Frequently Asked Questions

• Q: What is the difference between "Heavy Duty" and "Super Heavy Duty" current ratings?
  A> "Heavy Duty" (32A) is for constant torque applications (e.g., conveyors, positive displacement pumps). "Super Heavy Duty" (24A) is for variable torque applications (e.g., centrifugal fans/pumps) where lower current is acceptable.
• Q: How do I use the built-in braking chopper?
  A> The chopper is ready to connect to an external dynamic braking resistor. You must select and install a properly sized resistor to dissipate the braking energy.
• Q: What does the "-21" suffix indicate?
  A> It typically denotes a specific hardware version or feature set. In this case, it often indicates a 460V input model with specific control options.
