C7-12
(26EH)
Reactive Current
Reference Bias
Automatic
Calculation
Selection
React I Bias Sel
There is normally no need to change this parameter from
the default value. Sets whether to automatically calculate
the leading current compensation for the control process to
compensate the leading current in the reactive current
reference so that the leading current becomes 0.
0: Disabled
1: Enable (Automatically calculate the reactive current
reference bias.)
Default: 1
Range: 0, 1
C7-41
(1128H)
Gain for Active
Damping 2
Damp Gain 2
There is normally no need to change this parameter from
the default value.
Default: 0.000
Min.: 0.000
Max.: 10.000
C7-42
(1129H)
Gain for Automatic
Compensation of
Leading Current
Id Bias Gain
There is normally no need to change this parameter from
the default value.
It is used to make fine adjustments to the power factor.
Default: 100.0%
Min.: 0.0%
Max.: 1000.0%
C7-43
(112AH)
Input Voltage Offset
Adjustment
Vac Bias Adj Sel
There is normally no need to change this parameter from
the default value. This parameter is for factory setting.
If the setting is not correct, the converter may be damaged.
0: Standard
1: Start offset adjustment. (The parameter returns to 0 after
it is set.)
2: Offset adjustment not required. (The parameter returns
to 0 after it is set.)
Default: 0
Range: 0 to 2
