KIMO Soft start, soft stop and braking unit: LEKTROMIK DS1


Digital soft starter / Braking unit

Features Applications
  • Microprocessor controlled
    • One-button operation
    • 2-line display
  • Optional interfaces (e.g. Ethernet, Profinet)
  • 3 operating modes:
    • Soft start – soft stop
    • Soft start – braking
    • Soft start – soft stop in delta connection
  • Ramp-up and ramp-down times separately adjustable
  • Suitable for IE1, IE2 and IE3 motors
  • Three-phase controlled soft start / soft stop
  • Start with current limitation
  • Integrated bypass relay to minimize losses
  • Phase failure and rotating field monitoring
  • Integrated DC brake: fully controlled, 2-phase
  • Integrated stillstand detection
  • Integrated evaluation of the motor winding temperature
  • Predefined parameter sets for different applications
  • 2 memories for user parameter sets
  • Woodworking machines (saws, planing benches, grinding machines)
  • Machines with gear, belt and chain drives
  • Conveyors, fans, compressors and pumps
  • Braking of machines with long stopping times


    Soft start, soft stop and braking of squirrel cage motors
    2,2 – 90 kW

    Features Applications
    • Electronic DC injection brake with a short delay time can be integrated in controller
    • Compact unit easily retrofitted
    • Shutdown on detection of phase failure during ramp up
    • Controller inhibited when phase sequence is incorrect(E2, E4)
    • Version for operation with two phase sequences forreversing drives available (E22, E42)
    • Auxiliary module (OPTION I1) allows:
      • Soft start with current limit
      • Switch-on torque pulse
      • Monitoring of power with overload trip
      • Improvement of power factor at low load
    • Machines with gearbox, belt or chain drives
    • Drives using pole-change motors
    • Conveyor belts (also high speed and high load transportation systems)
    • Machines with high moments of inertia e.g. mills, compactors, centrifuges
    • Grinding machines and circular saws
    • Packing equipment
    • Fans and compressors
    • Pumps, in particular to reduce hydraulic shock waves
