An overview of the
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 Siemens SINAMICS G120
Advantage
Modularity ensures flexibility for a drive concept that is fit for the future
Control Unit can be hot-swapped
Pluggable terminals
The modules can be easily replaced, which makes the system extremely service friendly
The integrated safety functions significantly reduce the costs when integrating drives into safety-oriented machines or systems
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.
Communications-capable via PROFINET or PROFIBUS with PROFIdrive Profile 4.0
Plant-wide engineering Siemens SINAMICS G120
Easy to handle
Wireless commissioning, operation and diagnostics via mobile device or laptop thanks to the optional SINAMICS G120 Smart Access
Connection to the Cloud MindSphere with the optionally available SINAMICS CONNECT 300 IoT Gateway
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 when PM250 Power Modules are used. This feedback capability provides enormous potential for savings because generated energy no longer has to be converted into heat in a braking resistor
Integrated USB interface for simplified, local commissioning and diagnostics
With Control Unit CU230P‑2: Application-specific functions for pumps, fans and compressors
Integrated are, e.g.:
4 freely-programmable PID controllers
Application-specific wizards
Pt1000-/LG-Ni1000-/DIN-Ni1000 temperature sensor interface
230 V AC relay
3 freely-programmable digital time switches
Detailed information can be found in Catalog D 35.
Siemens SINAMICS G120
With CU250S‑2 Control Units: Integrated positioning functionality (basic positioner EPos) supports process-related implementation of positioning tasks with a high dynamic response. Positioning can be implemented with an incremental and/or absolute encoder (SSI)
Encoder interfaces DRIVE‑CLiQ, HTL/TTL/SSI (SUB‑D) and resolver/HTL (terminal)
Vector control with or without sensors
Integrated control functionality by using BICO technology
An innovative cooling concept and coated electronic modules increase robustness and service life
External heat sink
Electronic components are not located in air duct
Control Unit that is completely cooled by convection
Additional coating of the most important components
Simple unit replacement and quick copying of parameters using an optional Operator Panel or an optional memory card
Quiet motor operation as a result of the high pulse frequency
Compact, space-saving design
Simple adaptation to 50 Hz or 60 Hz motors (IEC or NEMA motors)
2/3-wire control for static/pulsed signals for universal control via digital inputs
Certified worldwide for compliance with CE, UL, cUL, RCM, SEMI F47 and Safety Integrated according to IEC 61508 SIL 2 and EN ISO 13849‑1 PL d and Category 3
