Code Name Causes Possible Solutions
If the drive detects the fault at start or in the low
speed range (10% or less) and n8-57 = 1 [High-
Freq Injection = Enabled] for PM Control methods,
the high frequency injection gain is too high.
• Set E5: PM MOTOR SETTINGS correctly or do Rotational
Auto-Tuning.
• Decrease the value of n8-41 [HFI PoleDet Pgain] in 0.5 unit
increments.
Note:
Set n8-41 > 0.0 for IPM motors.
The current flowing in the motor is more than the
value set in L8-27 [OverCurr Det Gain] for PM
Control.
Correct the value set in L8-27.
The control method is set incorrectly for the motor. Set A1-02 [Control Method] correctly.
The motor main circuit cable is too long. Replace the drive with a larger capacity model.
Speed search does not complete at start when you
use an induction motor in EZOLV control.
When E9-01 = 0 [Motor Type Selection = IM], set b3-24 = 2
[SpSrch Method Selection = Current Det2].
Note:
• This fault occurs if the drive sensors detect a drive output current more than the specified overcurrent detection level.
• Do a Fault Reset to clear the fault.
