N300 INSTRUCTION MANUAL

BRD (dynamic braking) function

This function only operates with the N300-11kW and lower, as they have
the built-in BRD.
This function is to consume regenerative energy from the motor as heat by
the use of an external resistor.
Regeneration occurs when the motor is decelerated to quickly and the motor turns into a generator and voltage
flows back into the inverter.
To use the BRD function, set following condition.
