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 inverter version.

● For inverters with a fieldbus interface, the 'fieldbus' (P0700 = 6) is pre-selected as the

command source,

● For inverters without a fieldbus interface, the digital inputs (P0700 = 2) are pre-selected

as command source.

Table 5- 13 Parameters, to select the source for the inverter control commands
