15. Appendix 5 – Fieldbus parametrisation
The following chapter describes briefly how to parametrise
the AC drive in order for the motor to be controllable via
fieldbus. These instructions are written for basic applications.
For more information, consult the application-specific manual.
In order for the AC drive to accept commands from the
fieldbus network, the control place of the AC drive has to be
set to fieldbus. The default value of the parameter “Control
Place” is usually I/O. Note that if the control unit firmware is
updated, the default settings are restored. In addition, some
applications may have the remote speed reference selection
set by default to other than fieldbus. In these cases, the
speed reference selection must be set to fieldbus, in order
for the speed reference to be controlled via fieldbus.
otee: N The motor control mode should be selected to
support the used process and profile.
15.1 Fieldbus control and basic reference selection
The following tables list some of the parameters related
to fieldbus control in case of the standard application,
the Eaton MMX, for use via fieldbus. See the application
specific manuals for more detailed information.
Parameters can be read and written by using the drive
panel, PC Tools or fieldbus protocol. Table below contains
links to chapters where the ID value reading is described.

(multipurpose application)
Parameter name ID Value Default Panel tree
Motor control mode 600
0 = Frequency
1 = Speed
2 = Torque
0 P 2.6.1
Control place selection 125 3 = Fieldbus 1 P 3.1
Fieldbus Ctrl Ref. 122 9 = Fieldbus 3 P 2.1.13
15.2 Torque control parametrization
Some extra parametrisation has to be made in order
to control the frequency control with torque control.
The following instructions are for the Eaton SPX
application, see the application-specific manual for
more detailed information.
•
Motor control mode (ID 600) should be configured
to “Torque control” (2)
To configure the drive to use correct torque reference,
select the parameter “Torque Reference Selection”
to ProcessDataIn1 (9). This can be done with:
•
PC-tool or panel
•
