FAQ

• Q: What are the main advantages of the C2000 series drive?
  A: The C2000 series, including the VFD550C43A-21, offers high-performance flux vector control for superior motor control accuracy. Key advantages include the built-in DC reactor for harmonic mitigation, a standard CANopen card for easy networking, and robust construction for industrial durability.
• Q: Can this drive handle both fan/pump and conveyor applications?
  A> Yes. The 110A Heavy Duty rating suits variable torque loads like fans and pumps. The 91A Super Heavy Duty rating is for constant torque applications like conveyors or mixers that demand higher starting torque and overload capacity, providing flexibility for various uses.
• Q: Is an external braking resistor needed?
  A> The drive does not have a built-in braking chopper. If your application involves frequent deceleration, high inertia loads, or overhauling loads (where the motor acts as a generator), you will need to install an external braking resistor and chopper module to safely dissipate the regenerative energy.
