11 Drive Control and Programming
◆ Selecting the Control Method
This section gives information about these basic control methods:
• V/f Control
• 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.
Use A1-02 [Control Method Selection] to select the most applicable control method for your application.
Control Method A1-02 Setting Main Applications
V/f 0
• General variable-speed. Best method to operate more than one motor from one drive.
• When motor parameters are not available.
EZOLV 8
• General variable-speed
• No high precision, no high speed response, and no speed feedback
◆ Auto-Tuning
WARNING
Injury to Personnel. Rotational Auto-Tuning rotates the motor at 50% or more of the motor rated frequency. Make
sure that there are no issues related to safety in the area around the drive and motor. Increased motor frequency can cause serious
injury or death.
WARNING
Sudden Movement Hazard. Before you do Rotational Auto-Tuning, disconnect the load from the motor. The load
can move suddenly and cause serious injury or death.
Auto-Tuning automatically sets parameters on the drive connected to the motor. You must input some parameters
individually during Auto-Tuning.
1. Select [Auto-Tuning] from the main menu to select the Auto-Tuning Mode.
2. Use the information in Table 11.1 and Table 11.2 to set T1-01 [Auto-Tuning Mode Selection] and T4-01 [EZ
Tuning Mode Selection].
3. Push to start Auto-Tuning.
Refer to the Technical Reference for more information about Auto-Tuning.
