Heatsink Overheat
The ambient temperature is high and the heatsink
temperature is more than the
L8-02 [Overheat Alm
Level]
.
•
Measure the ambient temperature.
•
Increase the airflow around the drive.
•
Install a cooling device (cooling fan or air conditioner) to
lower the ambient temperature.
•
Remove objects near the drive that are producing too much
heat.
There is not sufficient airflow around the drive.
•
Give the drive the correct installation space as shown in the
manual.
•
Make sure that there is sufficient circulation around the control
panel.
•
Examine the drive for dust or other unwanted materials that
could clog the cooling fan.
•
Remove unwanted materials that prevent air circulation.
The internal cooling fan or fans have stopped.
1.
Use the procedures in this manual to replace the cooling fan.
2.
Set
o4-03 = 0 [Fan.Oper Setting = 0 h]
to reset the cooling
fan operation time.
Note:
•
The drive detects this error if the heatsink temperature of the drive is more than
L8-02
.
•
If the drive detects this error, the terminal assigned to
H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm]
will be ON.
•
Set the stopping method for this fault in
L8-03 [Overheat Pre-Alarm Selection]
.

oH2
External Overheat (H1-XX=7D)
An external device sent an
oH2
.
1.
Find the external device that output the overheat alarm.
2.
Remove the cause of the problem.
3.
Clear the
Overheat Alarm (oH2) [H1-xx = 7D]
that was set to
MFDI terminals DI1 to DI8.
Note:
If the drive detects this error, the terminal assigned to
H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm]
will be ON.

oH3
Motor Overheat (PTC Input)
The thermistor wiring that detects motor
temperature is defective.
Correct wiring errors.
A fault occurred on the machine.
Example: The machine is locked.
Examine the machine and remove the cause of the fault
The motor has overheated.
•
Check the load level, acceleration/deceleration time, and motor
start/stop frequency (cycle time).
•
Decrease the load.
•
Increase the values set in Acceleration/Deceleration Times
C1-
01 to C1-08
.
•
Set
E2-01 [Mot Rated Current (FLA)]
correctly to the value
specified by the motor nameplate.
•
Make sure that the motor cooling system is operating correctly,
and repair or replace it if it is damaged.
•
Adjust V/f Pattern Parameters
E1-04 to E1-10
. For motor 2,
adjust
E3-04 to E3-10
. Decrease the values set in
E1-08 [Mid
A Voltage]
and
E1-10 [Min Output Voltage]
.
Note:
If the values set in
E1-08
and
E1-10
are too low, the load
tolerance will decrease when operating the drive in the low
speed range.
Note:
•
The drive detects this fault if the motor overheat signal that was entered to an analog input terminal A3 is more than the alarm detection level when
H3-06 = 16 [AI3
Function Selection = Motor Temperature (PTC Input)]
.
•
If the drive detects this error, the terminal assigned to
H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm]
will be ON.
•
If the drive detects this error, it will operate the motor as specified by the stopping method set in
L1-03 [Motor oH AL Reaction Select]
.

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 [Trq Det1 Level]
and
L6-03 [Trq Det1 Time]
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 assigned to
H2-01, H2-02, and H2-03 = 4 [Multi-Function Digital Output 1, Multi-Function Digital Output 2, and Multi-Function
Digital Output 3 = Alarm]
will be ON.
•
Set the conditions that trigger the minor fault using
L6-01 [Trq Det1 Select]
.
