Too strong a load to decelerate or brake for the drive
For applications generating movement, the inertia of a load to be decelerated or braked may be too high:
The engine will then behave like an asynchronous generator . Which means the load will be reflected directly on the DC bus capacitors of the drive .
However, the variable speed drive has a storage capacity . Once this limit is exceeded, the load can cause degradation or even destruction of the drive and its surroundings.
The braking resistor allows the correct operation of the drive
When braking partially or completely, the braking resistor will allow:
- the transformation of electrical energy into heat energy
- to absorb strong power surges over long cycles
- to preserve your equipment
