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.
