Note:
•
If response to the speed reference is slow, increase the value set in n5-03 .
• Increase the value set in n5-03 when response to the speed reference is slow.
– The speed is overshooting.
– A negative torque reference is output when acceleration ends.

Speed Response Frequency
Sets the response frequency for the speed reference. Usually it is not necessary to change this
parameter.
Determined by A1-02
(0.00 - 500.00 Hz)
If you set n5-03 [Feed Forward Control Gain] too high, the motor speed will momentarily increase to more than the
set frequency.
◆
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.

0 : Disabled
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] .

Usually it is not necessary to change this parameter.
1.0
(0.1 - 50.0)
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.

Online Resistance Tuning
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 .
