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.
