C5: ASR - SPEED REGULATION
The ASR adjusts the output frequency or torque reference to decrease the difference between frequency reference
and motor speed. The control method sets the parameter that you must adjust.
Control Method Targets of Adjustment
Closed Loop V/f Control (CL-V/f) Output frequency
•
Closed Loop Vector Control (CLV)
•
Advanced Open Loop Vector Control (AOLV)
•
Closed Loop Vector Control for PM (CLV/PM)

Note:
The detected speed is the speed estimation value when configured such that A1-02 = 4, 6, or 8 [Control Method = Adv OLVector, PM
AOLVector, or EZ Vector] .
