RAKE CHOPPER
Note: An internal brake chopper is installed in three phase supply MI2 and MI3
size drives
0 = No brake chopper used
1 = Brake chopper used in Run state
2 = Used in Run and Stop state
When the inverter is decelerating the motor, the energy stored to the inertia of
the motor and the load are fed into an external brake resistor, if the brake
chopper has been activated. This enables the inverter to decelerate the load
with a torque equal to that of acceleration (provided that the correct brake re-
sistor has been selected). See separate Brake resistor installation manual.
