C5: Automatic Speed Regulator (ASR: Automatic Speed Regulator)

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 (AOLV/PM)
• 7: Closed Loop Vector Control for PM (CLV/PM)
• 8: EZ Vector Control (EZOLV)
