Figure 6-21 Overvoltage Stall Mode 1
In deceleration process, after DC bus voltage exceeds overvoltage stall voltage (F07.06),
inverter stops deceleration process, and remains at present running frequency. After DC bus
voltage decreases, inverter will decelerate as per previous deceleration time, see Figure
6-21.
F07.05=2 Overvoltage Stall Mode 2
Overvoltage stall mode 2 is applied to the applications which are sensitive to acceleration/
deceleration time.
In this mode, the motor frequency is automatically adjusted by DC bus voltage as per the PI
parameters set in F07.07 and F07.08.
For load with larger inertia if overvoltage stall occurs during deceleration, the propotional
gain may be increased.
For load with smaller inertia, the propotional gain may be kept smaller.
Integral time can be adjusted for fine tunning in both cases.
