Unit digit:
0 (set to save the frequency at power failure): When the drive is powered down or
undervoltage, F1.07 automatically refreshes at the current frequency set value.
0 (set not to save the frequency at power failure): When the drive is powered down or
undervoltage, F1.07 keeps unchanged.
Ten digit:
0 (set to maintain the frequency at shutdown): When the drive is shut down, the
frequency set value is the final modified value.
1 (set to restore frequency to F1.07 at shutdown): When the drive is shut down,
system automatically restores the frequency set value to F1.07.

Max. output frequency
F1.09~550.00Hz
50.00Hz
The maximum output frequency is the highest frequency allowed by the drive, as
shown in fmax in Figure 6-1.
The F3.04 basic operating frequency is the minimum frequency when the drive outputs
the highest voltage, which is usually the rated frequency of the motor. As shown in fb in
Table 6-1.
When the maximum output voltage of F3.05 is the basic operating frequency of the
drive, the corresponding output voltage is usually the rated voltage of the motor, as shown
in Vmax in Figure 6-1.
Figure 6-1 Voltage and Frequency Schematic Diagram
fH and fL are defined as upper limit frequency and lower limit frequency respectively in
F1.09 and F1.10.
Note: Be sure to set
f
max,
f
b, and
V
max, according to the motor parameters,
otherwise the equipment may be damaged.
