6SE3213-2CB40 - Inverter - SIEMENS

Siemens 6SE3213-2CB40, MICROMASTER, variable frequency drive for precise control of your drives

The variable frequency drive SIEMENS 6SE3213-2CB40 belongs to the MICROMASTER series, widely used in industry for controlling asynchronous motors. This model meets the needs of maintenance teams, system integrators and engineering departments seeking a robust solution for speed regulation, energy optimization and service continuity. Designed for conveyor, pumping, ventilation and small special-machine applications, this drive allows precise adjustment of the motor supply frequency to achieve the required speed with measurable operational stability. Compatibility with the series' control methods, user-friendly parameter setup and straightforward integration into an automation architecture make it a relevant choice for restoring existing installations, while minimizing unplanned downtime and securing the process.

Reliable control, stable process, optimized maintenance

• Precise motor speed control – Frequency variation provides accurate regulation to adapt flow, torque and speed to process requirements, directly impacting quality and repeatability.
• Smooth start and stop – Configurable ramps limit inrush currents, reduce mechanical stress and extend the lifetime of drives and transmission components.
• Reduced operating costs – By matching speed to load, the drive improves energy efficiency, notably for pumps and fans where affinity laws apply.
• Smooth integration with automation – The series' standard digital and analog inputs simplify control from a programmable logic controller or an operator panel, without recoding existing installations.
• Service continuity and retrofit – Easy replacement of older MICROMASTER drives or other inverters to quickly restore production using known parameters and a proven commissioning methodology.

Key features of the MICROMASTER series, focused on reliability

The 6SE3213-2CB40 follows the functional architecture typical of the MICROMASTER series drives for three-phase asynchronous motors. Regulation is achieved by frequency variation, with control modes available in the series such as the V/f law and, depending on configuration, more advanced control for enhanced dynamics. Commissioning relies on a clear terminal layout and parameters structured into functional groups, which reduces intervention time during emergency replacements. The series' internal protection functions, such as thermal monitoring of the power module, overcurrent handling and DC bus supervision, are designed to safeguard the drive and prevent recurring faults linked to operating conditions. The local interface of the series, via an operator panel when fitted, makes it easy to access real-time values, diagnostics and primary adjustments without proprietary software tools. For system integration, the series offers control via digital (on/off) and analog signals, as well as extension options through MICROMASTER-specific communication option cards, allowing data exchange with common architectures. This modular approach helps standardize spare parts and limit the variety of stocked references.

Applications and operating environments

The 6SE3213-2CB40 targets small to medium power industrial drives where speed accuracy and repeatability are critical. It is particularly suitable for handling conveyors, utility pumps and fans, dosing and mixing equipment in process plants, as well as assembly and packaging machines. The unit integrates naturally into cells controlled by a programmable logic controller or a numerical control when only speed control is required. It is not intended to replace a servo drive in positioning applications that require closed-loop encoder feedback, but it is a practical solution when a stable, repeatable speed regulation is the priority.

Differentiation, SIEMENS reliability and SEI support

The MICROMASTER series benefits from a large installed base, extensive documentation and standardized commissioning practices. This industrial continuity facilitates minimizing downtime, training staff and maintaining operational readiness. Coupled with the reputation of SIEMENS in automation, it provides a reliable technical framework for maintenance and retrofit. Standard Exchange Industry offers solutions for supply and standard exchange, as well as a repair service for drives. Each unit is tested on a test bench according to documented procedures. Shipments are made within 24 to 72 hours, and services are covered by a warranty in accordance with our policy, specified according to the selected service. Our technical support assists you in identifying the reference, verifying compatibility with the motor and the network, and transferring parameters to secure the restart.

To confirm the suitability of the 6SE3213-2CB40 for your installation, we recommend recording the motor nameplate, available supply voltage, rated current and the control requirements from the programmable logic controller. This methodology, in line with maintenance best practices, allows precise drive parameterization, ramp optimization and validation of protections to achieve stable and durable regulation.
