Siemens 6SL3210-1KE14-3AF2 SINAMICS G120C Compact Converter
A compact filtered drive with integrated PROFINET communication and Safe Torque Off for standard machinery.
Technical Summary
6SL3210-1KE14-3AF2 combines the power section, control electronics, I/O and network interface in one SINAMICS G120C converter. Its exact suffix identifies a PROFINET version with an integrated Class A filter and an externally supplied control circuit.
The compact construction suits machine designs that need networked speed control without assembling a modular power module and separate Control Unit.

Features
- Integrated converter architecture reduces the number of separately selected drive components.
- Encoderless vector and configurable V/f control modes support common variable-speed motor duties.
- Front-access I/O and network connections simplify cabinet commissioning and diagnostics.
- External control-power capability supports the intended automation design when main power is unavailable.
Compatibility
- Use with a three-phase motor whose current, thermal data and duty cycle fit the converter selection.
- Connect the unit to a compatible PROFINET controller and retain the device-name and telegram configuration.
- Choose line protection, cable shielding and motor-side accessories from the applicable SINAMICS engineering rules.
Replacement
- Back up parameters, motor data, network identity and safety settings before removing the installed converter.
- Compare the complete MLFB, not only the G120C family and power class, because filter and communication variants differ.
- After exchange, restore the controlled parameter set and validate rotation, ramps, I/O, fieldbus and the safety function.
FAQ
Can 6SL3210-1KE14-3AF2 replace an unfiltered G120C variant?
Only after the EMC concept, leakage-current implications and article-level compatibility have been reviewed; the filter option is part of the ordered construction.
What network information is needed for 6SL3210-1KE14-3AF2?
Provide the PROFINET device name, IP settings, controller hardware configuration, telegram and any topology or redundancy requirements.
Does 6SL3210-1KE14-3AF2 remove the need for a safety review?
No. The integrated safety function must remain wired, parameterized and validated within the machine safety design.
Which records prevent a mismatched 6SL3210-1KE14-3AF2 spare?
Supply the complete nameplate, parameter backup, motor rating plate, panel schematic and communication assignment.
Can an older parameter file be loaded into 6SL3210-1KE14-3AF2 without checking firmware?
The project and device firmware should be checked together before download so that parameters and commissioning tools remain compatible.
What should be tested after installing 6SL3210-1KE14-3AF2?
Verify motor direction, current behavior, ramps, digital and analog signals, network control, fault handling and the documented safe-stop response.
