Over-current Stall Prevention during Operation 
 
   
  Default: 
120/120/120/120 
  Settings  230V/460V series 
Light load: 0–130% (100%: drive’s rated current) 
Normal load: 0–160% (100%: drive’s rated current) 
575V/690V series 
Light load: 0–125% (100%: drive’s rated current) 
Normal load: 0–150% (100%: drive’s rated current) 
 
  This parameter only works in VF and SVC control modes. 
  This is a protection for the drive to decrease output frequency automatically when the motor 
over-loads abruptly during constant motor operation. 
  If the output current exceeds the setting value for Pr.06-04 when the drive is operating, the drive 
decreases output frequency (according to Pr.06-05) to prevent the motor from stalling. If the 
output current is lower than the setting value for Pr.06-04, the drive accelerates (according to 
Pr.06-05) again to the setting frequency.

    5: By automatic acceleration / deceleration   
 Sets  the  acceleration  /  deceleration  time  selection  when  stall  prevention  occurs  at  constant 
speed.
