About Lenze
The 5 phases
Lenze makes many things easy for you.
With our movated and commied approach, we work together with you to create the best
possible soluon and set your ideas in moon - whether you are looking to opmise an exist-
ing machine or develop a new one. We always strive to make things easy and seek perfecon
therein. This is anchored in our thinking, in our services and in every detail of our products.
It's as easy as that!
1 Developing ideas
Are you looking to build the best machine possible and already have some inial ideas? Then
get these down on paper together with us, starng with small innovave details and stretch-
ing all the way to completely new machines. Working together, we will develop an intelligent
and sustainable concept that is perfectly aligned with your specic requirements.
2 Draing concepts
We see welcome challenges in your machine tasks, supporng you with our comprehensive
experse and providing valuable impetus for your innovaons. We take a holisc view of the
individual moon and control funcons here and draw up consistent, end-to-end drive and
automaon soluons for you - keeping everything as easy as possible and as extensive as nec-
essary.
3 Implemenng soluons
Our easy formula for sased customers is to establish an acve partnership with fast decision
making processes and an individually tailored oer. We have been using this principle to meet
the ever more specialised customer requirements in the eld of machine engineering for
many years.
4 Manufacturing machines
Funconal diversity in perfect harmony: as one of the few full-range providers in the market,
we can provide you with precisely those products that you actually need for any machine task
— no more and no less. Our L-force product porolio a consistent plaorm for implemenng
drive and automaon tasks, is invaluable in this regard
5 Ensuring producvity
Producvity, reliability and new performance peaks on a daily basis these are our key success
factors for your machine. Aer delivery, we oer you cleverly devised service concepts to
ensure connued safe operaon. The primary focus here is on technical support, based on the
excellent applicaon experse of our highly-skilled and knowledgeable aer-sales team.

Dimensioning
3 methods for dimensioning
Fast: Selecon of the inverter based on the motor data of a 4-pole asynchronous motor.
Detailed: In order to opmise the selecon of the inverter and all drive components, it is
worth to execute the detailed system dimensioning based on the physical requirements of the
applicaon. For this purpose, Lenze provides the «Drive Soluon Designer» (DSD) design pro-
gram.
Manual: The following chapter guides you step by step to the selecon of a drive system.
