Pm Sensorless Vector Control - Mitsubishi Electric FR-A820-00046 Instruction Manual

Speed control under Real sensorless vector control, vector control, PM sensorless vector control
5.3 Speed control under Real sensorless vector control, vector
control, PM sensorless vector control
Purpose
To limit the torque during speed
control
To adjust the gain for speed control
To improve the motor trackability for
the speed command changes
To stabilize the speed detection signal Speed detection filter
To make starting torque start-up faster Torque bias
To avoid motor overrunning
To avoid mechanical resonance
To adjust the gain during PM
sensorless vector control
Speed control performs control so that the speed command and the actual motor rotation speed
match.
