SK1M - Variable speed drive - LEROY SOMER

Frequency inverter Leroy Somer SK1M - DIGIDRIVE SK

The reference frequency inverter SK1M belongs to the DIGIDRIVE SK series from Leroy Somer. Intended for maintenance workshops, integrators and industrial operators, it meets speed variation needs for three-phase induction motors when the available supply is single-phase 200 to 240 V. This model covers a rated power of 0.37 kW, making it a relevant solution for low-power drives, with stable regulation and controlled energy efficiency. It is aimed at conveyor, pumping and ventilation applications where speed holding, soft acceleration and reduced mechanical stress extend equipment life. The DIGIDRIVE SK series stands out with a compact architecture, integrated protection functions and clear parameter logic to minimise downtime and simplify interventions in production environments.

Overview of the DIGIDRIVE SK range

The DIGIDRIVE SK series groups compact frequency inverters designed for regulation of induction motors in industrial environments requiring robustness, service continuity and simple parameterisation. It targets general drive applications where speed stability and torque control improve process repeatability while limiting mechanical jolts. The design favours a clear interface, stepwise commissioning logic and field-oriented features to reduce downtime during troubleshooting and replacement.

• Standard V/f control : suited to core speed regulation functions, centrifugal loads and variable-torque systems
• More dynamic control : sensorless vector control options available depending on series configuration, for more precise response in some applications

The SK1M model follows this approach of a reliable drive, modular in functionality, to meet production line and utilities unit constraints. It facilitates standard exchange or progressive modernisation of existing installations when parts availability and functional compatibility are critical.

Industrial applications

This Leroy Somer frequency inverter integrates into many operational contexts where speed variation conditions process performance, energy consumption and the quality of the finished product. It provides an effective answer for maintenance teams seeking a documented and repeatable solution for low-power drives.

• Conveyors and sorting : fine speed adjustment to synchronise flows, reduce impacts and stabilise throughput
• Centrifugal pumps : speed adaptation to control flow and pressure, with soft starts
• Ventilation and extraction : fan speed adjustment for air control and energy optimisation
• Light handling : control of rollers, tables and auxiliary mechanisms requiring simple, robust variation
• Packaging and food industry : maintaining a constant, repeatable rate on low-power motorised stations

Integration and communication

Integration of the SK1M into a control cabinet is eased by its compact format and an intuitive parameterisation interface. Standard functions of a drive in this range allow configuration of ramps, protection thresholds and speed reference sources. Common automation inputs and outputs ensure direct implementation with the programmable logic controller (PLC), with the possibility to use local controls for testing and maintenance operations.

Depending on DIGIDRIVE SK series configuration, industrial communication links can be added via modules to exchange data with the I/O island, supervision or motion controllers. This approach ensures coherent integration into existing automation architectures while retaining simple local parameterisation for commissioning or quick replacement operations. The range documentation and standardised wiring diagrams contribute to methodical, repeatable and controllable commissioning.
