1 : Line-to-Line Resistance Tuning
The drive adjusts the motor line-to-line resistance during run. This procedure is applicable for speed values 6 Hz
and less. It also adjusts the motor resistance value to increase the overload capacity in the low speed range.
2 : Voltage Correction Tuning
The drive adjusts the output voltage during run to increase overload tolerance and minimize the effects of high
temperatures on speed precision.
Note:
Setting 2 is enabled only when b8-01 = 0 [Energy Saving Control Selection = Disabled].

When you use a motor that has a large secondary circuit time constant, decrease the setting value.
If the drive detects oL1 [Motor Overload], increase the setting value in 0.1-unit increments.

Note:
• If oscillation occurs in the low speed range, increase the acceleration time or increase the setting value in 0.5-unit increments.
• To get starting torque with the setting for C4-01 [Torque Compensation Gain], decrease the setting value in 0.3-unit increments.

V/f CL-V/f OLV CLV AOLV
Sets the type of motor data that Online Tuning uses for OLV control.
V/f CL-V/f OLV CLV AOLV
Sets the compensation gain when n6-01 = 2 [Online Tuning Selection =
Voltage Correction Tuning]. Usually it is not necessary to change this
setting.
V/f CL-V/f OLV CLV AOLV
Sets the responsiveness for online resistor tuning. Set this parameter to
approximately 1.000 to enable the function. The function is disabled when
the value is 0.000.
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 related to changes in the load.
