◆ Selecting the Control Method
This section gives information about these basic control methods:
• V/f Control (V/f)
• Open Loop Vector Control (OLV)
• EZ Open Loop Vector Control (EZOLV) for induction motors only
Refer to the Technical Reference for information about speed feedback and Permanent Magnet/Synchronous
Reluctance motor control methods.
Set the most applicable control method for your application. A1-02 [Control Method Selection] sets the drive
operation.
