Parameterizing the function
Parameter
Description
P0700 = 2
Controls the motor using the digital inputs of the inverter
P0701 = 1
The motor is power-up with digital input 0 (factory setting)
Further options:
The motor can be powered-up with any other digital input, e.g. with digital input 3 via
P0704 = 1
P0702 = 12
The motor is reversed with digital input 1 (factory setting)

Command sources
The command source is the interface via which the inverter receives its control commands.
The following interfaces are available:
● Digital inputs
● Fieldbus
Note
The "Get master control" or "Manual/Auto changeover" function can also be used to
specify commands and setpoints via STARTER or the Operator Panel.
Change command source
You selected the command source in the basic commissioning. If you must subsequently
change the command source, set the following parameters:
P0700
= 2
Digital inputs,
factory setting for inverters without PROFIBUS interface.
= 6
Fieldbus,
factory setting for inverters with PROFIBUS interface.
Digital inputs as command source
If you wish to control the motor via digital inputs, select one of the two following options:
1.
You use the factory settings for the digital inputs. Additional information is available in the
section Wiring examples for the factory settings (Page 64).
2.
You adapt the function of the digital inputs to your application. How you do this is
described in Section Digital inputs (Page 93).
