Project planning example for checking the total resistance

The following example shows the check necessary for the maximum permissible total resistance with a required motor overload of 250% and a 400 V supply system.

The following components/devices are taken into account:

• Supply cables
• Conductor rails
• Transformer
• 5 MDR91B-0750-.. supply and regenerative modules

• Customer data
• Consideration of the furthermost regenerative module
• Calculation
