Microprocessor-Driven Performance

Cableform's proprietary microprocessor control of IGBT (Isolated-Gate-Bipolar Transistors) provides LMCTM powered mining equipment with these advantages:

  • Maximum motor torque available at all speeds
  • Smooth controlled acceleration
  • Smooth controlled braking
  • Optional Dynamic Braking
  • Adjustable Parameter setting
  • Solid-State Diagnostics
  • Motor Protection software
  • Custom Software Available


  • Linear Current Sense allow high resolution at low and high currents
    • Low HP (Low Current) motors operate the same as High HP (High Current) motors.
    • Standardization: Shield haulers, scoops, personnel carriers, etc all can use the same power section.
    • Increased control of speed and torque.
    • Smoother operation of vehicles.
  • Motor overcurrent and overvoltage protection
  • Solid-State Reversing of series-wound motors
    • Protects the system from the inductive DI/DT surge associated with reversing the armature current - it's simple, automatic, and failsafe.
    • No Forward or reverse contactors.
  • A Single contactor (Line Contactor) is all that is required
    • A Dynamic Brake contactor is required on systems utilizing dynamic braking.
