Drives for conveyors in mining | Danfoss

For downhill conveyors, continuous regenerative braking operation is typically required. Here, an Active Front End (AFE) drive or alternatively a regenerative drive panel solution, using a standard 6pulse drive with separate regenerative module, is the best solution to feed back energy when the conveyor runs downhill.

If the measured speed becomes lower (conveyor retardation slows down) a signal is transmitted to operate the solenoid valve towards its closed position until the speed corresponds to the programmed ramp down. This increases the back pressure on the brakes and decreases the braking torque. Alternatively, if the
