the drive.
1: Terminal control: Input operating commands
via terminals
Use terminals FWD, REV, to start and stop the
drive.
2: Serial port control: Input operating commands
via serial port
Use serial port to start and stop the drive.
Note：
Note that during operating process, the control modes
can be changed by changing the setting of F0.03. Be
careful if you want to do so.
F0.04 Running Direction
The function applies to keypad control and serial
port control, but not terminal control mode.

The max. frequency refers to the allowed max.
output frequency of the drive. Refer to the f
Fig. 5-2;
Base frequency normally corresponds with the
rated frequency of the motor. It is the Min
frequency when the drive outputs the highest
voltage, as shown in Fig. 5-2 as f
Max output voltage is the drive's output voltage
when the drive outputs base frequency, as shown
in Fig. 5-2 as V

Note：
Please set fmax, fb and Vmax according to motor
parameters on its nameplate. Failing to do so may
damage the motor.
F0.08 Reserved
F0.09 Torque boost
In order to compensate the torque drop at low
frequency, the drive can boost the voltage so as
to increase the torque. If F0.09 is set to 0, auto
torque boost is enabled and if set at non-zero,
manual torque boost is enabled, as shown in Fig.
5-3.
