0: forward
When this mode is selected, the actual output phase sequence of the inverter is consistent with the system default phase sequence. At this time, the functions of
the keys
RUN
on the panel and the FWD terminal become forward rotation control.
1: Reverse
When this mode is selected, the actual output phase sequence of the inverter will be opposite to the system default phase sequence. At this time, the functions of
the keys
RUN
on the panel and the FWD terminal become reverse control.
2: Reversal is prohibited
In any case, the motor can only run forward. This function is suitable for occasions where reverse operation may bring danger or property damage. Given a reverse
command, the inverter runs at zero speed.

This group of function codes defines the setting mode of the motor's V/F curve to meet the requirements of different load characteristics. According to the definition of
00.13, fixed curves and a custom curve can be selected.
0: linear curve
The linear curve is suitable for ordinary constant torque load, and the output voltage has a linear relationship with the output frequency.
1: Square curve
The square curve is suitable for square torque loads such as fans and water pumps to achieve the best energy saving effect. The output voltage and the output
frequency have a square curve relationship.
2: Multi-point V/F curve (determined by 00.17
～
00.22)
When 00.13 selects 2, the user can customize the V/F curve through 00.17
～
00.22, and define the V/F curve by adding (V1, 01), (V2, F2), (V3, F3), and the origin and
maximum frequency points. F curve is suitable for special load characteristics.

In order to compensate for the low-frequency torque characteristics, some boost compensation can be made to the output voltage. When this function code is set to
0.0%, it is automatic torque boost. When it is set to any value other than 0.0%, it is manual torque boost mode. 00.15 defines the boost cut-off frequency point fz during
manual torque boost, as shown in Figure 00 -4 shown.
