A regenerative common DC bus drive system multidrive can be used to control the operation of the downhill conveyor and any other machines or conveyors in the process see B1. Here the drive’s inverter units one inverter unit per one motor are connected to the multidrive’s common DC bus. The two downhill conveyor motors are mechanically

It also provides an option of rollback control for the uni-direction conveyor and most importantly for uphilldownhill regenerative conveyors the opening of braking can also be controlled in a gradual programmable way. Latter is done by continuously monitoring the conveyor s speed by means of encoder and controlling the braking ramp action.
Jun 12 2003 I want to use regenerative braking continually 24hrs a day for the first 6 months as the weight of the load will drive the conveyor down. Speed control isn't critical as the whole system will be working at one speed but I want to control the speed of the luffing conveyor to match the other conveyors
Regenerative Vfd Control Conveyors Variable-frequency drive - Wikipedia the free encyclopedia The VFD controller is a solid-state power electronics conversion system .... torque can be in any direction such as in hoists elevators and hilly conveyors.
The main system speed reference input is only fed to conveyor A’s VFD. Conveyors A B C and D’s VFDs then feed the speed control signal upstream in cascaded conveyors—that is A → B → C ...
The value determined is the input for a complex mathematical model called virtual conveyor integrated in the control system. It is there that the reference values are calculated for all downstream conveyors and transmitted via Ethernet optical-fibre connections to local controllers and from there to the frequency converters.
There was no load sharing control issues however the conveyor was included in the overall control system re-design in order to standardize with the other conveyor drive control philosophy on conveyors CV and CV-003. Conveyor CV-002B is a combined inclinedecline conveyor 2781 m in length with an overall fall of 72 m but with a 77 m
Using indirect control the conveyor is simply operated at the optimum speed that has been previously determined for a given process recipe. Many applications require some degree of system control to provide coordination between the drive and the process. Many drives have built-in standard features or optional functions that allow the stand ...
Variable-speed drives for belt conveyor systems Nov 2000 3 ABB Process Industries - Open Pit Mining amp; Materials Handling CottbusGermany Quality criteria Introducing speed control for belt conveyors the customer has defined precise economic and technological objectives: • power savings through a load-dependent control of the belt speed
VFD as mechanical and electrical soft start The way in which a VFD controls torque makes it the best possible mechanical ‘soft’ start method. A VFD controls the electrical quanti- ties of voltage and frequency. The control is such that it enables a high starting torque to be developed for a very low starting current compared to direct to line.
