for the calculation of the drive solution.
• The »Drive Solution Designer« not only calculates the physical connections by means of formu-
las, but filters suggested solutions from the knowledge base according to different criteria.

1.3 Important information on the program

Why have we developed the DSD?
Drive systems become more and more powerful and have to be optimally adapted to mechatronic
requirements. The cost pressure in the field of engineering increases permanently. At the same
time, however, less time is available for planning, dimensioning, and selecting the drive system.
These high market requirements have motivated us to develop an efficient software which can carry out complex calculations of drive physics. The program is based on complex product knowledge
and can be easily used by every engineer. With the DSD you can solve your drive task professionally
in a few minutes and document it consistently. Like this, others are able to follow your calculations
anytime, too. Moreover, the DSD serves to optimise the application and the drive system regarding
energy efficiency.
Who has developed the DSD?
The program was developed by drive specialists and computer scientists in cooperation with experienced Lenze sales staff. The cooperation of this interdisciplinary development team makes it possible to carry out practically relevant dimensioning processes with the DSD.
Who has worked with the DSD so far?
Today, Lenze sales staff is working with DSD worldwide. Already since 2002 we have been gaining
experience with this kind of drive dimensioning program. On the basis of this experience the DSD
was advanced and optimised. Now we want to provide the program to a broad range of customers.
What is dimensioned with the DSD and what isn't?
A dimensioning includes the drive components: gearbox, motor, inverter, encoder on the motor
side, electrical brake units, regenerative power supply modules, and electromechanical brakes.
Further accessories as e. g. mains filters, automation modules, drive software etc. are not yet configured by the DSD at present and can for example be determined via the electronic catalogue Drive
Solution Catalogue (DSC).
• The Drive Solution Catalogue (DSC) can be found in the internet:

Who is responsible for the dimensioning result?
In the past years the DSD has stood the test of time during countless drive dimensioning processes.
In the context of our quality management the program is maintained continuously.

• The Application Knowledge Base (AKB) is an important means of support for your work with the
DSD.

All drive dimensionings with the DSD primarily are based on your default settings and the data that
you have entered. When the program-based calculations are carried out, we therefore depend on
correct and complete information by the customer. If our counselling services or program calculations are incorrect, unfeasible, or incomplete, and if this is due to incorrect and incomplete information by the respective user, liability by Lenze is excluded.
If error messages of the program cannot be eliminated by other entries, or if there are other doubts
during the use of the program, please consult your responsible Lenze sales representative at any
rate.
, free-of-charge service packs and updates
The dimensioning calculated by the DSD is based on general physical laws. If products of other manufacturers are used, of course Lenze does not give a warranty for their function. After all: The DSD
carries out physical drive dimensioning. Characteristics of the operational performance of a drive
solution therefore cannot be taken into consideration necessarily.

• At the beginning of the configuration a general drive train is displayed, consisting of the following components:
• Mains/environment
•Inverters
• Motor
•Gearbox
• Application
•Motion
• The components inverter and gearbox (with or without an additional drive element) are optional, i. e. their existence depends on the application or the dimensioning procedure.
• Therefore these components are displayed in an inactive manner at the beginning of the dimensioning. Depending on the further procedure the inverter or gearbox is displayed or removed from the drawing.
• Additionally, with regard to multi-axis applications, the drawing can be extended by a power
supply module (Master project) or by a place holder (Slave project).
• If an "Additional drive element" is used, this is symbolised by a toothed belt in the drawing, irrespective of the type selected.

5.1.1.1 Customer data
Customer data contain the data of the recipient of the protocol.
• In order to avoid a repeated specification of the data with regard to a further project for the
same customer, customer data is stored in an internal database in the DSD.
• The customer data are saved in a common data structure. They can only be created, altered, deleted, imported, exported, and selected together.
• After entering the data, the respective customer data set can be selected via a selection menu
next to the identifier "Customer", "Customer no.", "Contact person".
• If a selection from the list has been made, it can be rejected by the 'selection "All" '.
Tip!
The data in the login template can be called anytime by selecting "Login". Then you can alter the data in the login template.
Button Function
Import / export customer data Import or export of the customer data (database as a whole)
• An export enables the transfer/backup of a user's complete customer database. This can make sense if the DSD has to be uninstalled or the data
are to be provided to a third party.
• An import adopts the data of an external customer database to the DSD,
i. e. the existing customer database is completed by the imported customer data.

5.2.1 Displaying the project in the project viewer
A project that has been created with an older program version is not compatible to the current DSD
version. When it is opened in DSD, a query appears, asking you whether you want to display the
project with the integrated project viewer.
• You can open projects which have been created with a DSD version from 3.0 onwards.
• All dimensioning details of a DSD project are displayed.
• The navigation tree and result tree are provided as usual.
• It is not possible to make any changes to the dimensioning. Changes can only be carried out with
the DSD version by means of which the project has been created.
5.3 Saving the project
Save opened projects from time to time, in order to protect your work against power failures or system problems.
• In the Lenze setting the "Automatic saving" function is activated to save the project at regular
intervals. The function is executed in the background and can be set. Settings
• If you open the saved project in the DSD again later on, the dimensioning can be continued from
the point of saving.
• You can also skip back to any position in the navigation tree, e.g. to adapt an already available
solution for similar requirements.
How to save the current project:
Click the icon in the Toolbar, execute the command FileSave or press the <Ctrl>+<S>
keys.
• All pieces of information concerning the configured drive solution are saved.
• The file receives the extension *.dsd by default.

6.1 Data collection via checklists
The parameters of the application are important data without which a dimensioning process cannot be carried out. These parameters are marked in the check list with "*".
• The relevant data (e.g. mass, speed and motion) must be fully available.
• If less important data are missing (e. g. travelling resistances), you can make assumptions. Additionally document this in the dimensioning protocol.
To support the data collection, the DSD contains a checklist for each application, by means of which
you can collect the data of the application.
• The checklists can be printed.
• The checklists are accessed via the ToolsApplication checklist menu.
• A dialog box opens, by means of which you can select the appropriate application via option
fields.
• By clicking on Open the corresponding checklist is opened in Word.

6.2 Optimising drive solutions
DSD provides different functions for optimising drive dimensionings and finding a demand-oriented drive solution.
[6-1] Functions for optimising drive dimensionings
Creating alternatives and project comparison
Recommended use
• The drive should be dimensioned with alternative components. The process and motion data remain unchanged.
• An alternative to the current drive dimensioning can be created at any position in the navigation tree.
• You can compare the alternatives to the most important key data. The project comparison
can be printed.
Examples
• A drive dimensioning may require several alternatives to make a decision based on technical or
commercial considerations.
• We recommend several drive dimensioning with different components.
• The drive solution should be calculated with different reserves.
Application Tuner
Recommended use
• The drive should be dimensioned with different process and motion data. The components remain unchanged.

6.2.1 Creating an alternative
You can create alternatives to existing projects. A copy of the current project to the desired dimensioning step is created with a new file name. By the window technique of the DSD several projects
can be opened at the same time. The open projects can be arranged via the Windows menu.
There are two possibilities of creating alternatives in DSD:
A. Place the cursor in the desired position in the navigation tree of the current project. Now exe-
cute the Create alternative command using the right mouse button. A copy of the current
project up to the highlighted dimensioning step is created.
B. Complete the current project. Save it. Place the cursor in the desired position in the navigation
tree. With the command FileSave as the project is saved under a new file name up to the dimensioning step highlighted.
Tip!
An alternative can be created from every dimensioning step in the navigation tree. Like this
several alternatives can be created.

6.2.2 Application Tuner
In the planning phase of a machine, there generally is only one worst-case-scenario or one reference
scenario for the requirements of the machine. However, these scenarios are not able to include all
operating statuses of the machine. Often, further requirements must be checked:
• Is the drive able to move an even greater mass?
• Is the drive able to accelerate even faster?
• Is there a need for considering an emergency stop with a short braking time?
• What is the utilisation or energy balance in the partial load operational range?
• What is the impact of different recipes on the drive?
Features of the Application Tuner:
• Change the data of the application and the motion data as well as to observe and optimise the
impacts on the drive if need be.
• integrate further possible operating statuses and material recipes into the dimensioning for the
reference scenario.
• Create the optimised drive solution as individual DSD project.
• Output a protocol of the optimised drive solution.
• Support of the additional checks required for emergency stop scenarios for winding drives.

6.3 Dimensioning "easily and quickly" or "complex and precisely"
According to the application, the dimensioning process in the DSD can be clearly simplified.
• For an application, always enter the data of the application and describe the motion.
• Calculated utilisation values, diagrams, and options can be output.
For the quick and roughly estimated dimensioning several possibilities are provided. Like this, the
number of parameters can be reduced, the motion profile presented in a simplified manner, or the
product options can be left out. By this the amount of processing is considerably reduced for simple
dimensioning processes.
If an application is to be optimised, and if dynamic processes play an important role, this can be taken into consideration by accordingly extending the dimensioning. In order to present the products
in a thorough manner, the options required can also be specified.
In the Input area you carry out the actual entries for the drive dimensioning via the text and list
fields:

ues

6.3.1 Roughly estimated calculation
For a roughly estimated determination of the requirements you can alternatively dimension a controlled drive with a predefined motion profile according to operating mode.
• The operating modes are scaled loads (VDE 0530) for a drive motor. The operating modes
S1 ... S10 are distinguished.

6.3.2 Product features
Apart from the component data required for physical dimensioning, there are also important characteristics for mounting, extension, and operation. After dimensioning the drive system you can individually define the characteristics for each component via the Product features dimensioning step.
• For dimensioning a component, product features are not required.
• The dimensioning process can be completed without defining the product features.
• Alternatively you can define the options in the Drive Solution Catalogue (DSC).

6.4 Cost optimisation factors
Of course, costs are directly associated with the service factors and service durations of the individual drive components.
• Overdimensionings can render a drive system unattractive very quickly.
• Underdimensionings may make the drive system seem attractive at first. However, high followup costs and damage to the company's image can occur if the drive does not perform the tasks
required.
Tip!
When carrying out dimensionings, always follow the principle "Not more and not less than
required!"
Here the user has to make the best decisions with the help of the wizard in the DSD.
• For this purpose, the following table specifies important decision parameters with regard to
costs:

7.2 Basic calculations
In this chapter the basic calculations required for ascertaining the requirement of the application
are described. The initial situation results from the calculations which have to be carried out for the
respective application (e. g. travelling drive).
The requirement of the application results from
• The torque required,
• The speed required,
• The power resulting from the two.
7.2.1 Torque
To dimension the drive system correctly, the torque of the application is required. It should be calculated completely for the application, taking the losses (e. g. friction) into consideration. A division
into a dynamic and a stationary component cannot be effected, as the friction partly has an effect
on dynamic components, and to some extent it has not.
For instance, in the case of a spindle, due to the linearly moved masses losses are created with regard to the dynamic forces, and due to the moment of inertia of the spindle the dynamic torques act
on the drive system without losses. Furthermore the losses depend on different factors depending
on the application. It is therefore assumed that the required torque of the application M
is given:
app
[7-1] Equation 1: Total torque of the application
Tip!
The equation for calculating the torque can be found in the chapter for the respective application model.
Basically the total requirement of the torque results from the following.
• The dynamic torque of the application results from the multiplication of the moment of inertia
and the angular acceleration:
[7-2] Equation 2: Dynamic torque of the application
• The stationary torque M
is calculated on the basis of the application-specific equations that
sds
are listed in the chapter for the respective application model.
• The total torque of the application results from adding the dynamic and the stationary component:

7.2.3 Motion of the application
For the calculations, the motion must be taken into consideration. A distinction is made between
the predefined and the user-definable motion profile.
• User-definable motion profile:
• The motion profile is based on the standardised S8 … S10 operating modes according to
VDE 0530.
• For calculating the motion profile the parameters at each time have to be calculated.
• The maximum values for power, torque, and speed are important reference values for the calculation of the motion profile.
• The motion profile can be created graphically, defined based on numerical values or be imported.
• Predefined motion profile:
• The motion profile is based on the standardised S1 … S7 operating modes according to
VDE 0530.
• For the calculation, apart from the stationary status also dynamic processes are taken into
consideration.
• The predefined motion profile provides a simple possibility of entering a motion profile with
acceleration, constant travel, deceleration, and standstill.
• The settings "Brake at standstill" and "Controller inhibit at standstill" can be selected.
• The parameters "Delay time", "Starting time", "Cycle time", and "Direction of movement" can
be altered.

7.3 Belt drive, rotating
The vast majority of positioning systems require linear movements. If a rotating drive is used, the
rotation of the motor has to be converted into a linear movement. The speeds that can be achieved,
and therefore the dynamics of the positioning process and the repeat accuracy, and thus the quality
of the positioning process to a great extent are defined by the mechanics.
Characteristics of a rotating belt drive
• A motor actuates a belt pulley which in turn actuates a toothed belt. The mass to be moved,
which usually consists of a tool and the payload, is fastened to the toothed belt.
• Toothed belts allow for a higher speed, but a lower positioning accuracy of approx. 0.1 mm. The
positioning path is greater than that for the spindle, but it also is limited.
• Toothed belt drives are very often used in applications for material handling , since they offer a
high speed and an accuracy sufficient for this application.
Requirements with regard to a drive system for positioning
• High dynamic performance to achieve short positioning times
• High accuracy, according to the application
• High degree of reliability

7.3.1 Applications with a horizontal direction of movement
• Application of a rotating belt drive with wheel guide:
• Application of a rotating belt drive with linear guide:
Note!
The losses have a relatively high constant proportion, i. e. the torque loss is almost irrespective of the load torque. The reason for this is the pretension of the belt, which is required if dynamic traversing with a high precision is to be carried out.
The DSD thus considers the efficiency to be entered as a constant torque. For the calculation always an efficiency at the highest load is assumed. Because of this definite dimensioning, no additional constant torque has to be specified.

• The movement is carried out within one of the three dimensional axes (horizontally x, y, and
vertically z), or within a plane inclined to the horizontal by the angle β (0 ... 90°).
• For Z axes often an omega arrangement of the belt is selected, because less operating space is
required.

Consideration of the radial and axial forces on the bearings in the gearbox and motor
In addition to the torques to be transmitted, considering the radial and axial forces on the rotor is
also important for the selection of the gearbox and motor.
Note!

Axial forces occur if the belt pulley is not in alignment. Avoid a belt pulley that is not in

7.4 Omega belt drive
The vast majority of positioning systems require linear movements. If a rotating drive is used, the
rotation of the motor has to be converted into a linear movement. The speeds that can be achieved,
and therefore the dynamics of the positioning process and the repeat accuracy, and thus the quality
of the positioning process to a great extent are defined by the mechanics.
Characteristics of an omega belt drive
• A motor actuates a belt pulley which in turn actuates a belt or a toothed belt. The mass to be
moved, which usually consists of the drive, a tool, and the payload, is fastened to the toothed
belt.
• Toothed belts allow for a higher speed, but a lower positioning accuracy of approx. 0.1 mm. The
positioning path is greater than that for the spindle, but it also is limited.
• Belt drives are very often used in applications for material handling , since they offer a high
speed and an accuracy sufficient for this application.
Requirements with regard to a drive system for positioning
• High dynamic performance to achieve short positioning times,
• High accuracy, according to the application
• High degree of reliability

7.4.1 Applications with a horizontal direction of movement
• Application of an omega belt drive with wheel guide:
• Application of an omega belt drive with linear guide:
Note!
The losses have a relatively high constant proportion, i. e. the torque loss is almost irrespective of the load torque. The reason for this is the pretension of the belt, which is required if dynamic traversing with a high precision is to be carried out.
The application model thus considers the efficiency to be entered as a constant torque.
For the calculation always an efficiency at the highest load is assumed. Because of this
definite dimensioning, no additional constant torque has to be specified.

• The positioning process can be carried out via time-controlled path generators (positioning software) or via path-controlled path generators (electronic cams).
• The movement is carried out within one of the three dimensional axes (horizontally x, y, and
vertically z), or within a plane inclined to the horizontal by the angle β (0 ... 90°).

The torque loss depends on the torque MD which is to be transmitted, so that the resulting torque
defining the power of the application is calculated via the following equation.

considered during this calculation.
• The equation is suitable to calculate different operating points for an application with a predefined motion profile (S1, S2, S3, S6).

Consideration of radial forces
Depending on the bearing, radial forces may occur in a rack drive which act on the gear shaft at the
output end of the gearbox. DSD does not check whether the radial forces exceed limit values. This
must be checked manually. The radial forces must be considered in the drive dimensioning.
Consideration of axial forces
In the case of racks and pinions with helical bearings, axial forces occur which act on the shaft bearings at the output end of the gearbox or at the motor. DSD does not check whether the axial forces
exceed limit values. This must be checked manually. The axial forces must be considered in the drive
dimensioning.
Required torque of the application
During the calculation of the required torque of the application additional moments of inertia, like
for example that of the pinion or of additional shafts, are also taken into consideration.

7.6 Spindle drive
The vast majority of positioning systems require linear movements. If a rotating drive is used, the
rotation of the motor has to be converted into a linear movement. The speeds that can be achieved,
and therefore the dynamics of the positioning process and the repeat accuracy, and thus the quality
of the positioning process to a great extent are defined by the mechanics.
Characteristics of a spindle drive
• A motor (if required with a gearbox) actuates a spindle that moves the spindle slide with the
load.
• Spindles are used for a high positioning accuracy and low speeds. The positioning path is limited.
• For the accurate adjustment of limit stops and the accurate positioning of the workpiece in production machines, spindles are generally used.
7.6.1 Calculations
For a spindle drive according to the drawing the following applies:
First the leadscrew pitch is converted to a resulting radius.
[7-51] Equation 1: Resulting radius of the spindle
The moment of inertia of the spindle can be determined if its geometry is known.
• The following, for instance, applies to a solid cylinder:
