(14) Settings of stall prevention
A.
F_070
: Level of stall prevention during acceleration with range
30~200% of rated current of inverter.
B.
F_071
: Level of stall prevention at the constant speed with range
30~200% of rated current of inverter.
C.
F_072
: Acceleration time of recovery after stall prevention at the
constant speed with range 0.1~3200.0 seconds.
D.
F_073
: Deceleration time of recovery after stall prevention at
the Constant speed with range 0.1~3200.0 seconds.
E.
F_074
: Select function of stall prevention during deceleration.
0 : There is no stall prevention during deceleration
1 : There is stall prevention during deceleration.
a. The function of stall prevent is shown in the timing chart:
Note:
b.
The function of stall prevention during deceleration is to
maintain a constant speed in the stall condition.
c. If the dynamic braking device is installed, the F_074 function of
stall prevention during deceleration may be disabled.
d.
When the inverter is stop and the DC bus voltage is higher than
the DC braking level, the display show the db.(the RUN key is
useless now); when the DC bus voltage is lower than the DC
braking level, recover to the main display automatically.
