Overview of the Commander SK range

The Commander SK series was developed to provide reliable frequency control, easy integration and simplified maintenance. It covers continuous variable speed applications where control accuracy and operational robustness are priorities. Commander SK drives are often chosen for retrofits of existing lines when production continuity and compatibility with programmable logic controllers of different generations are essential. The consistent menu structure and availability of communication and I/O accessories facilitate standardisation on site.

• High-performance motor control : stable speed regulation for induction motors, with clear configuration of ramps, safety thresholds and energy-saving functions
• Modular expandability : extension cards and modules available across the range to meet communication, I/O and advanced commissioning requirements

Beyond basic functions, the range focuses on EMC compatibility, energy optimisation through frequency adjustment and reduction of mechanical wear on driven components. It meets the needs of continuous operation with clear diagnostics and integrated protections, while avoiding the complexity of servo drives intended for very dynamic motion. This makes it a reference solution for many production workshops and industrial utilities.

Industrial applications

The SKA1100025 drive is intended for recurring variable-speed drive tasks, with an emphasis on reliability, energy efficiency and ease of tuning.

• Conveying and light handling : stable speed control for belts and rollers, simple section-to-section synchronisation
• Pumps and fluid processes : flow adjustment, reduction of water hammer thanks to controlled ramps
• Industrial ventilation and HVAC : air flow adaptation for energy savings and operator comfort
• Assembly machines and utilities : auxiliary motors, peripheral drives and feed stations
• Packaging and light processing : adjustable cycle rates, smooth transitions during start and stop phases

Integration and communication

Integration of the Commander SK into an automation architecture is done via its standard I/O and, depending on options available in the range, by adding communication cards for common industrial fieldbuses. This modular approach simplifies interfacing with multibrand programmable logic controllers and numerical controls dedicated to specialised machines. Basic functions cover common needs for remote control, setpoint selection and status feedback.

For commissioning, the series provides direct access to essential parameters, a rational menu structure and software tools available depending on configuration. Best installation practices, notably motor cabling management, protection against EMC disturbances and respect for ventilation distances, ensure long-term performance and compliance with applicable standards. Altogether this delivers reliable speed regulation without excessive complexity, consistent with the requirements of a frequency inverter designed for standard industrial applications.
