4.2.2 Busbar system for the DC bus

The DC busbar system of the i700 device series is dimensioned for 100 A effective current

(RMS). It responds to the arising thermal load with a time constant of approximately 5

minutes.

Using an upstream mains choke or mains filter (integrated mains choke) reduces the

harmonic content of the mains current and the DC bus current. Hence, the permissible

supply power P

is increased at 100 A RMS.

Permissible supply power P

(via the DC busbar system)

Mains voltage

400 V 480 V

i700 power supply module with mains choke/filter £ 51 kW £ 62 kW

i700 power supply module without mains choke/filter £ 34 kW £ 41 kW

The required supply power P

consists of the sum of the power requirement of the single

controllers (see also from page 113).

In many cases, the rated power of the controllers P

and their power losses P

can be added

and be compared with the permissible P

The actual supply power P

(mean value via 3 min) can be detected by using familiar travel

profiles of the controllers and can be compared with the permissible P

 Tip!

The limits of the system only have to be considered in a few applications.

If the compliance cannot be ensure with a simple test, the test can be carried

out using the «Drive Solution Designer» PC software.

«DSD» completely maps the required tests for multi−axis systems. This

provides for a simple dimensioning of the network. Moreover, an

energy−optimised dimensioning of a multi−axis system is possible.

If you do not use «DSD» yet, refer to your Lenze contact.
