01 / PRODUCT POSITIONING

Compact drive architecture,
built around integration.

SINAMICS G120C is designed as a compact converter family covering a wide power range. The 6SL3210-1KE14-3AF2 occupies the 1.5 kW position in the 380–480 V three-phase, FSAA filtered range.

Integrated functions reduce the need for separate drive-side hardware while keeping communication, I/O and safety functions within the converter architecture.

INTEGRATED DRIVE FUNCTIONS

Filter + I/O + STO + PROFINET

The selected G120C variant combines a Class A integrated line filter, digital and analog interfaces, motor-temperature sensing, Safe Torque Off and PROFINET communication in one compact converter.

02 / KEY FEATURES

What makes this G120C configuration distinctive

Class A filter

The 6SL3210-1KE14-3AF2 incorporates an integrated Class A line filter, making it a filtered G120C configuration rather than the unfiltered variant.

PROFINET PN

PROFINET is integrated as the fieldbus interface, allowing the converter to fit into industrial Ethernet-based automation architectures.

Integrated STO

Safe Torque Off is integrated into the drive, supporting safety-oriented machine designs where the motor torque must be safely disabled.

Compact FSAA

The FSAA package measures approximately 173 × 73 × 160 mm, giving the 1.5 kW converter a compact installation footprint.

03 / TECHNICAL SPECIFICATION

04 / LOAD BEHAVIOR

Two rating profiles,
one compact platform.

The selected model has separate low-overload and high-overload ratings. This distinction matters when matching the converter to the actual motor load profile.

LOW OVERLOAD

1.5 kW

150% for 3 s

110% for 57 s

100% for 240 s

HIGH OVERLOAD

1.1 kW

200% for 3 s

150% for 57 s

100% for 240 s

WHY IT MATTERS

Application matching

Select the rating profile according to the required motor power, current and overload behavior.

05 / APPLICATION & DOWNTIME

Where the 6SL3210-1KE14-3AF2 becomes critical

SYSTEM ROLE

Machine motor control

G120C compact converters are intended for industrial motor-drive applications. The 1.5 kW class of this model is suitable for smaller motor loads where controlled speed and torque are required.

Typical application logic
A three-phase motor → G120C converter → machine mechanism, with control commands and diagnostics handled through the drive interface.

SCENARIO 01

Drive will not run

If the converter becomes unavailable, the motor-driven machine section may remain stopped even when upstream automation is still operational.

SCENARIO 02

PROFINET communication issue

A network-side problem involving the drive can interrupt normal command exchange with the automation controller and extend machine recovery time.

SCENARIO 03

Replacement identification

Searching by the complete 6SL3210-1KE14-3AF2 number is important because G120C variants differ in communication interface, filtering and configuration.

Downtime perspective: when a drive is a critical motor-control element, waiting for a compatible replacement can keep a machine section unavailable. Correct article-number matching helps avoid introducing the wrong fieldbus or filter variant during an urgent replacement.

06 / SINAMICS G120C FAMILY

Same platform, different engineering priorities

SINAMICS G120C covers multiple power ratings, frame sizes and communication variants. The 6SL3210-1KE14-3AF2 belongs to the FSAA group and combines 1.5 kW low-overload capability with integrated Class A filtering and PROFINET.

LOWER POWER

1.1 kW class

Smaller motor applications within the same G120C family.

THIS MODEL

6SL3210-1KE14-3AF2

1.5 kW, Class A filter, PROFINET, FSAA.

NEXT POWER STEP

2.2 kW class

Higher motor-power requirement within the compact G120C range.

LARGER FRAME

FSA / beyond

Larger G120C frame sizes cover higher power ranges.

Important selection point: G120C variants should not be treated as interchangeable solely because they share the same family name. Power rating, fieldbus, filter configuration, frame size and I/O arrangement all matter.

07 / BUYER-FOCUSED FAQ

Five questions worth checking before purchase

These questions focus on the points most likely to affect replacement compatibility, commissioning effort and machine downtime.

Q1 — Is 6SL3210-1KE14-3AF2 the right G120C variant if the machine already uses PROFINET?

This model has an integrated PROFINET-PN fieldbus interface, so it is specifically configured for PROFINET-based communication. That makes the complete article number important when replacing a G120C with another communication variant.

Q2 — Why does 6SL3210-1KE14-3AF2 have both 1.5 kW and 1.1 kW ratings?

The two values correspond to different overload classifications. The low-overload rating is 1.5 kW, while the high-overload rating is 1.1 kW. The appropriate rating depends on the actual motor load profile and overload requirement.

Q3 — Does 6SL3210-1KE14-3AF2 already include the EMC filter required by the selected configuration?

Yes. The article number identifies the G120C configuration with an integrated Class A line filter. This is an important distinction from corresponding unfiltered G120C variants when matching an existing installation.

Q4 — What should I compare before ordering 6SL3210-1KE14-3AF2 as a failed-drive replacement?

Compare the complete article number, input voltage, motor power requirement, overload class, fieldbus interface, filter configuration, frame size and I/O arrangement. Matching only the 1.5 kW rating is not sufficient.

Q5 — How can 6SL3210-1KE14-3AF2 affect downtime when a production motor stops?

If this converter controls a production-critical motor, a failed drive can keep the associated machine section unavailable. Because the G120C also handles communication and safety-related drive functions, identifying the correct variant quickly can reduce replacement delays.

Purchase check: send the complete article number together with the machine/system information before ordering.

08 / INSTALLATION CONDITIONS

Compact hardware,
defined limits.

The converter uses integrated fan cooling and is intended for defined ambient conditions. These limits should be considered when replacing a drive in an existing cabinet.

OPERATION
