Speed Control
Purpose
To limit the torque during speed
control
To adjust the speed control gain
To improve the motor trackability
for the speed command changes
To stabilize the speed detection
signal
To make starting torque start-up
faster
To avoid motor overrunning
This chapter explains the speed control under Real sensorless vector control, Vector control, and PM sensorless vector control.
Speed control performs control so that the speed command and the actual motor rotation speed match.
