Modular design

SINAMICS G120P is a modular inverter system comprising the following components.

• CU230P?2 Control Unit
• Power Module
• Operator panel or blanking cover

CU230P?2 Control Unit

The inverter communication interface is defined when selecting the Control Unit (FW V4.5 and higher).

• CU230P?2 HVAC > USS, Modbus RTU, BACnet MS/TP, FLN P1
• CU230P?2 DP > PROFIBUS
• CU230P?2 PN > PROFINET, EtherNet/IP

The CU230P-2 Control Unit controls and monitors the Power Module and the connected motor using several different closed-loop control modes that can be selected. It supports communication to a local or central controller as well as to the monitoring equipment, and allows all process-related auxiliary equipment and external components to be connected (sensors, valves, contactors, etc.).

Power Modules

The Power Module is selected depending on the power requirement and the application. State-of-the-art IGBT technology with pulse-width modulation is used for reliable and flexible motor operation. Comprehensive protection functions provide a high degree of protection for the Power Module and the motor.

Power Modules in degree of protection IP20 are intended for installation in a control cabinet.

• PM230 with integrated filter class A, degree of protection IP20, 0.37 kW to 75 kW (0.5 to 101 hp)
• PM230 without integrated line filter, degree of protection IP20, 0.37 kW to 75 kW (0.5 to 101 hp)
• PM230 with integrated filter class A, degree of protection IP20 Push Through variant, 3 kW to 18.5 kW (4 to 24.8 hp)
• PM230 without integrated line filter, degree of protection IP20 Push Through variant, 3 kW to 18.5 kW (4 to 24.8 hp)
• PM240 with integrated filter class A, degree of protection IP20, 90 kW (121 hp)
• PM240 without integrated line filter, degree of protection IP20, 110 kW and 132 kW (148 and 177 hp)
• PM330 without integrated line filter, degree of protection IP20, 160 kW to 630 kW (215 to 845 hp)

Power Modules in degree of protection IP55 can be erected as distributed units outside a control cabinet.

• PM230 with integrated filter class A, degree of protection IP55/UL Type 12, 0.37 kW to 90 kW (0.5 to 121 hp)
• PM230 with integrated filter class B, degree of protection IP55/UL Type 12, 0.37 kW to 90 kW (0.5 to 121 hp)

SINAMICS G120P units rated for outputs of 110 kW (148 hp) and higher are also available as control cabinet version SINAMICS G120P Cabinet.

• SINAMICS G120P Cabinet, degrees of protection IP20/IP21/IP23/IP43/IP54, 110 kW to 630 kW (148 to 845 hp), with and without line filter

Operator panel or blanking cover

• Intelligent Operator Panel IOP, degree of protection IP54/UL Type 12
  The IOP supports entry-level personnel and drive experts. Thanks to the large plain text display, the menu-based operation and the application wizards, it is easy to commission, diagnose and locally control standard drives. Optionally available wizards ¹⁾ interactively guide users through the commissioning process.
• Basic Operator Panel BOP?2, degree of protection IP55/UL Type 12
  The menu prompting and the 2-line display facilitate fast and user-friendly commissioning of the inverter. Simultaneous display of the parameter and parameter value, as well as parameter filtering, means that basic commissioning of a drive can also be performed without a printed parameter list.
• Blanking cover, degree of protection IP55/UL Type 12
  The blanking cover is mounted on the Power Module in place of an operator panel, provided that an operator panel is not required.

The operator panel supports user-friendly local commissioning, control and diagnostics and enables complete inverter data sets to be pre-parameterized and cloned.

Note regarding PM230 Power Modules in degree of protection IP55/UL Type 12:
It is essential to plug on an operator panel or the blanking cover in order to achieve degree of protection IP54/IP55/UL Type 12.

Line-side power components

The following line-side power components are available for the SINAMICS G120P inverters:

• Line filters for PM230, PM240, PM330 Power Modules and SINAMICS G120P Cabinet
  With an additional line filter, the Power Module complies with a higher radio interference class.
• Line reactors for PM240, PM330 Power Modules and SINAMICS G120P Cabinet
  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.
  SINAMICS G120P Cabinet units feature a cabinet-integrated line reactor as standard.

Note:
A line reactor must not be used in combination with a PM230 Power Module.

Recommended line-side power components

This section contains recommendations 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 listed fuses and circuit breakers can be found in Catalogs LV 10, IC 10 and IC 10 AO.

DC link components

The following DC link components are available for the SINAMICS G120P inverters:

• Braking Module for PM330 Power Modules and SINAMICS G120P Cabinet
  A Braking Module and the matching braking resistor are required to achieve controlled braking of a drive. The Braking Module houses the power electronics and the associated control circuit.
• Braking resistors for PM240, PM330 Power Modules and SINAMICS G120P Cabinet
  Excess energy in the DC link is dissipated via the braking resistor.

Load-side power components

Various load-side power components are available for the SINAMICS G120P inverters. These allow the use of longer shielded motor cables and increase the motor service life:

• Output reactors
  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 for PM230 and PM240 Power Modules
  Sine-wave filters limit the 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.
• dv/dt filters plus VPL for PM330 Power Modules
  dv/dt filters plus VPL (Voltage Peak Limiter) limit the voltage rate-of-rise dv/dt to values of <500 V/?s and the typical voltage peaks to values according to the limit value curve according to IEC/TS 60034-17: 2006.
  Standard motors with standard insulation and without insulated bearings can be used for inverter operation if a dv/dt filter plus VPL is used.
• dv/dt filters compact plus VPL for PM330 Power Modules and SINAMICS G120P Cabinet
  dv/dt filters compact plus VPL (Voltage Peak Limiter) limit the voltage rate-of-rise dv/dt to values of <1600 V/?s and the typical voltage peaks to values according to the limit value curve A to IEC 60034?25: 2007.
  Standard motors with standard insulation and without insulated bearings can be used for inverter operation if a dv/dt filter compact plus VPL is used.
