f351 (Momentary acceleration (deceleration) suspend time) = (t1 + t2 + ts)
 Stall control
The inverter will automatically change the operation frequency when it detects an overcurrent, overload or
overvoltage. Configure each stall control setting using the following parameters.
Overcurrent stall :  (Stall prevention level 1)
Overload stall :  (Electronic thermal protection characteristic selection)
Overvoltage stall :  (Overvoltage limit operation)
Note: When the frequency command value, the acceleration suspend frequency (f350), and the deceleration
suspend frequency (f352) have the same setting, the acceleration/ deceleration suspend function will not
work.
