Industrial Drives for Motor Control and Automation Systems

IEEE 519-2014 sets limits on voltage and current harmonic distortion injected into the power grid. A compliant drive, such as the H2 519/519P Series, ensures TDDi stays within 5% and THDv within 8%, preventing interference with sensitive equipment and avoiding penalties in municipal or utility-connected installations without requiring separate harmonic analysis.

The SW Series Washdown Drives are purpose-built for these conditions. They feature a UL Type 4X (IP66) polycarbonate enclosure that exceeds NEMA 1, 12, 4, and 4X standards, withstanding high-pressure washdown, moisture, and chemical exposure. A built-in power disconnect switch and safe torque off (STO) function further support safe operation in food and chemical processing plants.

Yes. Medium Voltage VFDs in the MVH2 and M2L Series are specifically engineered for MCC integration and retrofit projects with space constraints. Low voltage drives like the H2 Series support BACnet, Modbus-RTU, and Metasys-N2 protocols, enabling seamless integration into building automation and industrial control systems without major infrastructure changes.

Benshaw drives support a broad range of protocols depending on the model. The H2 Series offers RS-485 Modbus-RTU, BACnet, and Metasys-N2. The S Series adds Ethernet IP, Modbus TCP, and Profibus-DP. GM2 and SW Series drives include Modbus-RTU via RJ45 port, enabling connection to most industrial PLCs, SCADA systems, and building management platforms.

Selection depends on the motor's nameplate voltage, full-load amperage, load type (variable or constant torque), and environment. For HVAC and pumping, normal duty ratings are typically sufficient. Conveyor, mixer, and compressor loads often require heavy duty ratings. Contact a ValuAdd application engineer with your motor specifications and duty cycle for a precise recommendation.

Yes. The GM2 Series and S Series are specifically designed for OEM and panel builder environments. Both feature compact chassis designs with IP20 protection, DIN rail mounting (GM2 up to 7.5HP), and quick-setup preconfigured parameters. WinDRIVE PC-based commissioning software reduces setup time, and UL Listed open chassis ratings satisfy most panel certifications.
