5.3 Command sources
5.3.1 Selecting command sources
Selecting the command source [P0700]
The motor is switched on/off via external inverter control commands. The following command
sources can be used to specify these control commands:
● Operator control / display instrument (Operator Panel)
● Digital inputs
● Fieldbus
The command sources available depend on the frequency inverter version.
● For frequency inverters with a fieldbus interface, the 'fieldbus' (P0700 = 6) is pre-selected
as the command source,
● For frequency inverters without a fieldbus interface, the digital inputs (P0700 = 2) are pre-
selected as command source.
