YASKAWA GA700 Technical Manual page 875

Note:
With a setting of n1-05 = 0, the value set in n1-02 [Hunting Prevention Gain Setting] will be effective even when the motor rotates in
reverse.
Adjust this parameter in the following circumstances.
• With settings of n1-01 = 1, 2 [Hunting Prevention Selection = Enabled, Enable (High carry)]: If oscillation
occurs when operating a motor with a light load, increase the setting value in increments of 0.1.
• With settings of n1-01 = 1, 2, if the motor stalls: Reduce the setting value in increments of 0.1.

n1-08: Leak cur antivib
No.
Name
(Hex.)
n1-08 Leak cur antivib
(1105)
0 : Method1
1 : Method2
Note:
The n1-08 = 1 setting is effective in suppressing motor vibrations due to leakage current when the wiring distance is long.
■
n1-13: DC Bus Stabilization Control
No.
Name
(Hex.)
n1-13 DC Bus Stabilization
Control
(1B59)
0 : Disabled
1 : Enabled
Note:
Set n1-13 = 1 when the DC bus voltage does not stabilize with light loads and ov [Overvoltage] is detected.
■
n1-14: DC Bus Stabilization Time
No.
Name
(Hex.)
n1-14 DC Bus Stabilization
Time
(1B5A)
Note:
To adjust, increase n1-14 in increments of 100 ms.
■
n1-15: Voltage Calibration Select
No.
Name
(Hex.)
n1-15 Voltage Calibration
Select
(0BF8)
This calibration function allows for the suppression of a motor's torque ripple. Normally there is no need to
change this setting.
0 : Calibration Invalid
1 : Calibrate only 1 time
2 : Calibrate every time

V/f CL-V/f OLV CLV AOLV
Selects the method of suppressing motor vibration caused by leakage
current. Normally there is no need to configure this setting.
V/f CL-V/f OLV CLV AOLV
Enables or disables the oscillation suppression function for the DC bus
voltage.
V/f CL-V/f OLV CLV AOLV
With a setting of n1-13 = 1 [DC Bus Stabilization Control = Enabled],
adjustments that address a lack of oscillation suppression capability with
respect to the DC bus voltage can be made.
V/f CL-V/f OLV CLV AOLV
Selects the calibration method to be used for the suppression of torque/
current ripple.
