Parameter Reference
Braking
Parameters::Motor Control::Braking
The braking function controls the rate at which energy from a regenerating motor is dumped into a resistive load. This dumping prevents the dc link
voltage reaching levels which would cause an Overvoltage trip.
Parameter Name No.
Braking Enable 0249
Enables operation of the dynamic braking feature.
Brake Resistance 0251
The value of the dynamic braking load resistance.
Brake Rated Power 0252
The power that the load resistance may continually dissipate.
Brake Overrating 0253
Multiplier that may be applied to Brake Power for power overloads lasting no more than 1 second.
0254
Braking Active
A read-only parameter indicating the state of the brake switch.
Functional Description
When enabled, the Braking feature monitors the internal dc link voltage every millisecond and sets the state of the brake switch accordingly. When
using braking, the brake resistor information must be entered it ordered for the resistor protection to operate.
The Braking feature operates even when the motor output is not enabled. This allows the function to continually monitor the energy dumped into the
braking resistor, and the energy dissipated across the brake switch. With this information the Drive is able to deduce the loading on the brake
resistor.
