Frequently Asked Questions

• What is the difference between constant and variable torque ratings? Constant torque rating (31.7A) is for conveyors; variable torque (39.2A) is for centrifugal loads like pumps.
• How does the integrated dynamic braking benefit my application? The braking circuit allows faster stopping of high-inertia loads without mechanical wear on brakes.
• Can I control this drive remotely using a smartphone or tablet? Yes, connect to the built-in web server via Ethernet for monitoring and basic control from a browser.
• What size electrical enclosure do I need for this 20HP drive? Allow adequate space for cooling air circulation around all sides of the unit as specified in the manual.
• How do I select between V/Hz and Flux Vector Control modes? Use V/Hz for simple applications; choose FOC for precise speed control or high starting torque requirements.

This product includes a comprehensive twelve-month warranty for your complete peace of mind.
