torque reference ref2 of the drive.
Note: To control the torque of the drive with fieldbus reference REF2, set parameter 24.01 to
EFB ref2, keep 12.01 to its default value (C.FALSE) and set 12.03 to Torque.
REFERENCE SCALING
50.04 Fb ref1

Raw data
Torque
Speed
Defines the fieldbus reference REF1 scaling.
Selects also the fieldbus actual signal act1
when set to Torque or Speed
.
