C-92 Parameter ReferenceAC30 series Variable Speed DriveInj BrakingParameters::Motor Control::Inj BrakingDesigned 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 loadback 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 themotor. Thus, high inertia loads can be stopped without the need for an external dynamic braking resistor.Parameter Name No. Path Default Range Units WritableDC Inj Deflux Time 0324 Parameters::Motor Control::Inj Braking 0.500 0.100 to 20.000 s ALWAYSMotor defluxed duration before starting injection brakingDC Inj Frequency 0325 Parameters::Motor Control::Inj Braking 9 1 to 500 Hz ALWAYSMax frequency applied to the motorDC Inj Current Limit 0326 Parameters::Motor Control::Inj Braking 100.0 50.0 to 150.0 % ALWAYSMotor current valueDC Pulse Time 0327 Parameters::Motor Control::Inj Braking 2.000 0.000 to 100.000 s ALWAYSDuration of dc pulse for motor speed below 20% of base speedFinal DC Pulse Time 0328 Parameters::Motor Control::Inj Braking 1.000 0.000 to 10.000 s ALWAYSDuration of the final dc holding pulseDC Current Level 0329 Parameters::Motor Control::Inj Braking 3.0 0.0 to 25.0 % ALWAYSLevel of dc pulse applied
