Over-current Stall Prevention during Acceleration
Default: 120 / 180
Settings
Normal duty: 0–150% (100% corresponds to the rated current of the drive)
Heavy duty: 0–200% (100% corresponds to the rated current of the drive)
 If the motor load is too large or the drive’s acceleration time is too short, the output current of the
drive may be too high during acceleration, and it may cause motor damage or trigger protection
functions (OL or OC). Use this parameter to prevent these situations.
 During acceleration, the output current of the drive may increase abruptly and exceed the setting
value of Pr.06-03. In this case, the drive stops accelerating and keeps the output frequency
constant, and then continues to accelerate until the output current decreases.
 Refer to Pr.06-16 for the stall level in flux weakening region. The protection curve:
