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:

 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.

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:

Introduction

Comfort Reference Value

ID 441843.05

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,

 what a reference value is and the types of reference values which are

provided by the Comfort Reference Value application,

 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:

 Speed reference value (i.e., control of the motor speed). A speed reference

value is used for belt drives, pumps and fans, for example.

 Torque reference value (i.e., control of the torque). A torque reference value

is used for insertion and for screw driving, for example.

 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.

 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:

 what user units are,

 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):

 In D86 specify the number of decimal digits with which speeds are to be

represented.

 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.

 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.
