A1-02: Control Method Selection

Sets the control method for the drive application and the motor.

0

V/f Control

Use this control method in these applications and conditions:

• For general variable-speed control applications in which a high level of responsiveness or high-precision speed control is not necessary.

• Applications in which more than one motor are connected to one drive

• When there is not sufficient data to set the motor parameters

• When it is not possible to do Auto-Tuning. The speed control range is 1:40.

2

Open Loop Vector

Use this control method for general variable-speed control applications in which high-precision speed control is necessary. In this control method, a feedback signal from the motor is not necessary to have high torque response and high torque when operating at low speeds. The speed control range is 1:100.

5

PM Open Loop Vector

The drive controls an IPM motor or SPM motor in this control method. Use this control method for general variable-speed control applications in which a high level of responsiveness or high-precision speed control are not necessary. The speed control range is 1:10.

6

PM Advanced Open Loop Vector

The drive can control an IPM motor in this control method. Use this control method for general variable-speed control applications in which high-precision speed control and torque limit are necessary. The speed control range is 1:20. The speed control range is 1:10 when n8-57 = 1 [HFI Overlap Selection = Enabled].

8

EZ Vector Control

The drive controls induction motors and PM motors in this control method. This control method uses an easier procedure to operate motors with more efficiency. Use this control method for derating torque applications. For example, fans and pumps.
