Speed Control By Real Sensorless Vector Control, Vector Control - Mitsubishi Electric FR-A700 Instruction Manual

Speed control by real sensorless vector control, vector control

6.3 Speed control by real sensorless vector control, vector
control
Speed control is exercised to match the speed command and actual motor speed.
Purpose
To perform torque limit during speed
control
Gain adjustment of speed control
To enhance the trackability of the
motor in response to a speed com-
mand change
Stabilize the speed detection signal
Accelerates the rise of the torque at
a start
Avoid mechanical resonance
