6. Set up the speed estimator related parameters
I/F Mode Current Command / Low-speed Current Command under PMSVC
Control
Factory
Setting:40
Settings 0~150% of motor’s rated current
The parameter is the current command of the drive in low-speed area (low-speed area:
frequency command < Pr10-39).
When it is stalling on heavy duty start-up or forward/reverse with load, adjust the parameter
(to increase it). If inrush current too higher to cause oc stall, then decrease it.
PM FOC Sensorless Speed Estimator Bandwidth
Factory Setting: 5.00
Settings 0.00~600.00Hz
The parameter is speed estimator bandwidth. Adjust the parameter will influence the stability
and the accuracy of speed for motor.
If there is low frequency vibrates (the waveform is similar to sine wave) during the process,
then increase the bandwidth. If there is high frequency vibrates (the waveform vibrates
extremely and is like spur), then decrease the bandwidth.
PM Sensorless Observer Low-pass Filter Gain
Factory Setting: 1.00
Settings 0.00~655.35
Adjust the parameter will influence the speed estimator’s speed of response.
If there is low frequency vibrates (the waveform is similar to sine wave) during the process,
then increase the gain. If there is high frequency vibrates (the waveform vibrates extremely
and is like spur), then decrease the gain.
AMR (Kp)
Factory Setting: 1.00
Settings 0.00~3.00
AMR (Ki)
Factory Setting: 0.20
Settings 0.00~3.00
Active Magnetic regulator--- Kp and Ki. These two parameters will influence magnetic flux
control of field weakening region.
Increase the parameter if the input power has rapid change (ex. unstable electrical grid
makes voltage be insufficient in a sudden) while enter the field weakening region, and ACR
diverges to cause oc (ex. during the application of Press, there are other Press is working,
and DC BUS decreases extremely in a sudden). If Id has spur and cause high frequency
noise of output current to be too big, then decrease the parameter to lower the noise, but
this also might cause a slow response.
