(0585)

Automatic Freq Regulator Time 1

Sets the time constant that sets the rate of change for the AFR function. Usually it is not necessary to change this setting.

50 ms

(0 - 2000 ms)

Adjust this parameter in these conditions:

  • If there is hunting or oscillation with a light load, increase the setting value in 50 ms increments and examine the response. If the load inertia is large, increase the setting value in 50 ms increments and examine the response.

  • If torque is not sufficient with a heavy load or if you must increase torque or speed responsiveness, 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 n2-02, also change the value in C4-02 [Torque Compensation Delay Time] by the same ratio.
