Programmable Mining Control
In combination with HBT Controlled Start Transmission (CST) drives, the PMC-D controller offers control of AFC drives with unparalleled integration of overall system control. Typically dedicated to a gearbox or drive and mounted close to it, the PMC-D contains all the necessary hardware and tried-and-tested CST control algorithms to control a drive system effectively.
The intrinsically safe PMC-D control is used on shearer or plow faces to provide high level AFC (armed face conveyor) and plow automation. Each Drive unit needs to be equipped with one PMC-D control unit and equivalent I/O to operate the CST drives or UEL gearbox functions.
In such a system a PMC-V provides the Human Machine Interface (HMI) to interfere with the PMC-D controls to operate manual mode, visualize and change parameters and show actual process values. Within a PMC-D system minimum one and typically up to 3 PMC-Vs are in equal operation.
The PMC-D system can control extremely sensitive the speed and torque of highly powered AFC CST drive. Using Profibus network all PMC-Ds and PMC-Vs in a system could exchange process data over long distances with high frequency.
