Fieldbus as setpoint
source:
The speed setpoint is
specifed via the fieldbus.
Analog input as setpoint
source:
The speed setpoint is
specifed via an analog
input.
- Examples
Fieldbus as command
source:
The motor is switched
on/off via the fieldbus.
Digital inputs as
command source:
The motor is switched
on/off via digital inputs.

Parameters P0810 and P0811 are connected to control commands (e.g. the digital inputs of
the inverter) by means of BICO parameterization.
Table 5- 17 Parameters for switching the command data sets:
Parameter Description
P0810 = … 1st control command for switching the command data sets
Example: When P0810 = 722.0, the system switches from command data set 0 to
command data set 1 via digital input 0.
P0811 = … 2nd control command for switching the command data sets
r0050 Displaying the number of the CDS that is currently active
A copy function is available making it easier to commission more than one command data set:
P0809.0 = … Number of the command data set to be copied (source)
P0809.1 = … Number of the command data set to which the data is to be copied (target)
P0809.2 = 1 Start copying
For an overview of all the parameters that belong to the drive data sets and can be switched,
