Effective only for the inverter with built-in braking unit.
Due to the duty cycle of braking unit is adjusted, if the braking use rate is high, the duty
cycle of braking unit is high, the braking effect is stronger, but the inverter's bus voltage
fluctuation is larger during the braking process .

0: Linear acceleration and deceleration
The output frequency increases or decreases linearly. PI9000 provides four kinds of
acceleration and deceleration time. You can select by the multi-function digital input
terminals (F1.00 to F1.08).
1: S curve acceleration and deceleration A
The output frequency increases or decreases at the S curve. S-curve is used for the
