    西门子G120是一种包含各种功能单元的模块化变频器系统。基本上包括:

    •控制单元 (CU)

    •电源模块 (PM)

    CU 在多种可以选择的操作模式下对 PM 和连接的电机进行控制和监视。通过控制单元,可与本地控制器以及监视设备进行通讯。电源模块的功率范围为 0.37 kW 至 250 kW。
     

    The SINAMICS G120 frequency converter is designed to provide precise and cost-effective speed/torque control of three-phase motors.

    With different device versions (frame sizes FSA to FSG) in a power range from 0.37 kW to 250 kW, it is suitable for a wide variety of drive solutions.
     

    Example: SINAMICS G120, frame sizes FSA, FSB and FSC; each with Power Module, CU240E‑2 F Control Unit and Basic Operator Panel BOP-2

    Example: SINAMICS G120, frame sizes FSD, FSE, FSF and FSG; each with Power Module, CU240E‑2 F Control Unit and Intelligent Operator Panel IOP‑2

    Operator-friendly design

    SINAMICS G120 is a modular converter system that essentially comprises two function units:

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

    The Control Unit controls and monitors the Power Module and the connected motor using several different closed-loop control types that can be selected. It supports communication with a local or central controller and monitoring devices.

    The Power Module supplies the motor in the power range 0.37 kW to 250 kW. It features state-of-the-art IGBT technology with pulse-width-modulated motor voltage and selectable pulse frequency. Comprehensive protection functions provide a high degree of protection for the Power Module and the motor.

    The Control Units can be combined with the following Power Modules:

    Safety Integrated

    SINAMICS G120 standard converters are available in different versions for safety-related applications。 The PM240‑2 and PM250 Power Modules are already designed for Safety Integrated。 A drive can be combined with a Control Unit with safety functions (see overview) in order to create a Safety Integrated drive。 The availability of Safety Integrated functions depends on the type of Control Unit。

    1) The SBC function can be utilized only if a Safe Brake Relay is installed.

    2) SSM possible only for CU240E‑2 DP‑F / CU240E‑2 PN‑F Control Units with PROFIsafe.

    3) With license for Extended Safety functions.

    Basic Safety functions (certified according to IEC 61508 SIL 2, and EN ISO 13849‑1 PL d and Category 3)

    • Safe Torque Off (STO)
      to protect against active movement of the drive
    • The PM240‑2 Power Modules, frame sizes FSD to FSG, offer additional terminals to achieve STO acc. to IEC 61508 SIL 3 and EN ISO 13489‑1 PL e and Category 3.
    • Safe Stop 1 (SS1)
      for continuous monitoring of a safe braking ramp
    • Safe Brake Control (SBC) is used to safely control a holding
      brake. When enabled, SBC is always activated at the same time as STO. The Safe Brake Relay is used for SBC.

    Extended Safety functions (certified according to IEC 61508 SIL 2 and EN ISO 13849‑1 PL d and Category 3)

    • Safely-Limited Speed (SLS)
      for protection against dangerous movements on exceeding a speed limit
    • Safe Direction (SDI)
      This function ensures that the drive can only rotate in the selected direction.
    • Safe Speed Monitor (SSM)
      This function signals if a drive operates below a specific speed/feed velocity.

    Basic Safety and Extended Safety functions can be activated via PROFIsafe or by means of the safety inputs。

    None of the safety functions require a motor encoder and they are thus cheaper and easier to implement。 Existing systems in particular can be simply updated with safety technology without the need to change the motor or mechanical system。

    The Safe Torque Off (STO) function can be used without restriction for all applications. The SS1, SLS, SSM and SDI functions are only permissible for applications where the load can never accelerate when the converter is switched off. They are therefore not permitted for applications involving pull-through loads such as hoisting gear and unwinders.

    Further information can be found in the section Safety Integrated.

    Efficient Infeed Technology

    The innovative Efficient Infeed Technology is employed in PM250 Power Modules。 This technology allows the energy produced by motors operating in generator mode connected to standard converters to be fed back into the supply system。 For control cabinets, an additional temperature rise can be avoided and the amount of space required can be reduced due to the fact that components such as braking resistors, braking choppers and line reactors can be eliminated。 Further, wiring and engineering costs are significantly reduced。 At the same time, energy consumption can be reduced and ongoing operating costs noticeably reduced。

    Innovative cooling concept and varnishing of electronic modules

    The new cooling system and varnishing of the electronic modules significantly increases the service life or useful life of the device。

    • Disposal of all heat losses via an external heat sink
    • Consequential convection cooling of the Control Unit, electronic modules are not located in the air duct
    • All cooling air from the fan is directed through the heat sink
    Energy efficiency

    Integrated technologies help when optimizing the energy usage of the plant or system referred to the particular application:

    • Energy-efficient vector control with or without sensors
    • Automatic flux reduction with V/f ECO mode
    • Integrated energy saving computer

    Further information can be found in the section Energy efficiency.

      • Plant-wide engineering
      • Easy to handle

This feedback capability provides enormous potential for savings because generated energy no longer has to be converted into heat in a braking resistor

    设计
    Application-orientated design of SINAMICS G120

    SINAMICS G120 standard converters are modular converters for standard drives. Selection of the SINAMICS G120 is reduced to two or three steps thanks to the modular system used.

    Selecting the Control Unit

    The optimum Control Unit is selected first, based on the number of I/Os and any additional functions required such as Safety Integrated or HVAC。 The communication options are already integrated and do not have to be additionally ordered or plugged in。 Three product series are available corresponding to the particular application。

    CU230P‑2 Control Units

    The CU230P‑2 Control Units have been specifically designed for pump, fan and compressor applications.

    Control Unit CU240E‑2

    The CU240E‑2 Control Unit is suitable for a wide range of applications in general machine construction, such as conveyor belts, mixers and extruders。

    CU250S‑2 Control Units

    The CU250S‑2 Control Units are suitable for applications involving single drives with exacting speed control requirements such as extruders and centrifuges, and for positioning tasks such as conveyor belts, lifting/lowering devices, etc. They can also be used to implement multi-motor drives without DC coupling such as wire-drawing machines and simple material lines.
