Parameter Reference
Inj Braking
Parameters::Motor Control::Inj Braking
Designed for VOLTS/Hz Motor Control Mode.
The injection braking feature provides a method of stopping spinning induction motors without returning the kinetic energy of the motor and load
back in to the dc link of the Drive. This is achieved by running the motor highly inefficiently so that all the energy stored in the load is dissipated in the
motor. Thus, high inertia loads can be stopped without the need for an external dynamic braking resistor.
Parameter Name No.
