  • Page 342: Regeneration Avoidance Function

    14.9 Regeneration avoidance function The regenerative status can be detected and avoided by raising the frequency. • The operation frequency is automatically increased to prevent the regenerative operations. This function is useful when a load is forcibly rotated by another fan in the duct. Name Initial value Setting...

  • Page 344  Adjusting the regeneration avoidance operation (Pr.665, Pr.886) • If the frequency becomes unstable during regeneration avoidance operation, decrease the setting of Pr.886 Regeneration avoidance voltage gain. On the other hand, if an overvoltage fault occurs due to a sudden regeneration, increase the setting.

    14.10 Increased magnetic excitation deceleration Magnetic flux Magnetic flux Magnetic flux Increase the loss in the motor by increasing the magnetic flux during deceleration. The deceleration time can be reduced by suppressing the stall prevention (overvoltage) (oL). The deceleration time can be reduced without using a brake resistor. (When a brake resistor is used, the duty can be reduced.) Name Initial Setting...
