C5: Auto Speed Regulator (ASR)

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.
A1-02 [Control Method Selection]
1: Closed Loop V/f Control (CL-V/f)
• 3: Closed Loop Vector Control (CLV)
• 4: Advanced Open Loop Vector Control (AOLV)
• 6: PM Advanced Open Loop Vector Control (AOLV/PM)
• 7: PM Closed Loop Vector Control (CLV/PM)
• 8: EZ Vector Control (EZOLV)
The speed control block diagrams of the respective control methods are shown in
