New Inverter Drive provides precise and cost-effective speed/torque control of AC motors.

 

 

The new Siemens SINAMICS G120 series of frequency converters is designed to provide precise and cost-effective speed/torque control of AC motors.  With different device versions (frame sizes FSA to FSF) in an output range of 0.37 kW to 90 kW, it is suitable for a wide variety of drive solutions.  SINAMICS G120 is a modular converter system comprising a variety of functional units. The two main units are:

  • the Control Unit (CU) and
  • the Power Module (PM)

The Control Unit controls and monitors the Power Module and the connected motor in several different modes. It supports communication with a local or central controller and with monitoring equipment or input/output terminals for a direct control function.

The Power Module supplies the motor in the power range 0.37 kW to 90 kW. The Power Module is controlled by a microprocessor in the Control Unit. State-of-the-art IGBT technology with pulse-width-modulated motor voltage and selectable pulse frequency is applied to achieve extremely reliable, flexible motor operation. An extensive range of protective functions afford a high degree of motor protection.

Furthermore, a large number of additional components are available, such as:

  • Basic Operator Panel (BOP) for basic programming and copying of drive parameters
  • Line filter, classes A and B
  • Line reactors
  • Braking resistors
  • Output reactors for long motor cables
