If the drive detects the fault at start
or in the low speed range (10% or
less) and
n8-57 = 1 [HFI Overlap
Selection = 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 P
Gain]
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 Selection]
correctly.
The motor main circuit cable is too
long.
•
Replace the drive with a larger capacity

•
Decrease
C6-02 [Carrier Frequency]
. Or
set
C6-02 = B
.
Speed search does not complete at
start when you set
A1-02 = 8 [EZ
Vector Control]
and use an
induction motor.
When
E9-01 = 0 [Motor Type Selection =
Induction (IM)]
, set
b3-24 = 2 [Speed
Search Method Selection = Current
Detection Speed Search]
.
An overcurrent occurred during
overexcitation deceleration.
•
Decrease
n3-13 [OverexcitationBraking
(OEB) Gain]
.
•
Decrease
n3-21 [HSB Current
Suppression Level]
.
oC2
Overcurrent2
When
A1-02 = 5, 6, 8 [Control
Method Selection = OLV/PM,
AOLV/PM, or EZOLV]
, the output
current is more than the value set
in
L8-27 [Overcurrent Detection
Gain]
.
Correct the value set in
L8-27
.
