Automatic Freq Regulator Time 2

Sets the time constant that sets the speed difference of the AFR function. Use this parameter for speed searches or regeneration. Usually it is not necessary to change this setting.

750 ms

(0 - 2000 ms)

Adjust this parameter in these conditions:

  • If the drive detects ov [Overvoltage] when acceleration stops under high-inertia loads, increase the setting value in 50 ms increments.

    If the drive detects ov when the load changes suddenly, increase the setting value in 50 ms increments.

  • To increase the responsiveness of torque and speed, decrease the setting value in 10 ms increments and examine the response.

Note:

  • Set n2-02 ≤ n2-03 [Automatic Freq Regulator Time 2]. If n2-02 > n2-03, the drive will detect oPE08 [Parameter Selection Error].

  • When you change the value in n2-03, also change the value in C4-06 [Motor 2 Torque Comp Delay Time] by the same ratio.
