12.10 n: Special Adjustment
1022 YASKAWA SIEPC71061737D GA800 Drive Technical Reference
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.
0.000
(0.000 - 1.000)
◆ n7: EZ Drive
The n7 parameters provide special adjustments for EZ Vector Control.

Damping Gain for Low
Frequency
Sets the oscillation suppression gain for the low speed range.
1.0
(0.1 - 10.0)
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.

Response Gain for Load
Changes
Sets the response gain related to changes in the load.
100
(10 - 1000)
Note:
To make tracking related to load changes better, increase the setting value in 5-unit increments. If oscillation occurs during load changes,
decrease the setting value in 5-unit increments.

Speed Calculation Gain1
Sets the speed calculation gain during usual operation. Usually it is not necessary to change this
setting.
15.0
(1.0 - 50.0)
■ n7-08: Speed Calculation Gain2
No.

Speed Calculation Gain2
Sets the speed calculation gain during a speed search.
25.0
(1.0 - 50.0)
Note:
When you increase the setting value, you can do a speed search of a motor rotating at a high frequency. If the setting value is too high, the
calculated speed will oscillate and a restart will fail. Decrease the setting value in these conditions.
