7.21.2.2 Central mains supply via power supply module
[7-186] Central mains supply via power supply module
Excessive electrical energy (braking energy) is made available to the drive axes in the DC-bus con-
nection.
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 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.
