Key Features

1. 11 kW Low Overload Capacity

Under the Low Overload (LO) condition, the rated power is 11 kW, enabling a continuous 3-second operation at 150% basic load current and 57 seconds at 110% load. In the High Overload (HO) condition, the rated power is 7.5 kW and supports higher instantaneous overload capacity.

2. Integrated PROFINET Communication

The Siemens 6SL3210-1KE22-6UF1 integrates PROFINET-PN, connecting PLC, HMI and industrial automation networks, suitable for centralized control and equipment status monitoring.

3. Support for Multiple Control Modes

Supports linear V/f, square V/f, parameterizable V/f, FCC and sensorless vector control, allowing parameter configuration based on different load characteristics of actual applications.

4. Integrated Safety Function

Siemens 6SL3210-1KE22-6UF1 built-in Safe Torque Off (STO), suitable for industrial drive systems that require safe shutdown function, help to build the corresponding mechanical safety control scheme.

5. Rich I/O Interfaces

Equipped with 6 digital inputs, 2 digital outputs, 1 differential analog input and 1 analog output, and provides a motor temperature sensor interface, capable of meeting the signal acquisition and control requirements of common industrial equipment.

Typical applications

Fans and ventilation equipment
Pumps and industrial pump sets
Conveyor belt
Packaging machinery
Production line drive
Material handling equipment
Machining equipment
Industrial automation equipment
General motor speed control system

Which control methods are supported?

V/f linear control
V/f square control
Parametric V/f
V/f + FCC (flux current control)
V/f ECO
Sensorless vector control

Does the 6SL3210-1KE22-6UF1 model have safety features?

Yes. Integrated Safe Torque Off (STO) and equipped with a fail-safe digital input can be used for the corresponding machine safety control.

Can other G120C frequency converters be directly replaced?

Direct replacement based on power alone is not recommended. Although the power ratings of different G120C models may vary, the communication protocol, whether a filter is included, and the order configuration may also differ. You can contact us if the production is stopped and we will find a replacement solution for you.

What is the overload capacity of 6SL3210-1KE22-6UF1?

1. In the low overload (LO mode):

150% of the basic load current, for 3 seconds;
110% of the basic load current, for 57 seconds.

2. In the high overload (HO) mode:

200% of the basic load current, for 3 seconds;
150% of the basic load current, for 57 seconds.

Our quality

1. Support for compliance documents such as CE / UKCA

Our improved Siemens 6SL3210-1KE22-6UF1 belongs to the G120C series of products and has a Declaration of Conformity and UK Declaration of Conformity documents.

2. Pre-delivery quality inspection

To mitigate the procurement risks for low industrial automation spare parts, we can conduct checks on the model, nameplate, appearance and packaging of the product before delivery:
Are the nameplate and order number clear and complete?
Are there any abnormalities in the product appearance and terminals?
Is the packaging intact?
Are the technical parameters consistent with the purchase order?
Are the accompanying documents complete?
