The Drive Solution Designer (DSD) PC software helps you to dimension your drive network.

For expert advice, you may also contact your Lenze sales representative when

dimensioning your application.

Time/performance diagram

For determining the performance of your drive network, create a time/performance

diagram for all axes for a complete machine cycle. The power requirements of the drive

network are calculated by adding the individual performances occurring at the same time.

Positive results show the AC requirements for the dimensioning of the power supply units.

Negative results show the brake power to be dissipated via brake choppers at the brake

resistor.
