Peak braking power

The maximum peak braking power that can be achieved is specified by the resistance value and the DC link voltage. It is calculated as follows:

Pmax

Maximum peak braking power that the braking resistor can absorb

UDCL_max

Maximum DC link voltage:

  • 650 V for 230 V units
  • 980 V for 400 V units

CW

Braking resistance value

The maximum peak braking power required by the application is calculated from the regenerative parts within a cycle.

The peak braking power required by the application must be lower than the maximum peak braking power that can be achieved and absorbed by the braking resistor.

The peak braking power for each braking resistor is specified in the chapter Braking resistors.
