Frequently Asked Questions

• Q: What is the main difference between VFD750V43A and VFD750V43C models?
  A> Both share the same core power ratings (100HP) and control features. The difference typically lies in the firmware version, specific default parameter sets, or minor hardware revisions. Always confirm the exact specifications for your application needs.
• Q: Can this drive operate a standard induction motor in closed-loop vector mode?
  A> Yes. For closed-loop vector control, an incremental encoder must be installed on the motor and connected to the drive to achieve the highest level of speed and torque precision.
• Q: What is required to implement dynamic braking?
  A> You must install an appropriately sized external dynamic braking resistor (DBR). The drive includes the necessary transistor circuitry, but the resistor is an optional accessory.
