SIEMENS SINAMICS G120C
Compact Frequency Converter
Product Overview
The Siemens SINAMICS G120C 6SL3210-1KE15-8AF2 is a compact, high-performance frequency converter / variable frequency drive (VFD) designed for reliable speed and torque control of three-phase motors in industrial automation applications.
This model is rated for 3 AC 380–480 V, with a 2.2 kW low-overload (LO) rating and 1.5 kW high-overload (HO) rating. It features an integrated Class A EMC filter, PROFINET communication, integrated Safe Torque Off (STO), and a comprehensive 24 V I/O interface. Its compact FSAA frame size makes it particularly suitable for space-constrained control cabinets and machine applications.
Key Features
High-Performance Motor Control
Provides reliable speed and torque control for three-phase asynchronous motors and supports multiple control methods, including V/f control, V/f ECO, and sensorless vector control.
2.2 kW Low-Overload Rating
The converter provides a rated output power of 2.2 kW under the low-overload duty cycle, corresponding to 5.60 A rated output current.
1.5 kW High-Overload Rating
For applications requiring higher overload capability, the unit provides 1.5 kW with a rated output current of 4.10 A.
Integrated PROFINET Interface
Built-in PROFINET PN connectivity enables direct integration into Siemens automation architectures and Industrial Ethernet-based control systems.
Integrated Safe Torque Off
The converter includes Safe Torque Off (STO) as a standard integrated safety function, supporting machine-safety architectures where controlled prevention of motor torque is required.
Integrated EMC Filter
An integrated Class A EMC filter helps reduce conducted electromagnetic interference and supports compliance with applicable industrial EMC requirements.
Comprehensive I/O
The standard interface includes 6 digital inputs, 2 digital outputs, 1 analog input, 1 analog output, and 1 motor-temperature input.
Compact Cabinet Design
The FSAA housing measures only 173 × 73 × 160 mm (H × W × D), providing a compact solution for machine builders and panel designers.
