The torque compensation gain is too large.
Decrease the value set in
C4-01 [Torque Compensation Gain]
to
make sure that the motor does not stall.
Electrical interference caused a problem.
Examine the control circuit lines, main circuit lines, and ground
wiring, and decrease the effects of electrical interference.
The gain during overexcitation operation is too large.
•
Find the time when the fault occurs.
•
If the fault occurs at the same time as overexcitation operation,
decrease the value set in
n3-13 [OverexcitationBraking (OEB)
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 [Speed Search at Start Selection = Enabled]
or set
H1-xx = 61, 62 [Speed Search from Fmax or 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 Motor 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 [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]
.
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.

Duplicate Options
The same option cards or the same type of option
cards are connected to connectors CN5-A, B, and C.
Connect the option card to the correct connector.
Note:
Use connectors CN5-C and CN5-B to connect two encoder
option cards.
Note:
Do a Fault Reset to clear the fault.

Option Card Error Occurred at
Option Port CN5-A
A fault occurred in the option card.
1.
De-energize the drive.
2.
Make sure that the option card is correctly connected to the
connector.
3.
If the problem continues, replace the option card.
Note:
Do a Fault Reset to clear the fault.
