Chapter 12 Description of Parameter SettingsC2000-HS
12.1-10-12
This parameter is only valid under PM sensorless speed mode (Pr.00-11=6).
Increase the setting for this parameter to enhance the loading performance at START.
The low-speed area includes motor’s 1/5 rated rotor speed and below; the high-speed area
includes the motor’s 1/5 rated rotor speed and above.
Magnetic Linkage Estimator High-speed Gain
Default: 100%
Settings 10–1000%
This parameter is only valid under PM sensorless speed mode (Pr.00-11=6).
Increase the setting for this parameter to enhance the loading performance at high-speed area,
and improve the response of magnetic linkage estimator.
When a speed vibration occurs in the week magnet area, decrease the setting for this
parameter.
Phase Locked Loop (PLL) Kp
Default: 100%
Settings 10–1000%
Increase the setting for this parameter to enhance the loading performance at high-speed area,
and improve the response of magnetic linkage estimator.
When a high-frequency fluctuation occurs to the speed output frequency, decrease the setting
for this parameter.
Phase Locked Loop (PLL) Ki
Default: 100%
Settings 10–1000%
Increase this parameter to enhance the speed response during acceleration and deceleration.
