Selectionfor Over-voltage Stall Prevention

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

Over-current Stall Prevention during Acceleration

Settings Normal duty: 0~160% (100%: drive's rated current)
Heavy duty: 0~180% (100%: drive's rated current)
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.
