0: open-loop flux vector control: refers to that the open-loop flux vector control is
suitable for high-performance general-purpose applications where the encoder PG is
not installed, an inverter can only drive one motor. Such as machine tools, centrifuges,
wire drawing machines, injection molding machines and other loads. The capacity of
frequency inverter and motor should not differ much, frequency inverter capacity can
be 2 size bigger or 1 size smaller than motor capacity, otherwise may lead to control
performance degradation, or the un-normal operation of drive system.
1: Reserved
2: V/F control: suitable for applications that demanding less control accuracy,
such as fans, pumps and other loads. It can used for occasions that one inverter drives
multiple motors.
3: Torque control: suitable for applications that demanding less torque control
accuracy, such as wound, drawing and other occasions. In torque control mode, the
motor speed is determined by the motor load, its acceleration and deceleration speed is
no longer determined by the inverter deceleration time.
Note: open-loop flux vector control and torque control must perform motor auto
tunning firstly.

Select the inverter frequency command input channels, there are eight kinds of
given frequency channels:
0: Keyboard setting: to achieve by modifying function code F0.01 "keyboard set
frequency" value.
1: Analog AI1 setting
2: Analog AI2 setting
3: Panel potentiometer setting
Refers to that the frequency is determined by the analog input terminals, CA
SERIES inverter is equipped with standard two-way analog input terminals (AI1, AI2),
AI1/AI2 voltage and current optional (0V to 10V/0mA to 20mA), it can be switched
by the jumpers JP2 and JP3 on control panel. The corresponding relationship between
AI1, AI2 input voltage value and the target frequency can be set through F1 function
