SKCD200220 - Variable speed drive - CONTROL TECHNIQUES

Control Techniques SKCD200220 Frequency Inverter - DIGIDRIVE SK

The frequency inverter SKCD200220 belongs to the DIGIDRIVE SK range from Control Techniques. This series is dedicated to driving AC induction motors in industrial environments where speed control, energy optimisation and operational availability are priorities. With a rated power of 2.2 kW, a 200/240 V single-phase or three-phase supply and electrical characteristics suited to common workshop needs, this model effectively covers pumping, ventilation, conveying and light automation applications. Maintenance teams, integrators and line operators will find a standardised, robust solution to regulate motor supply frequency, stabilise processes and reduce mechanical stress related to direct-on-line starts. The DIGIDRIVE SK philosophy emphasises pragmatic commissioning, well-proportioned essential functions and consistent integration into existing automation architectures, with fieldbus compatibility available across the range via options. The objective is clear: provide an AC drive that is simple to deploy, measurably efficient and durable over time.

Overview of the DIGIDRIVE SK range

The DIGIDRIVE SK series is a family of general-purpose AC drives widely used in industry for simple to intermediate speed regulation needs. It positions itself as a reliable, pragmatic solution for modernising installations, replacing existing drives or equipping new machines. The approach focuses on the essential function of frequency variation, consistent parameter sets and compatibility with standard workshop commissioning practices. The series' designs favour mechanical and electrical integration without excessive complexity while maintaining a broad application spectrum, from ventilation to intralogistics, dosing, packaging and light handling.

• Universal control of induction motors : motor speed control by adjusting frequency and voltage, promoting process stability and reducing mechanical stress
• Measurable energy efficiencies : fine adaptation of operating point, particularly relevant for variable-torque loads such as pumps and fans
• Modular option architecture : communication extension possibilities across the range, easing integration with automation systems

The SKCD200220 model fits this approach by covering the 2.2 kW range, with 200/240 V supply in single or three-phase. This power rating is commonly used for light conveyor drives, auxiliary pumping circuits, process fans or low- to medium-power mixers, offering a rational compromise between performance, compactness and operational simplicity.

Industrial applications

This frequency inverter meets the needs of many industrial installations seeking reliable and repeatable speed control. Appropriate control of AC motors reduces inrush currents at start-up, improves mechanical endurance and stabilises flows, belt speeds or pressures. The series is readily adopted by maintenance and automation teams for commissioning, parameter optimisation and supervision during continuous operation.

• Conveying and intralogistics : speed adjustment for assembly lines, sorting and light handling
• Pumping : flow and pressure regulation for utility circuits, dosing stations and auxiliary loops
• Ventilation and air treatment : fan control for energy savings on variable-torque loads
• Light industrial automation : drives for packaging, bagging or conditioning equipment
• Food industry and various processes : mixers, transfers and machine auxiliaries

Integration and communication

Integration of the SKCD200220 into an automation architecture is performed in a standard way, with connection to a 200/240 V network, handling of control signals and adaptation to upstream protections. The DIGIDRIVE SK philosophy allows structured parameterisation, with access to essential functions such as ramping, current limiting, frequency setpoint and motor protections. Common control modes in the series include V/f and sensorless vector open-loop, depending on configuration, meeting the requirements of most general-purpose AC drives.

The DIGIDRIVE SK range offers industrial communication options via optional cards available for the family, facilitating exchange with a programmable logic controller over widely used fieldbuses such as Modbus RTU, CANopen, PROFIBUS-DP or DeviceNet, depending on options and versions. This connectivity enables the drive to be integrated into multi-vendor topologies, centralise setpoints and status feedback, and standardise maintenance within the control system.
