14. APPENDIX 4 - FIELDBUS PARAMETRISATION
The following chapter describes briefly how to parametrize 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.
14.1 Fieldbus control and basic reference selection
