Specifying the motor speed via the fieldbus

If you enter the setpoint via a fieldbus, you must connect the inverter to a higher-level
control. For additional information, see chapter Configuring the fieldbus (Page 101).
Interconnecting the fieldbus with the setpoint source
You have two options for using the fieldbus as the setpoint source:
1. Using p0015, select a configuration that is suitable for your application.
2. Interconnect main setpoint p1070 with the fieldbus.
