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 current flowing in the motor is more than the
value set in
L8-27 [Overcurrent Detection Gain]
for
PM Control Methods.
Correct the value set in
L8-27
.
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.
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 the value set in
n3-13 [OverexcitationBraking (OEB)
Gain]
.
•
Decrease the value set in
n3-21 [HSB Current Suppression
Level]
.
