12.10 n: Special Adjustment
YASKAWA SIEPC71061737D GA800 Drive Technical Reference 1031
Note:
• It is not available with an SPM motor.
• The speed control range 1:100 is the momentary operation area. When you operate the motor continuously, make sure that the drive
capacity and motor capacity are acceptable.

Output Voltage Limit Level
Sets the output voltage limit to prevent saturation of the output voltage. Usually it is not necessary to
change this parameter.
200 V Class: 200.0 V,
400 V Class: 400.0 V
(200 V Class: 0.0 to 240.0 V,
400 V Class: 0.0 to 480.0 V)
Set this parameter lower than the input power supply voltage.
Note:
• When A1-02 = 7, 8 [Control Method Selection = CLV/PM, EZOLV], this parameter is available in Expert mode.
• When A1-02 = 8 [EZOLV], the default settings are:
–200 V Class: 230.0 V
–400 V Class: 460.0 V

Speed Fdbk Gain @ oV
Suppression
Sets the gain of internal speed feedback detection suppression while the overvoltage suppression
function is operating as a magnification value. Usually it is not necessary to change this parameter.
1.50
(0.00 - 10.00)
Adjust this parameter in these conditions:
• If there is resonance or hunting when you use the overvoltage suppression function, increase the setting value.
• If motor response is low when you use the overvoltage suppression function, decrease the setting value in 0.05-unit
increments.
■ n8-66: Output Voltage Limit Filter Time
