7.21.2 Combining drive axes

7.21.2.1 Central mains supply via regenerative power supply module

[7-181] Inverter with rectifier and inverted rectifier on central mains supply via regenerative power supply module

[7-182] Single-axis and double-axis devices (e.g. i700) on central mains supply via regenerative power supply module

Excessive electrical energy (braking energy) is made available to the drive axes in the DC-bus con-

nection or is fed to the mains via the regenerative power supply module.

• The arrangement can be dimensioned in the DSD.

• The drive axes can be each dimensioned separately in the DSD.

• In the "Dimension the multi-axis system" application you combine the drive axes and dimen-

sion the regenerative power supply module.

• DSD calculates the entire power requirement. For operation in generator mode it is checked

whether the braking power needs to be dissipated via an additional brake resistor if the re-

generative power of the regenerative power supply module is not sufficient.
