Overview of the DIGIDRIVE SK range

The DIGIDRIVE SK series was developed to provide robust and streamlined control of induction motors on machines and industrial utilities. It emphasises consistent parameterisation, embedded application logic and simplified maintenance. Drives in the range share a common architecture with a consistent functional base to reduce engineering and intervention time. The parameter library covers most standard cases, from basic speed setpoints to advanced ramp profiles and monitoring functions. Commissioning ergonomics rely on a local keypad and the manufacturer's software tools, reducing errors and speeding up restart after maintenance. Accessories enable adaptation of EMC performance and connectivity to existing infrastructure. Depending on size and power chosen, users select the configuration best suited to the motor and duty cycle while retaining the same operating logic across the family.

• Standard speed control: precise frequency adjustment for variable- or constant-torque loads, with expected energy savings on pumps and fans
• Integrated process functions: internal regulators, torque locks and alarm thresholds to secure the process without a complex external controller

The series is positioned for installations seeking a balance of performance, simplicity and availability, with a short learning curve for maintenance teams and smooth integration into existing automation architectures.

Industrial applications

The SKB1100110 drive is used in a variety of industrial environments where speed control optimises process performance and energy consumption. It integrates easily into PLC-sequenced control loops and meets the demands of continuous operation.

• Conveying and light handling: speed adjustment for belts, rollers and transfers to achieve synchronization and throughput
• Industrial pumping: setpoint adaptation according to flow and pressure, reducing hydraulic shocks
• Ventilation and air handling: fan control with V/f law, energy optimisation on variable-torque loads
• Assembly and packaging machines: speed control for repetitive operations and format changes
• Utility drives: auxiliary drives on production equipment where stability and availability are critical

Integration and communication

The DIGIDRIVE SK is wired into panels using standard cabling and can be controlled via local I/O or optional communication modules, depending on the automation architecture. Parameter setup is based on a logical menu structure, an operator keypad and the option to use the manufacturer's software tool for saving and duplicating configurations. Diagnostics are simplified by explicit fault codes and built-in monitoring functions, reducing mean time to repair.

Compatibility with industrial fieldbuses is provided via dedicated extensions, allowing setpoints and statuses to be exchanged with the PLC. This modular approach secures scalability, from simple local control up to integration in a machining cell or a multi-axis automated line. Ramp functions, current limits and electrical braking features help control mechanical and electrical transients while meeting machine and EMC constraints.
