SINAMICS G120

The SINAMICS G120 family of closed-loop vector drives offers high levels of integrated safety, energy savings, and network connectivity. Available in three voltage variants for connection to 200, 400 and 690V with power ratings from ½ to 400 Hp (0.37 to 250 kW), this modular and scalable standard drive may be configured in a wide variety of designs to meet a vast array of industrial drive applications. In addition, built-in math and logic eliminate the need for a separate PLC. The EN 60204 safety functions of the SINAMICS G120 are fully integrated into the drive and include Safe Torque Off, Safe Stop 1, Safety Limited Speed and Safe Brake Control. As a result, production plants obtain greater levels of safety while requiring less overhead to integrate the drives into fail-safe, automation, and drive environments. The SINAMICS G120 vector drive also complies with NFPA 79-2007

The Control Unit controls and monitors the Power Module and the connected motor using multiple selectable closed-loop control types. It supports communication with a local or central controller and monitoring devices. The Power Module supplies the motor in a power range from 0.5 to 400 Hp (0.37 to 250 kW.) It features state-of-the-art IGBT technology with pulse width modulation for extremely reliable and flexible motor operation. Comprehensive protection functions provide a high level of protection for the power module and the motor.

Siemens offers a wide range of Power Modules for the most diverse drive requirements.

Using the latest power component technology, the PM240-2 Power Modules offer many benefits not seen before in general purpose variable frequency drives (VFDs). With higher power densities, matching control units and operator panels, enhanced vector control, basic positioning capabilities, the new G120 proves to be a best-in-class VFD.

 

The industry-leading power module for standard applications in mechanical engineering. PM240-2 includes a braking chopper (four-quadrant applications) and is suitable for a large number of applications in general mechanical engineering. 

 

Power module PM240-2 is available for the following voltage and power ranges:

  • 1 AC 200 – 240V:         0.5 – 5 Hp (0.55 – 4.0 kW)
  • 3 AC 200 – 240V:         7 – 75 Hp (5.5 – 55 kW)
  • 1/3 AC 380 – 480V:     0.5 – 350 Hp (0.55 – 250 kW)
  • 1/3 AC 500 – 690V:     15 – 350 Hp (11 – 250 kW)

The push-through configuration includes the same features as the built-in versions, but dissipate the majority of the heat loss outside the control cabinet. The modules come in six frame sizes FSA - FSF and are available for the following voltage and power ranges:

  • 3 AC 200 - 240V:     1, 3, 5, 25, 40, 75 Hp (0.75, 2.2, 4, 18.5, 30, 55 kW)
  • 3 AC 380 - 480V:     4, 10, 20, 50, 75, 175 Hp (3, 7.5, 15, 37, 55, 132 kW)

The ideal power module for requirements with regenerative power feedback. This means that any braking energy is directly fed back into the supply system (four-quadrant applications – a braking chopper is not required).

 

The PM250 power module is available for the following voltage and power ranges:

  • 3AC 380 – 480V ±10%:  10 – 125 Hp (7.5 – 90 kW)

The Control Unit (CU)
 controls and monitors the power module and the connected motor in several selectable operating modes. It supports communications to a local control as well as to monitoring devices and equipment networks ensure exceptional drive performance that may be integrated to the field level. In addition to control functions, the CU can also perform other tasks which can be adapted to the relevant application by parameterization. Siemens has designed several CUs for the SINAMICS G120 focusing on various applications.

Including expanded I/O quantity structure, this is ideal for encoderless applications with safety requirements.

This unit is specially suitable for drives with high speed and torque accuracy requirements. The I/O interface, the fieldbus interfaces, and the additional software functions are perfect for these applications.

The unit's I/O interface, fieldbus interfaces, and additional software functions make it especially suitable for drives with integrated technology functions for pump, fan and compressor applications. 

With SINAMICS accessories, you further increase the operation and control capabilities of SINAMICS G120.
