During inverter deceleration, the motor shall produce rebound energy into inverter under the 
influence of load inertia to make the voltage on inverter DC side rise; while overvoltage stall 
function is started and inverter DC voltage is overhigh, the inverter shall stop decelerating till 
DC side voltage is lower than set value, and for the inverter is decelerating, deceleration time 
shall automatically prolong.

During inverter acceleration, output current of the inverter shall rise rapidly due to overload or 
excessively short acceleration time, and the inverter shall stop accelerating while exceeding 
rated  set  level;  when  the  current  is  lower  than  set  value,  the  inverter  shall  continue 
accelerating. 

[Note] 100% current refers to rated current of the motor, and when the parameter is set 
to 0, stall prevention function is invalid during acceleration.

During  constant  running  of  variable  frequency  accelerator,  the  current  increases  due  to 
fluctuation  of  load  or  other  reason;  when  the  current  exceeds  rated  set  value,  the  inverter 
shall  decrease  output  frequency,  and  if  output  current  returns  to  normal,  the  inverter  shall

When the inverter is applied to the load of fans and pumps, P120 can be set as 120%; when 
the current of inverter is greater than 120%, output frequency shall decrease, consequently 
the current shall decrease; however, after the current returns to normal, the frequency also 
shall become normal gradually, thus achieving stall prevention function; decrease rate of the 
frequency depends on P121.
