Variable frequency drive overview

The variable frequency drive adopts current vector arithmetic, precise control. Offer customers added value application functions and supply the specific solution projects for them individually.variable frequency drive overview

VFD features:
  1. V/F control and no-speed vector control.
  2. Start torque could be 150% when it is 2Hz.
  3. Main frequency superposes with auxiliary frequency.
  4. AVI/ACI setting, RS485 communication, impulse input frequency control (selective).
  5. Interior installed PLC could run under 16 sections of programs.
  6. 3 sections of forbidden frequency could prevent resonance.
  7. The manipulator could be expanded.
  8. Wobble frequency function.
  9. The VFD has PID feedback control.
  10. Braking is controlled by software, available to adjust braking limitation and braking use rates.
  11. Hardware links with software filter, which produces better anti-interference effects.
  12. Overvoltage, overcurrent, low voltage, overload limitation, overload and overheat protection functions, etc.
