n8-39
(0566)
PM Phase Compensation
Gain
Sets the low-pass filter shut-off frequency for high frequency injection.
250 Hz
(0 - 1000 Hz)
Note:
•
Set
n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection]
or
n8-57 = 1 [HFI Overlap Selection = Enabled]
to enable this
parameter.
•
The drive automatically calculates this value when High Frequency Injection Auto-Tuning completes successfully.

HFI P Gain
Sets the response gain for the high frequency injection speed estimation.
2.5
(-10.0 - +10.0)
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.

HFI I Time
Sets the integral time constant for the high frequency injection speed estimation. Usually it is not
necessary to change this setting.
0.10 s
(0.00 - 9.99 s)
Note:
Set
n8-35 = 1 [Initial Pole Detection Method = High Frequency Injection]
or

Speed Feedback Detection
Gain
Sets the internal speed feedback detection reduction unit gain as a magnification value. Usually it is
not necessary to change this setting.
0.80
(0.00 - 10.00)
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.

PM Phase Compensation
Gain
Sets the gain to compensate for phase differences. Usually it is not necessary to change this setting.

(0.0 - 10.0)
If there is vibration in the motor, increase the value. When you must detect
oC [Overcurrent]
or
ov [DC Bus
Overvoltage]
, set this parameter to a low value.
