Operation
9.1 Basic information
It is possible to parameterize several drive data sets. You can switch easily between different
drive configurations (control type, motor, encoder) by selecting the corresponding drive data
set.
A drive object can manage 4 drive data sets.
Binector inputs p0820 and p0821 are used to select a drive data set. They represent the
number of the drive data set (0 to 3) in binary format (where p0821 is the most significant
bit).
● p0820 BI: Drive data set selection DDS, bit 0
● p0821 BI: Drive data set selection DDS, bit 1
EDS: Encoder data set
An encoder data set contains various adjustable parameters for the connected encoder that
are relevant for configuring the drive.
● Adjustable parameters, e.g.:
– Encoder interface component number (p0141)
– Encoder component number (p0142)
– Encoder type selection (p0400)
The parameters that are grouped together in the encoder data set are identified in the
parameter list by "EDS" and are provided with index [0...n].
A separate encoder data set is required for each encoder controlled by the Control Unit. Up
to 2 encoder data sets are assigned to a drive data set via parameters p0187 and p0188.
It is only possible to switch an encoder data set by means of a DDS switchover. When a
drive data set is selected, the assigned encoder data sets are selected automatically.
