n8-37: High Freq Injection Amplitude
No.
Name
(Hex.)
n8-37 High Freq Injection
Amplitude
(0564)
This parameter is enabled when n8-57 = 1 [High Frequency Injection = Enabled] is set. Set automatically when
Stationary Auto-Tuning or Rotational Auto-Tuning is carried out.
Note:
When changes are made to C6-02 [Carrier Frequency Selection], the setting for n8-37 is automatically initialized. After selecting the
carrier frequency to be used, perform Auto-Tuning.
■
n8-41: HFI Overlap Pole Detection Pgain
No.
Name
(Hex.)
n8-41 HFI Overlap Pole
Detection Pgain
(0568)
Note:
Effective when n8-57 = 1 [High Frequency Injection = Enabled] or n8-35 = 1 [InitRotorPosition Detect Select = High frequency
injection].
■
n8-42: HFI Overlap Pole Detection iTime
No.
Name
(Hex.)
n8-42 HFI Overlap Pole
Detection iTime
(0569)
Note:
Effective when n8-57 = 1 [High Frequency Injection = Enabled] or n8-35 = 1 [InitRotorPosition Detect Select = High frequency
injection].
■
n8-45: Spd Feedback Detect Control Gain
No.
Name
(Hex.)
n8-45 Spd Feedback Detect
Control Gain
(0538)
Adjust in the following situations.
• Increase the setting value in steps of 0.05 when vibration or hunting occurs.
• Decrease the setting value in steps of 0.05 while checking response when the responsiveness of torque and
speed is poor.
■
n8-47: Pull-InCurCompensationTime Const
No.
Name
(Hex.)
n8-47 Pull-
InCurCompensation
(053A)
Time Const
Adjust in the following situations.
• Increase the setting when it takes too long for the reference value of the pull-in current to match the target value.
• Decrease this setting value in steps of 0.2 if hunting or vibration occur.
• Decrease the setting value in steps of 0.2 if the motor stalls during run at constant speed.

V/f CL-V/f OLV CLV AOLV
Considering 200 V to be the 100% value with a 200 V class unit, and 400 V
to be 100% with a 400 V class unit, set the high frequency injection
amplitude as a percentage value. Normally there is no need to change this
setting.
V/f CL-V/f OLV CLV AOLV
Sets the speed estimation response for high frequency injection. Normally
there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the oscillation suppression gain of the speed estimation for high
frequency injection. Normally there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the internal speed feedback detection reduction unit gain as a
magnification value. Normally there is no need to change this setting.
V/f CL-V/f OLV CLV AOLV
Sets the time constant used to match the pull-in current reference value with
the actual current value. Normally there is no need to change this setting.
