Особенности
- Compact and space-saving design with slimline type of construction and identical drilling template for all outputs
- Wide output range from 0.75 to 7.5 kW.
- The safety functions make it easier to integrate drives into safety-oriented machines or plants
- The innovative circuit design (bidirectional input rectifier with "pared-down" DC link) allows the kinetic energy of a load to be fed back into the supply system. This feedback capability provides enormous potential for savings because generated energy no longer has to be converted into heat in a braking resistor. Braking resistors and reactors are not necessary - this is a particular advantage in terms of the space requirement and installation costs for the high IP65 degree of protection.
- Enhanced ruggedness and longer service life due to coating of the electronic modules
- Flexibility due to modularity for a future-oriented distributed drive concept to the high IP65 degree of protection
- Every development stage of a component can improve the existing drive system
- Module replacement when system is running (hot swapping)
- The modules can be easily replaced, which makes the system extremely service friendly.
- Capable of communicating via PROFIBUS with PROFIdrive Profile 4.0
- Reduced number of interfaces
- Plant-wide engineering
- Easy to handle
- The ability to connect up to six sensors and up to two actuators directly to the Control Unit means that almost all drive information can be directly managed; local preprocessing of the signals takes the load off the fieldbus.
- Integrated EMC filter of class A (according to EN 55011), integrated braking control (400 V 1 AC rectified, corresponds to 180 V DC) and integrated motor protection due to thermal motor model and evaluation of PTC or KTY 84 temperature sensors
- Software parameters for easy adaptation to 50 Hz or 60 Hz motors (IEC or NEMA motors)
- Easy replacement of devices and time-saving copying of parameters with the optional MMC memory card
- Engineering and commissioning with uniform engineering tools such as SIZER (Version 2.9 and higher), STARTER (Version 4.1, SP1 and higher) and Drive ES: Ensure rapid engineering and easy commissioning – STARTER is integrated in STEP 7 with Drive ES Basic with all the advantages of central data storage and totally integrated communication
- Certified worldwide for compliance with CE, UL, cUL, C-tick and Safety Integrated according to EN 954-1, Cat. 3 and IEC 61508 SIL 2
Дизайн
The SINAMICS G120D distributed frequency inverters are modular frequency inverters for standard drives. Each SINAMICS G120D comprises two operative units – the Power Module and Control Unit.
Power Module PM250D and Control Unit CU240D
Power Module PM250D with line and motor connections and Control Unit CU240D
Power Modules
The following Power Modules are available for SINAMICS G120D distributed frequency inverters:
PM250D Power Modules
PM250D Power Modules use an innovative circuit design which allows line-commutated energy recovery to the supply. This innovative circuit permits generator energy to be fed back into the supply system and, therefore, saves energy.
Accessories
Connector sets for line infeed and the outgoing motor feeder are available as accessories as well as pre-assembled motor cables for connection to the motor.
Control Units
The following Control Units are available for SINAMICS G120D distributed frequency inverters:
CU240D Control Units
The Control Unit performs closed-loop control functions for the inverter. In addition to control functions, the Control Unit can also perform other tasks which can be adapted to the relevant application by parameterization. A number of Control Units are available in different versions:
- CU240D DP
- CU240D DP-F
- CU240D PN (available soon)
- CU240D PN-F (available soon)
Accessories
The parameter settings for an inverter can be stored on the MMC memory card. When the plant is serviced, it is immediately ready for use again after, for example, replacement of the frequency inverter and transfer of the memory card data. The associated slot is located on the rear of the Control Unit.
- RS232 interface cable for communication with a PC
For controlling and commissioning an inverter directly from a PC if the appropriate software (STARTER Version 4.1, SP1 and higher) has been installed. The commissioning tool STARTER is included in the scope of supply of the Control Unit on CD-ROM.
A spare parts kit is available which comprises small parts such as seals, cover caps, PROFIBUS address windows and screws.
Конфигурация
The following electronic configuration and engineering tools are available for SINAMICS G120D distributed frequency inverters:
Selection guide for SD configurator within the CA 01
The interactive catalog CA 01 – the offline mall of Siemens Automation and Drives (A&D) – contains over 100000 products with approximately 5 million potential drive system product variants. The SD configurator has been developed to facilitate selection of the correct motor and/or inverter from the wide spectrum of A&D SD products. The configurator is integrated in this catalog with the selection and configuration tools as a "selection guide" on CD 2 "Configuring".
SIZER configuration tool
The SIZER PC tool provides an easy-to-use means of configuring the SINAMICS and MICROMASTER 4 drive family. It provides support when setting up the technologies involved in the hardware and firmware components required for a drive task. SIZER supports the complete configuration of the drive system, from simple individual drives to complex multi-axis applications. For SINAMICS G120D as from SIZER Version 2.9.
STARTER drive/commissioning software
The STARTER drive/commissioning software provides menu-guided assistance with commissioning, optimization and diagnostics. STARTER is not only designed for use on SINAMICS drives but also for MICROMASTER4 units and frequency inverters for the distributed I/O SIMATIC ET 200S FC. For SINAMICS G120D from STARTER Version 4.1, SP1.
Drive ES engineering system
Drive ES is the engineering system used to integrate Siemens drive technology into the SIMATIC automation world easily, efficiently and cost-effectively in terms of communication, configuration and data management. The STEP 7 Manager user interface provides the basis for this procedure. A variety of software packages, i.e. Drive ES Basic, Drive ES SIMATIC and Drive ES PCS 7, is available for SINAMICS.
