Causes
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.
The current flowing in the motor is more than the
value set in L8-27 [OverCurr Det Gain] for PM
Control.
The control method is set incorrectly for the motor.
The motor main circuit cable is too long.
Speed search does not complete at start when you
use an induction motor in EZOLV control.
Causes
The option card connected to connector CN5-A is
not compatible.

Possible Solutions
• 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.
Correct the value set in L8-27.
Set A1-02 [Control Method] correctly.
Replace the drive with a larger capacity model.
When E9-01 = 0 [Motor Type Selection = IM], set b3-24 = 2
[SpSrch Method Selection = Current Det2].
Possible Solutions
Connect the option card to the correct connector.
