0 : Disabled
1 : Line-to-line resistance tuning
The drive adjusts the motor line-to-line resistance during run. 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.
2 : VoltageAdjustm
The drive adjusts the output voltage during run to improve overload tolerance and minimize the effects of high
temperatures on speed accuracy.
Note:
Setting 2 is enabled only when b8-01 = 0 [Energy Saving Control Selection = Disabled].

Note:
• If oscillation occurs in the low speed range, either lengthen the acceleration time, or raise the setting value in 0.5 increments.
• To obtain starting torque by means of the setting for C4-01 [Torque Compensation Gain], reduce the setting value in 0.3 increments.

Note:
To improve tracking with respect to load changes, increase the setting value in increments of 5. If oscillation occurs during load changes
reduce the setting value in increments of 5.

V/f CL-V/f OLV CLV AOLV
Selects the type of motor data Online Tuning uses for OLV control.
V/f CL-V/f OLV CLV AOLV
Sets the compensation gain when set to n6-01 = 2 [Online Tuning Selection
= VoltageAdjustm]. Normally there is no need to configure this setting.
V/f CL-V/f OLV CLV AOLV
Adjusts the responsiveness for online resister tuning. To be enabled, the
value should be set to approximately 1.000. This is disabled if the value is
set to 0.
V/f CL-V/f OLV CLV AOLV
Sets the oscillation suppression gain for the low speed range.
V/f CL-V/f OLV CLV AOLV
Sets the response gain relative to load changes.
