Regeneration Resistor
The D2xxx drives have an inbuilt regeneration resistor. Regeneration refers to the process whereby when the
motor is actively providing energy to the drive and then stops, the kinetic energy in the entire mechanical system
connected to the shaft of the motor gets transferred to the bus capacitance in the drive, which increases the
voltage. This happens because of the motor inductance. When the voltage on the bus capacitance exceeds
385V the drive will connect the internal regeneration resistor in addition to any external regeneration resistor that
is provided by the user. The internal resistor is only capable of dissipating a power of 40W for the D2103 and
60W for the D2015 and D2109. In addition to the power rating of the resistor to be observed the instantaneous
energy maximum for each resistor must also be observed. This is 24.7 joules for the D2103 drive and 143 joules
for the D2015 and D2109. If there is more regeneration power than this is created then the user must connect an
external resistor.
In addition to the energy limitation and average power limitation of the regeneration resistors, the rate of
deceleration should not result in a DC Bus Overvoltage trip. This can occur if the instantaneous regenerated
power exceeds the power being dissipated by the regeneration resistor. This is rarely an issue but can be a
problem where very rapid decelerations at high retarding torques are desired.
this is a concern.

Regeneration Resistor Selection, Regeneration Energy and Power
The starting points for the calculations regarding the required regeneration resistor are the two equations for
kinetic energy in the system, and are dependent entirely on the application of the user.
