Allen-Bradley powerflex 700 Reference Manual

Section 4
Selecting An External Resistor
In order to select the appropriate External Dynamic Brake Resistor for
your application, the following data must be calculated.
Peak Regenerative Power
(Expressed in watts)
This value is used to determine the maximum resistance value of the
Dynamic Brake Resistor. If this value is greater than the maximum
imposed by the peak regenerative power of the drive, the drive can trip
off due to transient DC bus overvoltage problems.
Power Rating of the Dynamic Brake Resistor
The average power dissipation of the regenerative mode must be
estimated and the power rating of the Dynamic Brake Resistor chosen to
be greater than the average regenerative power dissipation of the drive.
