The Schneider Electric VW3A7101 is a resistance braking unit designed to supplement the braking capabilities of variable speed drive systems. This accessory is engineered for compatibility with the Schneider Electric Altivar 61, Altivar 71, Altivar 61Q, Altivar 71Q, and Altivar Process ATV900 series variable speed drives. It provides a method for dissipating excess energy generated during deceleration, thereby improving system control and protecting drive components.

Technical details

• Series Compatibility: Altivar 61, Altivar 71, Altivar 61Q, Altivar 71Q, Altivar Process ATV900
• Functionality: Resistance braking unit for energy dissipation during deceleration
• Purpose: Enhances braking performance and system stability
• Application: Designed to work in conjunction with compatible variable speed drives
• Energy Dissipation: Utilizes a braking resistor (sold separately or integrated) to convert kinetic energy into heat
• Control: Integrates with the drive's control logic for seamless operation
• Protection: Helps prevent overvoltage faults during rapid deceleration

Applications & compatibility

This braking unit is essential for applications involving frequent starts and stops, or where significant inertia requires controlled deceleration. Common uses include packaging machinery, material handling systems, conveyor belts, and any industrial process where precise speed control and effective braking are critical for operational efficiency and safety.
