This parameter changes the polling time of the first data set. The
default value (1) indicates that the first data set pair (usually DS1 and
DS2) are sent during every polling sequence (every 6 milliseconds).
These parameters change the polling times of the second pair of data
sets (usually DS3 and DS4) and third data set pair (usually DS5 and
DS6) respectively. Allowable values are 1 to 32767, one unit
corresponding to 6 milliseconds.
Normally, data sets DS1, DS3 and DS5 are sent by the master to the
drive, whereas data sets DS2, DS4 and DS6 are sent by the drive to
the master. The starting data set number can be offset by using this
parameter.
The first data set number used equals the value of this parameter; e.g.
if this parameter is set to 1, the first data set to be used is DS1.
By default, the value of this parameter is 1, thus the first data set used
is DS1.
ABB drives can receive control information from multiple sources
including digital inputs, analogue inputs, the drive control panel and a
communication module (e.g. NCSA-01). ABB drives allow the user to
separately determine the source for each type of control information
(Start, Stop, Direction, Reference, Fault Reset, etc.). In order to give
the fieldbus master station the most complete control over the drive,
the communication module must be selected as source for this
information. See the user documentation of the drive for information on
the selection parameters.
