n
n6-05: Online Tuning Gain
Sets the compensation gain for the voltage correction in the Online Tuning function (n6-01 = 2).
Although this parameter rarely needs to be changed, increase the set value in steps of 0.1 if an overload fault occurs during
voltage correction
No. Name Setting Range Default
n6-05 Online Tuning Gain 0.1 to 50.0 1.0
u
n8: PM Motor Control Tuning
These parameters adjust the control performance in the vector control modes for permanent magnet motors.
n
n8-01: Initial Rotor Position Estimation Current
Sets the current used for initial rotor position estimation as a percentage of the motor rated current (E5-03). If the motor
nameplate lists an “Si” value, that value should be entered here. There is normally no need to change this parameter from the
default value.
Note: This parameter is only available in AOLV/PM or CLV/PM.
No. Name Setting Range Default
n8-01 Initial Rotor Position Estimation Current 0 to 100% 50%
n
n8-02: Pole Attraction Current
In AOLV/PM control, this parameter sets the current to attract the rotor after detecting the initial rotor position. The value is
set as a percentage of the motor rated current. Increase this setting to increase the starting torque.
In CLV/PM control, this parameter sets the current used to detect the rotor pole when tuning the phase-Z pulse position. Set
this parameter to a large value if the motor does not follow the target position during the phase-Z pulse position tuning. Set
to a small value if the motor vibrates. There is normally no need to change this parameter from the default value.
No. Name Setting Range Default
n8-02 Pole Attraction Current 0 to 150% 80%
n
n8-11: Induction Voltage Estimation Gain 2
Sets the gain for speed estimation. There is normally no need to change this parameter from the default value.
No. Name Setting Range Default
n8-11 Induction Voltage Estimation Gain 2 0.0 to 1000.0
Determined by
n8-72
<1>
<1> When n8-72 is set to 0, the default setting is 50.0 and when n8-72 is set to 1, the default setting is 150.0. Refer to n8-14: Polarity Compensation
Gain 3 on page 339 for a list of monitors.
n
n8-14: Polarity Compensation Gain 3
Sets the gain for speed estimation. There is normally no need to change this parameter from the default value.
No. Name Setting Range Default
n8-14 Polarity Compensation Gain 3 0.000 to 10.000 1.000
n
n8-15: Polarity Compensation Gain 4
Sets the gain for speed estimation. There is normally no need to change this parameter from the default value.
No. Name Setting Range Default
n8-15 Polarity Compensation Gain 4 0.000 to 10.000 0.500
n
n8-21: Motor Ke Gain
Sets the gain for speed estimation. There is normally no need to change this parameter from the default value.
No. Name Setting Range Default
n8-21 Motor Ke Gain 0.80 to 1.00 0.90
