Selection for Over-voltage Stall Prevention
Factory Setting: 0
Settings 0: Traditional over-voltage stall prevention
1: Smart over-voltage prevention
When Pr.06-02 is set to 1, the drive will maintain DCbus voltage when decelerating and prevent
OV.

Over-current Stall Prevention during Acceleration
Settings Normal duty: 0~160% (100%: drive’s rated current)
Factory Setting: 120
Heavy duty: 0~180% (100%: drive’s rated current)
Factory Setting: 150
If the motor load is too large or drive acceleration time is too short, the AC drive output current may
increase abruptly during acceleration and it may cause motor damage or trigger protection
functions (OL or OC). This parameter is used to prevent this situation.
