12.8 n: Special Adjustment
346 YASKAWA SIEPYEULA5001C LA500 Technical Manual
Note:
• Set n2-02 ≤ n2-03. If n2-02 > n2-03, the drive will detect oPE08 [Parameter Selection Error].
◆ n6: Online Tuning
n6 parameters are used to set the online tuning function for motor line-to-line resistance.
The Online Tuning for motor line-to-line resistance is used to prevent degradation of speed control accuracy due
to motor temperature fluctuation and motor stalls due to insufficient torque.

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].
