CDS: Command data set

The BICO parameters are combined (binector and connector inputs) in a command data set
(CDS). These parameters are used to interconnect the signal sources of a drive.
By parameterizing several command data sets and switching between them, the drive can
be operated with different pre-configured signal sources.
A command data set contains the following (examples):
● Binector inputs for control commands (digital signals)
– ON/OFF, enable signals (p0844, etc.)
– Jog (p1055, etc.)
● Connector inputs for setpoints (analog signals)
– Voltage setpoint for V/f control (p1330)
– Torque limits and scaling factors (p1522, p1523, p1528, p1529)
A drive object can – depending on the type – manage up to 4 command data sets. The
number of command data sets is configured with p0170.
The following parameters are available for selecting command data sets and for displaying
currently selected command data sets - e.g. in the vector mode:
Binector inputs p0810 to p0811 are used to select a command data set. They represent the
number of the command data set (0 to 3) in binary format (where p0811 is the most
significant bit).
● p0810 BI: Command data set selection CDS bit 0
● p0811 BI: Command data set selection CDS bit 1
If a command data set that does not exist is selected, the current data set remains active.
The selected data set is displayed using parameter (r0836).
Note
When using standard telegrams in command data records, make sure that you do not
change telegram interconnections as this may lead to inconsistent behavior otherwise. If you
wish to change telegram interconnections, please assign the telegram selection with 999
(free telegram).
