The gain during overexcitation operation is too
large.
•
Find the time when the fault occurs.
•
If the fault occurs at the same time as an overexcitation
operation, decrease
n3-13 [OverExcBr Gain]
and consider the
motor flux saturation.
The drive received a Run command while the motor
was coasting.
•
Examine the sequence and input the Run command after the
motor fully stops.
•
Set
b3-01 = 1 [SpSrch@Start Selection = Enabled]
or set
H1-
xx = 67, 68 [SpdSrch Fmax, SpdSrch Fref]
to input speed
search commands from the MFDI terminals.
In PM Control Methods, the setting of the motor
code is incorrect.
•
Enter the correct motor code to
E5-01 [PM Mot Code
Selection]
as specified by the PM motor.
•
For specialized motors, refer to the motor test report and set
E5-xx [PM Motor Settings]
correctly.
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-xx [PM Motor Parameters]
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 an ordinary IPM motor.
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.
•
Decrease
C6-02 [Carrier Frequency Selection]
. Or set
C6-02
= B
.
Speed search does not complete at start when you
set
A1-02 = 8 [EZ Vector]
and use an induction
motor.
When
E9-01 = 0 [Motor Type Selection = IM]
, set
b3-24 = 2
[SpSrch Method Selection = Current Det2]
.
An overcurrent occurred during overexcitation
deceleration.
•
Decrease
n3-13 [OverExcBr Gain]
.
•
Decrease
n3-21 [OverExcBr Current Level]
.
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.

Overcurrent2
When
A1-02 = 5, 6, 8 [Control Method = PM
OLVector, PM AOLVector, or EZ Vector]
, the output
current is more than the value set in
L8-27
[OverCurr Det Gain]
.
Correct the value set in
L8-27
.
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.
