7.2 Data sets
CDS: command data set (CDS)
The BICO parameters (binector and connector inputs) are grouped together in a
Command Data Set. These parameters are used to interconnect the signal
sources of a drive (see Section 7.4).
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):
S Binector inputs for control commands (digital signals)
– ON/OFF, enable signals (p0844, etc.)
– Jog (p1055, etc.)
S Connector inputs for setpoints (analog signals)
– Voltage setpoint for V/f control (p1330)
– Torque limits and scaling factors (p1522, p1523, p1528, p1529)
One command data set is available for servo mode and two for vector mode.
The following parameters are available for selecting command data sets and for
displaying the currently selected command data set in vector mode:
Table 7-1 Command data set: selection and display
Selection Display
Bit 0 Selected Active
CDS p0810 r0836 r0050

If a command data set, which does not exist, is selected, the current data set re-
mains active.
