C7: Voltage Adjustment

n C7-43: Input Voltage Offset Adjustment
Note: Adjustment is completed at the factory. Do not change the setting of this parameter.
Enables adjustment of the offset for the input voltage circuit when the control board is replaced.
Changing the value of o2-04 will trigger an oPE30 error. The input voltage offset must be adjusted when the error occurs. If
the combination of the control board and drive does not change, set this parameter to 0002 (offset adjustment not required).
Contact Yaskawa or a Yaskawa representative if it becomes necessary to replace the control board.
No.
C7-43
Setting 0000: Standard
Setting 0002: Offset Adjustment Not Required
n C7-56: Power Factor Control Selection
Power factor control improves the input power supply power factor according to the operating conditions.
This parameter rarely requires adjustment, but may be enabled to improve the power factor in the low output region. Power
factor control is not suitable for applications with frequent load fluctuations.
This function is disabled in High Output Voltage Mode (C7-60 = 1).
No.
C7-56
Setting 0: Power Factor Control Disabled
Setting 1: Power Factor Control Enabled
n C7-60: Output Voltage Limit Mode Selection
Sets the mode to limit the output voltage.
Set this parameter to 0 (Harmonic suppression priority mode) to give priority to harmonic suppression. The maximum output
voltage is automatically limited to suppress harmonics.
Set this parameter to 1 (High output voltage mode) to give priority to the output voltage over harmonic suppression. The
effectiveness of harmonic suppression will be reduced because the maximum output voltage will be used.
No.
C7-60
Setting 0: Harmonic Suppression Priority Mode
Setting 1: High Output Voltage Mode
