Sets a compensation gain to improve the control qualities for motoring loads in the low
speed range.

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.
