n4-61
(1B81)
Low Speed Comp Frequency Level
Sets a frequency at which the settings n4-60 [Motoring Low Speed Comp Gain] and n4-62 [Regen Low Speed Comp Gain] are enabled. When the output frequency < n4-61, the drive adjusts the torque to agree with the settings for n4-60 and n4-62. Usually it is not necessary to change this setting.
6.00 Hz
(0.50 - 12.00 Hz)
n4-62
(1B82)
Regen Low Speed Comp Gain
Sets a compensation gain to improve the control qualities for regenerative loads in the low speed range.
(50.0 - 500.0%)
n4-63
(1B83)
Speed EstimateResponse@High Freq
Sets the responsiveness of the speed estimation in high speed ranges, where the output frequency is ≥ n4-67 [Estimate Gain Switchover Freq].
60.0
(0.1 - 300.0)
n4-64
(1B84)
Speed Estimate Response@Low Freq
Sets the responsiveness of the speed estimation in low speed ranges, where 0 ≤ the output frequency, which is < n4-67 [Estimate Gain Switchover Freq].
n4-65
(1B85)
Flux Estimate Response@High Freq
Sets the responsiveness of the magnetic flux estimation in high speed ranges, where the output frequency is ≥ n4-67 [Estimate Gain Switchover Freq]. Usually it is not necessary to change this setting.
1.00
(0.50 - 3.00)
n4-66
(1B86)
Flux Estimate Response @Low Freq
Sets the responsiveness of the magnetic flux estimation in low speed ranges, where 0 ≤ the output frequency, which is < n4-67 [Estimate Gain Switchover Freq]. Usually it is not necessary to change this setting.
