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 [CoolingFan OperationTime 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 to H2-05 = 10 [MFDO Function Select = Alarm]
will be ON.
•
Set the stopping method for this error in
L8-03 [Overheat Pre-Alarm Selection]
.

oH2
External Overheat (H1-XX=B)
oH2 [External Overheat (H1-XX=B)]
signal was
input from an external device.
1. Identify the external device that output the overheat alarm
and remove the cause of the problem.
2. Clear the
Overheat Alarm (oH2) [H1-xx = B]
that was set to
MFDI terminals S1 to S10.
Note:
If the drive detects this error, the terminal assigned to
H2-01 to H2-05 = 10 [MFDO Function Select = 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.
•
Examine the load level, acceleration/deceleration times, and
motor start/stop frequency (cycle time).
•
Decrease the load.
•
Increase the values set in
C1-01 to C1-08 [Acceleration/
Deceleration Time]
.
•
Set
E2-01 [Motor 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
E1-xx [V/f Pattern Parameters]
settings. Decrease the
values set in
E1-08 [Mid Point A Voltage]
and
E1-10
[Minimum Output Voltage]
. For motor 2, adjust
E3-xx [V/f
Pattern for Motor 2]
settings. Decrease the values set in
E3-08
[Motor 2 Mid Point A Voltage]
and
E3-10 [Motor 2 Minimum
Output Voltage]
. For motor 3, adjust
E7-xx [V/f Pattern for
Motor 3]
settings. Decrease the values set in
E7-08 [Motor 3
Mid Point A Voltage]
and
E7-10 [Motor 3 Minimum Output
Voltage]
.
Note:
If
Ex-08
and
Ex-10
are set too low, the overload tolerance will
decrease at low speeds.
Note:
•
The drive detects this error if the motor overheat signal that was entered to an analog input terminals A1, A2, or A3 is more than the alarm detection level. (If
H3-02, H3-10,
or H3-06 = E [MFAI Function Select = Motor Temperature (PTC input)]
was set.)
•
If the drive detects this error, the terminal assigned to
H2-01 to H2-05 = 10 [MFDO Function Select = 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 Thermistor oH Alarm 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 the overtorque detection parameters.
Note:
•
The drive detects this error if the motor current and torque are more than the value set in
S6-02
for longer than
S6-03
.
•
If the drive detects this error, the terminal assigned to
H2-01 to H2-05 = 10 [MFDO Function Select = Alarm]
will be ON.
•
Set the conditions that trigger the minor fault using
S6-01 [OverT Detect Operation Select 1]
.

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 the overtorque detection parameters.
Note:
•
The drive detects this error if the motor current and torque are more than the value set in
S6-05 [Overtorque Detection Level 2]
for longer than
S6-06 [Overtorque Detection
Time 2]
.
•
If the drive detects this error, the terminal assigned to
H2-01 to H2-05 = 10 [MFDO Function Select = Alarm]
will be ON.
•
Set the conditions that trigger the minor fault using
S6-04 [OverT Detect Operation Select 2]
.
