：
V/F Control
：
It is applicable to applications with low load requirements or applications
where one AC drive operates multiple motors, such as fan and pump.
1
：
Sensorless flux vector control (SFVC)
：
It indicates open-loop vector control, and is
applicable to high-performance control applications such as machine tool, centrifuge, wire
drawing machine and injection molding machine. One AC drive can operate only one motor.
2
：
Closed-loop vector control(CLVC)
：
It is applicable to high-accuracy speed control or
torque control applications such as high-speed paper making machine, crane and elevator.
One AC drive can operate only one motor. An encoder must be installed at the motor side,
and a PG card matching the encoder must be installed at the AC drive side.

：
Digital setting (non-retentive at power failure)
：
You can change the set frequency by
pressing ▲ ▲and▼on the operation panel. When the AC drive is powered on again after power
failure, the set frequency reverts to the value of P0.02 .

：
Digital setting (retentive at power failure)
：
You can change the set frequency by
pressing keys ▲ ▲and▼on the operation panel (or using the UP/DOWN functions of input
terminals) . When the AC drive is powered on again after power failure, the set frequency
is the value memorized at the moment of the last power failure.

：
CI analog setting (CI-GND). 0–10 V voltage input or 4–20 mA current input, determined
