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.
The speed search-related parameters are set
incorrectly.
•
Examine the settings for all speed search-related parameters.
•
Adjust
b3-03 [Speed Search Deceleration Time]
.
•
Set
b3-24 = 1 [Speed Search Method Selection = Speed
Estimation]
after Auto-Tuning.
Phase loss in the input power supply is causing the
output current to change.
•
Correct errors with the wiring for main circuit drive input power.
•
Make sure that there is no phase loss, and repair problems.
Overload 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:
•
The drive detects this fault if the electronic thermal protector of the drive started the drive overload protection.
•
Do a Fault Reset to clear the fault.
•
L5-07 [Fault Reset Enable Select Grp1]
disables the Auto Restart function.

Overtorque Detection 1
A fault occurred on the machine.
Example: The machine is locked.
Examine the machine and remove the cause of the fault.
The parameters are incorrect for the load.
Adjust
L6-02 [Torque Detection Level 1]
and
L6-03 [Torque
Detection Time 1]
settings.
Note:
•
The drive detects this fault if the drive output current is more than the level set in
L6-02
for longer than
L6-03
.
•
Do a Fault Reset to clear the fault.
•
If the drive detects this fault, it will operate the motor as specified by the Stopping Method set in
L6-01 [Torque Detection Selection 1]
.
•
L5-07 [Fault Reset Enable Select Grp1]
disables the Auto Restart function.

Overtorque Detection 2
A fault occurred on the machine.
Example: The machine is locked.
Examine the machine and remove the cause of the fault.
The parameters are incorrect for the load.
Adjust
L6-05 [Torque Detection Level 2]
and
L6-06 [Torque
Detection Time 2]
settings.
Note:
•
The drive detects this fault if the drive output current is more than the level set in
L6-05
for longer than
L6-06
.
•
Do a Fault Reset to clear the fault.
•
If the drive detects this fault, it will operate the motor as specified by the Stopping Method set in
L6-04 [Torque Detection Selection 2]
.
•
L5-07 [Fault Reset Enable Select Grp1]
disables the Auto Restart function.

Mechanical Weakening Detection 1
The drive detected overtorque as specified by the
conditions for mechanical weakening detection set in
L6-08 [Mechanical Fatigue Detect Select]
.
Do a deterioration diagnostic test on the machine side.
Note:
•
Do a Fault Reset to clear the fault.
•
If the drive detects this fault, it will operate the motor as specified by the Stopping Method set in
L6-08
.

High Slip Braking Overload
The load inertia is too large.
An external force on the load side rotated the motor.
Something is preventing deceleration on the load
side.
•
Decrease deceleration times in
C1-02, C1-04, C1-06, and C1-08
[Deceleration Times]
for applications that do not use High Slip
Braking.
•
Use a braking resistor to decrease the deceleration time.
The value set in
n3-04 [HSB Overload Time]
is too
small.
•
Increase the value set in
n3-04
.
•
Connect a thermal overload relay to the motor, and set
n3-04 =
1200 s (maximum value)
.
Note:
•
The drive detects this fault if the output frequency is constant for longer than
n3-04
.
•
Do a Fault Reset to clear the fault.
