2 INTRODUCTION
Introduction
The Comfort Reference Value application gives you a wide variety of functionalities for
speed and torque operation. You can select from the following available types of
reference values:
• Speed reference value
• Torque reference value
• Switch between speed and torque reference values during operation
• Switch between master/slave drive (i.e., the switch between an internal speed
reference value and the reference value of a master drive or in other words a master
reference value). The master can specify a speed or a torque reference value. The
internal reference value is always a speed reference value.
Reference value interfaces such as analog reference values, preset reference values or
motor potentiometers are available for the different types of reference values. In addition
you can use skip-speeds, comparators and other supplemental functions.
The Comfort Reference Value
Assistant
Since this description is based on the structure of the Comfort Reference Value
Assistant, STÖBER Antriebstechnik recommends studying the Assistant together with
this description for better comprehension.
To access the Assistant, open the Comfort Reference Value application in POSITool.
Input and output signals
You will find comprehensive information on input and output signals in the signal tables
at the end of some of the sections. The signal tables are organized as follows.
Binary input signals
In addition to the designation and a description the signal tables for binary inputs contain
the selection parameter (Selector) in which you can set the signal source. You can
choose between a binary input or fieldbus (setting 2:parameter). If you select fieldbus the
column Fieldbus Image shows you the address to which you write the signal.
The column Display Parameter shows you the signal status regardless of the source
which is set in the selector.
In addition a switch-on or switch-off delay can be parameterized for some of the binary
input signals. You will find the parameters in which the delay times are to be entered in
the column Time ON or Time OFF.
Analog input signals
In addition to the designation and description you will also find the specification of
Selector, Fieldbus Image and Display Parameter for analog input signals. You can
use the parameter specified as Fieldbus image to obtain a constant value during
operation. Set the Selector to 4:parameter and enter the desired value in this parameter.
The link to a fieldbus system is not necessary in this case.
In addition a characteristic curve scaling can be performed for some of the signals. You
will find the scaling parameters in the Scaling column. The applicable description
explains how to perform characteristic curve scaling.
Status signals
The designation and description are also to be found in the tables of the binary status
signals. The column Fieldbus Image shows the address from which the signal can be
read via fieldbus. The column Single Parameter gives you the parameter to be used to
indicate the signal on a binary output.
