n8-41: HFI P Gain
No.
Name
(Hex.)
n8-41 HFI P Gain
(0568)
Expert
Note:
• Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-57 = 1 [HFI Overlap Selection = Enabled] to enable
this parameter.
• Set n8-41 > 0.0 for IPM motors.
Configure the setting as follows.
• Decrease the setting in units of 0.5 if an oscillation or hunting occurs.
• Increase the setting in units of 0.5 if tracking related to load changes is required.
■
n8-42: HFI I Time
No.
Name
(Hex.)
n8-42 HFI I Time
(0569)
Expert
Note:
Set n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection] or n8-57 = 1 [HFI Overlap Selection = Enabled] to enable
this parameter.
■
n8-45: Speed Feedback Detection Gain
No.
Name
(Hex.)
n8-45 Speed Feedback Detection
Gain
(0538)
Adjust this parameter in these conditions:
• If vibration or hunting occur, increase the setting value in 0.05 unit increments.
• If the responsiveness of torque and speed is unsatisfactory, decrease the setting value 0.05 unit increments and
examine the response.
■
n8-47: Pull-in Current Comp Filter Time
No.
Name
(Hex.)
n8-47 Pull-in Current Comp Filter
Time
(053A)
Adjust this parameter in these conditions:
• If the time for the reference value of the pull-in current to align with the target value is too long, increase the
setting value.
• If vibration or hunting occur, decrease the setting value in 0.2 unit increments.
• If the motor stalls during run at constant speed, decrease the setting value in 0.2 unit increments.
■
n8-48: Pull-in/Light Load Id Current
No.
Name
(Hex.)
n8-48 Pull-in/Light Load Id
Current
(053B)
RUN
Adjust in the following situations.
• Slightly reduce this value if there is too much current when driving a light load at a constant speed.
• Increase the setting value in steps of 5% when hunting or vibration occurs during run at constant speed.

V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the response gain for the high frequency injection speed estimation.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the integral time constant for the high frequency injection speed estimation. Usually it is not
necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the internal speed feedback detection reduction unit gain as a magnification value. Usually it
is not necessary to change this setting.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the time constant the drive uses to align the pull-in current reference value with the actual
current value. Usually it is not necessary to change this setting.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
On the basis that parameter E5-03 [Motor Rated Current (FLA)] is the 100% value, this
parameter sets the d-axis current that flows to the motor during run at constant speed as a
percentage.
