Description of Parameter Tables
This chapter details all of the parameters in the Quick Setting Menu (-QUICK-). Some parameters are not available for all
Control Methods. See Appendix A for details. Setting range and factory default value of the parameter follows the control
method table for each parameter.
Control Method
A1-02 Control Method Selection
The setting of parameter A1-02 determines which control method the Drive will use for operation. Select the control method
best suited for the application:
V/F Control is for general purpose and multiple motor applications.
V/F with PG Feedback is for general purpose applications requiring closed loop speed control.
Open Loop Vector is for applications requiring precise speed control, quick response, and higher torque at low speeds
(150% torque below 1Hz).
Flux Vector Control is for applications requiring very precise speed and torque control at a wide speed range including zero
speed. It requires encoder feedback.
Setting Description
0 V/F Control (factory default)
1 V/F with PG Feedback
2 Open Loop Vector
3 Flux Vector
