8.2 Data Sets
Description
For many applications it is advantageous if several parameters can be simultaneously
changed, during operation or in the ready state, using an external signal.
This functionality can be elegantly implemented using indexed parameters. In this case, as
far as the functionality is concerned, the parameters are combined to form groups/data sets
and are indexed. By using indexing, several different settings can be saved for each
parameter which can be activated by changing-over the data set (i.e. toggling between
indexes).
The following data sets apply:
● Command Data Set CDS
● Drive Data Set DDS
Three independent settings are possible for each data set. These settings can be made
using the index of the particular parameter:
● CDS0 ... CDS2
● DDS0 ... DDS2
Command Data Set
Those parameters (connector and binector inputs) which are used to control the inverter and
enter a setpoint, are assigned to the command data set (CDS). The signal sources for the
control commands and setpoints are interconnected using BICO technology. For that the
connector and binector inputs are assigned corresponding to the connector and binector
outputs as signal sources. A command data set includes:
Command sources and binector inputs for control commands (digital signals) e.g.
Selects the command source
ON/OFF1
OFF2
JOG Enable
Enable JOG right
Enable JOG left
Setpoint sources and connector inputs for setpoints (analog signals) e.g.
Selection of frequency setpoint
Selection of main setpoint
Selection of additional setpoint
