SK1,5ML - Variable speed drive - LEROY SOMER

Variateur de fréquence Leroy Somer SK1,5ML, gamme DIGIDRIVE SK

The reference SK1,5ML belongs to the DIGIDRIVE SK range by Leroy Somer, a family of variable-frequency drives designed to control asynchronous motors in industrial environments. This model addresses speed regulation needs on equipment such as conveyors, pumps, fans, mixers or machine feed systems where process stability, reduced mechanical wear and energy optimisation are required. With a single-phase 100/120 V supply identified by the ML code, it fits easily into light installations, standalone machines or production stations requiring a reliable and repeatable motor control. The rated motor power of 0.75 kW is suitable for low-power drives while offering the flexibility of continuous speed variation to finely adjust flow, cycle rate or belt tension. The DIGIDRIVE SK is recognised for its pragmatic implementation and compatibility with standard asynchronous motors, which simplifies both on-site replacement and integration during retrofits of existing installations facing obsolescence.

Présentation de la gamme DIGIDRIVE SK

The DIGIDRIVE SK series groups variable-frequency drives engineered to meet common industrial automation requirements, with straightforward commissioning and consistent performance over time. The modular approach of the range allows addressing simple or distributed architectures, both for new installations and replacements, while maintaining compatibility with the asynchronous motors widely used in industry. Identification by codes simplifies selection, for example the ML suffix for single-phase 100/120 V supplies. The basic process-oriented functions focus on speed regulation, control of acceleration and deceleration ramps, and setpoint consistency to stabilise production quality. As part of a maintenance strategy, the range offers a compromise between compactness, energy efficiency and ease of operation, making it a relevant solution for many transfer, fluid handling or ventilation applications.

• Reliable speed control : continuous frequency adjustment to match speed and torque to the process load.
• Simplified integration : terminals and control logic designed for rapid commissioning depending on version and application diagram.

The SK1,5ML model follows this universal-use approach for low-power asynchronous motors, targeting needs for speed variability, repeatability and cycle-time control in production contexts where equipment availability and ease of replacement are decisive.

Applications industrielles

With a rated power of 0.75 kW and a single-phase 100/120 V supply, the SK1,5ML suits a wide range of applications seeking precise speed control without excessive complexity. It is appropriate for standalone machines, subsystems of larger equipment, as well as targeted modernisations of stations affected by obsolete drives. Typical examples of use:

• Conveying and light handling : cadence adjustment, simple synchronization between belt or roller sections.
• Pumping and fluid transfer : flow adaptation to reduce hydraulic shocks and stabilise pressure.
• Ventilation and air handling : fan speed modulation to adjust air renewal and limit consumption.
• Packaging : control of auxiliary drives, feed rollers and variable-speed ejectors.
• Food and textile : control of belt tension, process regularity on low-power unit stations.

Intégration et communication

The SK1,5ML integrates into an automation architecture in a conventional way with asynchronous motor control. Depending on the version and equipment, the speed setpoint and enable signals can be managed by the plant PLC, allowing alignment of drive speed with process requirements. Frequency variation ensures continuity of control and coherence of ramps to preserve mechanical components and limit stress on the driven load.

Configuration and maintenance follow established industrial practices. Regulator function setup relies on standard parameters for a drive in this range, with a focus on setpoint quality and speed stability. When replacing an older drive, compatibility with standard asynchronous motors simplifies retrofits and reduces downtime. For new installations, integration remains clear for maintenance teams, easing long-term follow-up and documentation management.
