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.
