WEG - SSE05 Series Soft-Starter - Wednesday, 20 February 2019

WEG soft starters are fitted with micro processors. They are high-tech and designed to ensure the highest performance during starts and stops of induction motors. Soft-Starters are electronic starters designed to accelerate, decelerate and protect three-phase induction motors, controlling the voltage applied on the motor. The SSW05 Plus Micro Soft-Starters, with DSP control (Digital Signal Processor) have been designed to ensure excellent performance during starts and stops of induction motors.

Soft-Starters are electronic starters designed to accelerate, decelerate and protect three-phase induction motors, controlling the voltage applied on the motor. The SSW05 Plus Micro Soft-Starters, with DSP control (Digital Signal Processor) have been designed to provide excellent performance during starting and stopping of electric motors with superb cost/benefit ratio.

The operator interface allows easy parameter setting, simplifying the start-up and operation activities. The SSW05 Plus Micro Soft-Starters are compact, optimising the space in electrical panels and incorporated all protections for the driven motor.

Convenience in Motor Start and Protection

SSW05 soft-starters are static starters designed for motor acceleration, deceleration and protection. The control of the voltage applied to the motor, by adjusting the firing angle of the thyristors, provides smooth starts and stops. By properly setting the variables, the obtained torque is adjusted to the load requirement, ensuring the minimum necessary starting current.

The SSW05, featuring DSP control (Digital Signal Processor) is designed for optimal performance in motor start and stop, with excellent cost effectiveness. They incorporate all the protections for your electric motor, in addition to being easily set, simplifying the start-up activities and daily operations. Their compact dimensions contribute to the optimisation of spaces in electrical panels.

Applications

  • Rotary vane vacuum pump
  • Centrifugal pumps
  • Calenders (starts with no load)
  • Screw compressors (start in relief)
  • Mixers
  • Cellulose refiners
  • Axial fans (low inertia - light load)

Main Characteristics

  • Currents: 3 to 85 A
  • Voltage: 220 to 575 V
  • Control with DSP
  • Remote HMI (optional)
  • Built-in motor protections
  • Built-in RS-485 serial communication

Benefits

  • Built-in bypass
  • Control with digital processor (DSP)
  • High efficiency
  • Compact
  • It extends the lifespan of the motor and mechanical devices of the driven machine by eliminating mechanical shocks
  • Easy to operate, adjust and service
  • Simple electrical installation
  • Operation in environments up to 55 °C
  • Great reduction of the stresses on the couplings and driving devices (gear boxes, pulleys, gears, belts) during the start

 Remote Operating Interface

It is an operating interface for installation on panel door or machine console. This interface also incorporates the copy function, which allows you to copy the parameter settings from one SSW05 to another in a quick and reliable way, saving programming time in machine manufacturing applications.

SuperDrive Programming Software

Programming software via personal computer in Windows environments for parameter setting, command and monitoring of the SSW05 Plus. It allows you to edit parameters on-line and parameter files stored on the microcomputer off-line.

It is possible to store parameter files of all the SSW05 Plus units present in the application. The SuperDrive also includes functions to transfer the parameter set from the personal computer to the SSW05 Plus and vice versa. The communication between the soft-starter and personal computer is done via RS232 seriall interface.
