Over-Current Stall Prevention during Acceleration
Default:
Settings 230V / 460V models
Heavy duty: 0–195% (100% corresponds to
the rated current of the drive)
150
Super Heavy duty: 0–210% (100%
corresponds to the rated
current of the drive)
150
575V / 690V models
Light duty: 0–125% (100% corresponds to
the rated current of the drive)
120
Normal duty: 0–150% (100% corresponds to
the rated current of the drive)
120
Heavy duty: 0–180% (100% corresponds to
the rated current of the drive)
150
100% corresponds to the rated current of the drive (Pr.00-01).
This parameter only works in VF, VFPG, and SVC control mode.
The default for Pr.06-03 and Pr.06-04 is 150%, and the maximum value is 200%. If the DC voltage
is higher than the 700 V
DC
(460V models) or 350 V
DC
(230V models), the maximum value for Pr.06-
03 and Pr.06-04 is 180%.
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 the drive’s
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.
