N8: Pm Motor Control Tuning - YASKAWA U1000 Technical Manual

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.

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.
n8-01
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.
n8-02
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.
n8-11
<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.

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.
n8-14
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.
n8-15
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.
