Brake Resistor
Dynamic braking (DB) helps bring the motor to a smooth and rapid stop when working with high
inertia loads. As the drive lowers the frequency of a motor with high inertia connected,
regeneration occurs. This can cause an overvoltage situation when the regenerative energy flows
back into the DC bus capacitors. A brake resistor prevents these overvoltage faults.
AxN 09.20.4 Drive has an internal brake resistor inside the drive. And it can also connect an external
brake resistor (Recommended).
WARNING: Do not operate AxN Drive without any brake resistor. Failure to comply may result in
damage to braking circuit or drive.
Internal Brake Resistor
Specifications
Every AxN 09.20.4 Drive has an internal brake resistor. Regard to its properties, using internal
brake resistor in real applications is
NOT
recommended. Refer to the following table for more
