Example: SINAMICS G120, frame size FSGX; with Power Module, CU240E‑2 F Control Unit and Basic Operator Panel BOP-2

Operator-friendly design

SINAMICS G120 is a modular inverter 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 (0.5 hp to 400 hp). 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 inverters are available in different versions for safety-related applications. The PM240‑2 and PM250 Power Modules are already designed for Safety Integrated. PM240 Power Modules, frame size FSGX (i.e. 160 kW/250 hp and higher) are approved only for the Basic Safety functions (STO, SS1, and SBC). 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 FSF additionally offer 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 Monitoring (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 inverter is switched off. They are therefore not permitted for applications involving pull-through loads such as hoisting gear and unwinders.

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 inverters 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.

Additional information is provided in chapter Highlights, section Efficient Infeed Technology.

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 U/f ECO mode
• Integrated energy saving computer

Additional information is provided in chapter Highlights, section Energy efficiency.

Application-orientated design of SINAMICS G120

SINAMICS G120 standard inverters are modular inverters 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.
The CU230P‑2 is the Control Unit for the pump, fan and compressor inverters SINAMICS G120P and SINAMICS G120P Cabinet. Detailed information can be found in Catalog D 35.

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.

¹⁾ SSM is possible only with PROFIsafe.

Optional memory card with firmware V4.7 SP6 for CU230P‑2, CU240E‑2 and CU250S‑2 Control Units

Optional memory cards with licenses for CU250S‑2 Control Units only

Optional memory cards with firmware V4.6 or V4.7 for existing installations when service is required

For an overview and more information on all available firmware versions, seehttps://support.industry.siemens.com/cs/document/67364620

Selecting the Power Module

The optimum power unit can be quickly selected based on the required motor power, the supply voltage and the braking cycles to be expected. Power Modules in degree of protection IP20 are intended for installation in a control cabinet.

PM240‑2 and PM240 Power Modules – IP20 degree of protection

PM240‑2 Power Modules have an integrated braking chopper (four-quadrant applications) and are suitable for a large number of applications in general machinery construction. The same applies for PM240 Power Modules, but the PM240 Power Modules in frame size FSGX do not have an integrated braking chopper. A plug-in Braking Module is optionally available for this purpose.

PM250 Power Modules – degree of protection IP20

PM250 Power Modules are suitable for the same applications as the PM240‑2/PM240. Any braking energy is directly fed back into the line supply (four-quadrant applications – a braking resistor is not required).

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

PM240, PM240‑2 and PM250 Power Modules

¹⁾ Rated power based on the rated output current I_rated. The rated output current I_rated is based on the duty cycle for low overload (LO). Low overload (LO) generally applies for applications with low dynamic response (continuous operation), quadratic torque characteristic with low break loose torque and low speed accuracy. Examples: Centrifugal pumps, radial/axial fans, rotary piston fans, radial compressors, vacuum pumps, chain conveyors, agitators. High Overload (HO) generally applies for applications with increased dynamic response (cyclic operation) and constant torque characteristics with high break loose torque. Examples: Gear pumps, eccentric worm pumps, mills, mixers, crushers, lifting/lowering gear, centrifuges.

²⁾ The rated output current I_rated is based on the duty cycle for low overload (LO). These current values are applicable for 200 V, 400 V or 690 V.

³⁾ 160 kW ... 250 kW, PM240 Power Modules (frame size FSGX).

⁴⁾ The PM240‑2 Power Module with Article No. 6SL3210-1PE11-8. L1 corresponds to 0.37 kW (0.5 hp) with duty cycle HO.

Data based on a duty cycle with low overload (LO). Data based on duty cycle with high overload (HO), see section Power Modules.

Door mounting kit for IOP/BOP‑2

Using the optionally available door mounting kit, the IOP/BOP‑2 can be mounted in a control cabinet door with just a few manual operations (IP54/UL Type 12 degree of protection is achieved).

Push-through mounting frame for Push Through variants of the PM240‑2 Power Modules

It is advisable to use an optionally available mounting frame to install the push-through unit in a control cabinet. This mounting frame includes the necessary seals and frame to ensure compliance with degree of protection IP54. If the Power Module is installed without use of the optional mounting frame, the user is responsible for ensuring that the requisite degree of protection is provided. The kit contains all the necessary nuts and seals.

Memory card

The parameter settings for an inverter can be stored on the SINAMICS SD memory card. When service is required, e.g. after the inverter has been replaced, the drive system is immediay ready for use again. The memory card can also be used to upgrade the firmware of the Control Unit.

Brake Relay

The Brake Relay allows the Power Module to be connected to an electromechanical motor brake. This allows the motor brake to be controlled directly from the Control Unit.

Safe Brake Relay

The Safe Brake Relay allows the Power Module to be safely connected to an electromechanical motor brake, allowing the brake to be directly and safely controlled from the CU250S‑2 Control Unit in accordance with IEC 61508 SIL 2 and EN ISO 13849‑1 PL d and Category 3.

PC inverter connection kit 2

For controlling and commissioning an inverter directly from a PC if the appropriate software (STARTER commissioning tool or SINAMICS Startdrive) has been installed.

Shield connection kit for Power Modules

The shield connection kit makes it easier to connect the shields of supply and control cables, provides mechanical strain relief and thus ensures optimum EMC performance. The shield connection kit is included in the scope of delivery of PM240‑2 Power Modules, frame sizes FSA to FSF.

Line-side power components

The following line-side power components are available for SINAMICS G120 standard inverters:

Line filters

With one of the additional line filters, the Power Module attains a higher radio interference class.

Line reactors
(only for PM240‑2 Power Modules, frame sizes FSA to FSC, and PM240 FSGX)

Line reactors smooth the current drawn by the inverter and thus reduce harmonic components in the line current. Through the reduction of the current harmonics, the thermal load on the power components in the rectifier and in the DC-link capacitors is reduced as well as the harmonic effects on the supply. The use of a line reactor increases the service life of the inverter.

Note:

A DC link reactor is integrated in the PM240‑2 Power Modules FSD to FSF and therefore no line reactor is required.

Recommended line-side power components

Furthermore, this is a recommendation for additional line-side components, such as fuses and circuit breakers (line-side components must be dimensioned in accordance with IEC standards).

Additional information about the line-side power components can be found in Catalogs LV 10, IC 10 and IC 10 AO as well as the Industry Mall.

DC link components

The following DC link components are available for the SINAMICS G120 standard inverters:

Braking resistors
(for PM240 and PM240‑2 Power Modules only)

Excess energy in the DC link is dissipated in the braking resistor. The braking resistors are designed for use with PM240 and PM240‑2 Power Modules. They are equipped with an integrated braking chopper (electronic switch). There is an optional plug-in Braking Module for frame size FSGX.

Braking Module
(for PM240 Power Modules, frame size FSGX only)

A Braking Module and the matching external braking resistor are required to bring drives with a PM240 Power Module, frame size FSGX, to a controlled standstill in the event of a power failure (e.g. emergency retraction or EMERGENCY STOP Category 1) or to limit the DC link voltage during a short period of generator operation. The Braking Module houses the power electronics and the associated control circuit.

Load-side power components

The following load-side power components are available for the SINAMICS G120 standard inverters. This means that during operation with output reactors or sine-wave filters, longer, shielded motor cables are possible and the motor service life can be extended:

Output reactors
(not for PM240-2 Power Modules, frame sizes FSD to FSF, as these have an integrated DC link reactor)

Output reactors reduce the rate of voltage rise (dv/dt) and the height of the current peaks, and enable longer motor cables to be connected.

Sine-wave filters
(not for PM240‑2 Power Modules)

Sine-wave filters limit the rate of voltage rise (dv/dt) and the peak voltages on the motor winding. Similar to an output reactor, they enable the connection of longer motor cables.
