Possible Solutions
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 model.
•
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
.
