5.9 n: Special Adjustments
■ n5-07: Speed Feedback Compensation Selection
Enables or disables the Speed Feedback Compensation.
Enabling the Speed Feedback Compensation can help stop motor oscillation that results from setting the ASR
proportional gain (C5-01) to a high value for faster speed response.

■ n5-08: Speed Feedback Compensation Gain (P)
Sets the proportional gain for the Speed Feedback Compensation.
Although this parameter rarely requires adjustment, increasing the gain can help improve responsiveness relative to the
load. Lower setting if oscillation occurs.

Setting 1: Line-to-line resistance tuning
This setting enables line-to-line resistance online tuning. This procedure is effective for speed values up to 6 Hz and
improves the overload capacity in the low speed range by adjusting the value set for the motor resistance.
Setting 2: Voltage correction
The drive adjusts the output voltage during run to improve overload tolerance and minimize the effects of high
temperatures on speed accuracy.
Note:
This setting can only be selected i f the Energy Saving function is disabled (b8-01 = 0).
■ n6-05: Online Tuning Gain
Sets the compensation gain for the voltage correction in the Online Tuning function (n6-01 = 2). Although this parameter
rarely needs to be changed, increase the set value in steps of 0.1 if an overload fault occurs during voltage correction.
