This parameter specifies the compensation gain for disturbance torque. Increasing the gain may
improve the effect of suppressing disturbance impact but the noise may increase. This parameter
needs to be used with P2.43 to find the best setting point. After setting P2.43, increase the setting
of P2.42.

This parameter specifies the cut-off frequency of the disturbance observer. Decreasing the setting
of this parameter may decrease noise, while increasing the setting may decrease the disturbance
torque compensation delay. This parameter needs to be used with P2.42.
