oL3
Overtorque 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
.
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm]
will activate.
•
Use
L6-01 [Torque Detection Selection 1]
to set the conditions that trigger the minor fault.

Overtorque 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 error if the drive output current is more than the level set in
L6-05
for longer than
L6-06
.
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm]
will activate.
•
Use
L6-04 [Torque Detection Selection 2]
to set the conditions that trigger the minor fault.

DC Bus Overvoltage
The drive output cable or motor is shorted to ground
(the current short to ground is charging the main
circuit capacitor of the drive through the power
supply).
1.
Examine the motor main circuit cable, terminals, and motor
terminal box, and then remove ground faults.
2.
Re-energize the drive.
The power supply voltage is too high.
Decrease the power supply voltage to align with the drive rated
voltage.
Electrical interference caused a drive malfunction.
•
Examine the control circuit lines, main circuit lines, and ground
wiring, and minimize the effects of noise.
•
Find the source of the noise. If a magnetic contactor is the
source, use Surge Protective Device if necessary.
•
Set
L5-01 ≠ 0 [Number of Auto-Restart Attempts ≠ 0 times]
.
Note:
•
The drive detects this error if the DC bus voltage is more than the
ov
detection level when the Run command has not been input (while the drive is stopped).
•
The
ov
detection level is approximately 410 V for 208/240 V bypasses. The detection level is approximately 820 V for 480 V bypasses.
•
If the drive detects this error, the terminal set to
H2-01 to H2-03 = 10 [MFDO Function Selection = Alarm]
will activate.

Too Many Parameters Changed
You tried to change more than 150 parameters.
Make sure that parameters that do not have an effect on drive
operation are at their default settings.
Note:
•
You can change 150 parameters maximum.
•
If you change parameters that have dependencies, the drive
can detect
ovEr
when the number of changed parameters is
fewer than 150.

Over Pressure Detected
The bypass detected an Over Pressure condition.
•
Check the digital input programmed for Over Pressure Switch
(Z2-0x = 41).
•
Check the connected device for continuity.
•
Check Bypass Digital Input Invert Settings in Z2-09 to Z2-16.

Input Phase Loss
There is a phase loss in the drive input power.
Correct errors with the wiring for main circuit drive input power.
Loose wiring in the input power terminals.
Tighten the terminal screws to the correct tightening torque.
The drive input power voltage is changing too much.
•
Examine the input power for problems.
•
Make the drive input power stable.
Unsatisfactory balance between voltage phases.
•
Examine the input power for problems.
•
Make the drive input power stable.
•
If the input power supply is good, examine the magnetic
contactor on the main circuit side for problems.
