1 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:
ï‚· Speed reference value
ï‚· Torque reference value
ï‚· Switch between speed and torque reference values during operation
ï‚· 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.
Buttons with red arrows have been added for easier navigation through the
assistant:
Figure 1-1
The buttons make it easier to alternate between pages related to the same
subject (e.g., along the reference value path or to select binary inputs as
sources for signals).
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.

3 Selecting the Type of Ref. Value
Information that you will find in this chapter …
This chapter gives you information on,
ï‚· what a reference value is and the types of reference values which are
provided by the Comfort Reference Value application,
ï‚· how to select the type of reference value and
further details for the types of reference values are present.
Types of reference values
The type of motor control is called the type of reference value. The Comfort
Reference Value application offers you a choice of the following types of
reference values:
ï‚· Speed reference value (i.e., control of the motor speed). A speed reference
value is used for belt drives, pumps and fans, for example.
ï‚· Torque reference value (i.e., control of the torque). A torque reference value
is used for insertion and for screw driving, for example.
ï‚· Switching between speed and torque reference value (i.e., switching
between speed and torque control during operation). Switching between
controls is used for pressure rollers, for example.
ï‚· Switching between master/slave drive (i.e., switching from an internal
reference value to a master reference value). The internal reference value is
always used as speed reference value. The external reference value can be
used as the torque or speed reference value. This type of reference value is
used, for example, for a multiple-axis network with slaves which can be
turned off.

How to switch between speed and torque reference values
If you choose to switch controls during operation, page 1 of the Assistant
indicates the parameter D112 (Figure 3-2). In Selector D112 select a signal
source (binary input or fieldbus parameter). You can then switch between the
types of control during operation with this signal. Speed control is used for a
low level while torque control is used for a high level..

How to switch between master/slave drive
If you use the switchover between master and slave drive, the parameter D111
and additional option boxes appear (Figure 3-3). Select a signal source in this
parameter (binary input or fieldbus parameter). You can then switch between
master and slave during operation with this signal. The internal speed
reference value is used for a low level. With a high level the drive uses the
master reference value.
With the other option boxes you can choose a speed/speed or torque/speed
switchover. If you use the torque/speed switchover the master reference value
is evaluated as the torque reference value.
Figure 3-3 Setting for the master/slave drive switchover
Details
Page 1 of the Comfort Reference Value Assistant affects the parameter C61.
This parameter is used to specify whether speed or torque control will be used.
With a speed reference value, C61 is set to 0:inactive. With a torque reference
value, C61 is set to 1:active.
When switching between speed and torque control is used the switch is made
with the signal selected in D112.
When the type master/slave drive reference value is used with the switchover
speed/speed, C61 is set to 0:inactive. With the speed/torque switchover, C61 is
set to 1:active. The specification of whether torque control or speed control is to
be used is made with the signal selected in D111. Speed control is used with a
low level while torque control is used with a high level.

4 Representing the Reference
Values in User Units
Information that you will find in this chapter …
This chapter gives you information on:
ï‚· what user units are,
ï‚· how to scale your reference value in user units
User units
To simplify presentation, reference values can be indicated in user units in the
Comfort Reference Value application (e.g., bottles per second on a bottle
conveyor belt). All ratios of the motor speed are covered by this.
The user units are calculated in the Comfort Reference Value Assistant. Since
calculation depends on the type of reference value used, go to page 1. Type of
Reference Value first and select one of the options offered there. After that you
can perform the calculation on the next page.
Calculation of each type of reference value is described in a separate section
below.
Information
Remember that scaling only has to be performed when you want
to present display values in user units.
If presentation in rpm units is sufficient, the scaling described in
the next few sections is unnecessary. If this is the case, skip
chapter 4 and continue reading in chapter 5.

4.1 User Units with a Speed Reference Val.
Information that you will find in this section …
This section describes how to scale a speed reference value in user units.
Before you can begin scaling you must have activated the speed reference
value on page 1 of the Assistant.
Scaling the reference value
Figure 4-1 shows page 2.1 of the Assistant. It presents the organization of a
machine with motor, gear unit and other ratios.
Figure 4-1 Scaling for the speed-type reference value
First, edit the parameters on the top of the page (Figure 4-2):
ï‚· In D86 specify the number of decimal digits with which speeds are to be
represented.
ï‚· In D89 enter the desired unit of measurement for the speed (e.g.,
compartments per second). Remember that not more than 8 characters can
be entered.
ï‚· Activate the option box as per your entry in D89 so that the time reference
can be correctly calculated internally.
Example: You have entered compartments/second in D89. In this case you
would activate the option box /sec.
