IEDLBUS PARAMETRIZATION
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.
NOTE! The motor control mode should be selected to support the used process and profile.
The navigation path to the fieldbus parameters may differ from application to application. The
exemplary paths below apply to the VACON
®
100 family AC drive.
5.1 Fieldbus control and basic reference selection
The following tables list some of the parameters related to fieldbus control in case of VACON
®
applications for the VACON
®
100 family AC drive. See the application specific manuals for more
detailed information.
Parameters can be read and written by using the drive panel, PC Tool or fieldbus protocol. See
Chapter 6.3.5 for reading and writing application parameters over Modbus. Notice that some of
connection parameters for fieldbus may need to be set (depending on your configuration) via panel
or PC tool, before you can connect over fieldbus and write application parameters.
5.1.1 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 VACON
®
100 family AC drives, see the application
specific manual for more detailed information.
• Motor control mode (ID 600) must 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 in panel
tree: P 3.3.2.1, ID 64
