SKD3200400 - Variable speed drive - CONTROL TECHNIQUES

Control Techniques frequency drive SKD3200400, Commander SK

The frequency drive with reference SKD3200400 belongs to the Commander SK series from CONTROL TECHNIQUES. Designed to control three-phase asynchronous motors, it is aimed at maintenance teams, system integrators and machine builders looking for a compact, reliable speed variation solution for industrial environments. Its supply range of 3 x 200-240 V AC and rated power of 4 kW (approximately 5.5 HP) make it a suitable choice for conveyor, pumping and ventilation applications, as well as general production machinery. The Commander SK series stands out for streamlined commissioning, integrated motor protection functions and an architecture engineered for plant availability. In retrofit or fast-replacement scenarios, this model fits easily into a control cabinet and delivers stable speed control, with a parameter set adapted to common industrial process requirements.

Commander SK range overview

The Commander SK series was developed to address general-purpose drive applications, offering a controlled balance between compactness, simple configuration and functional robustness. Essential functions for speed variation, start/stop, acceleration and deceleration ramps, as well as motor protection, are provided through a clear interface. The user logic enables fast, repeatable commissioning, an important point for multi-site maintenance teams and integrators deploying standard cabinets across multiple lines.

• General-purpose and easy maintenance : configuration focused on motor electrical parameters, speed settings, direction and basic safety functions, enabling quick field use.
• Range modularity : extensions and accessories available within the Commander SK family, offering I/O and communication options suited to common automation architectures.

The SKD3200400 model fits this approach by covering the 4 kW at 240 V three-phase segment, a power level widely used for accumulation conveyors, small-to-medium centrifugal pumps and industrial fan control. It therefore provides a rational technical foundation for new equipment, targeted replacements during obsolescence, or progressive upgrades of installations without heavy process requalification.

Industrial applications

With its sizing and speed control features, this drive adapts to a wide variety of continuous and cyclic processes. The device suits both integrators seeking a standardized reference for repeatable machines and maintenance teams that need to secure quick restarts with a limited stock of variants. Some relevant use cases are listed below.

• Conveyors and light material handling : control of feed speed, adaptation to throughput and material flow.
• Centrifugal pumps : optimization of operating point, reduction of water hammer with controlled ramps.
• Ventilation and air treatment : airflow adjustment, energy consumption control through speed variation.
• Packaging : control of rollers, traction adjustment according to formats and products.
• General industrial machinery : auxiliary drives, feed tables, material preparation equipment.

Integration and communication

Integration of the SKD3200400 into an automation architecture is carried out in a conventional way, with control via logic inputs and an analog speed setpoint, or via communication modules available within the Commander SK range when a network connection is required. This approach enables closed-loop operation with an existing programmable logic controller, simple synchronization with a numerical controller or use of standard safety interlocks at cabinet level. The family’s standard I/O terminals allow implementation of proven schemes, with Start, Stop, clockwise and counter-clockwise sequences, and ramps configured to suit the process.

Configuration can be performed via the local panel and the range’s configuration menus, with the ability to duplicate parameters using dedicated Commander SK accessories to standardize settings across multiple drives. For applications requiring finer torque control, the range offers advanced functions, while for very high-dynamics axis drives it is recommended to choose a specialized servo drive. As a general-purpose frequency drive, the SKD3200400 robustly covers speed variation needs while integrating cleanly with industrial standards.
