2.7 Types and Characteristics of Control Modes
The drive can select AM-V/F control (initial setting) and AM-open loop vector control.
Asynchronous motor V/F control
It means that when the frequency (F) is variable, the ratio of the control frequency to the voltage (V) remains constant.
This control mode is used for all variable speed control that does not require fast response and precise speed control, as well as the use of multiple
drives with one frequency drive. This method is also used when the motor parameters are not clear or cannot be self-tunned.
Asynchronous motor open loop vector control
The vector can be divided into the excitation current and the torque current by performing vector calculation on the output current of the drive, and
the frequency and voltage are compensated to flow the motor current matched with the load torque to improve the low speed torque. At the same
time, the output frequency compensation (slip compensation) is implemented to make the actual rotation speed of the motor closer to the speed
command value.
This control mode is used for applications requiring high speed control accuracy. High speed response and torque responsiveness, high torque
output at low speeds. Suitable for general high-performance control applications, one drive can only drive one motor.
Note：
For best control, enter the motor parameters correctly and perform motor self-tunning. The F02.0x group is the basic parameter group of the motor.
In the open loop control, the drive can only drive one motor; and the drive capacity and motor capacity can not be too different, the drive can be two
or smaller than the motor's power level, otherwise the control performance may be degraded. , or the drive system is not working properly.
