6.13 Brake/Regeneration Resistor
The AMD2000 3A and AMD2000 9A drives feature 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.
Mode
Connection
Internal Regeneration Resistor
Link pins P & D
External Regeneration Resistor
Connect resistor to P & C
Danger: Do not short circuit connector P to C. Connector P is live with active high voltage.
Please refer to sections 12.5.14 Regenerative Braking and 12.14 Brake/Regeneration Resistor for additional
information.
