oH1
Heatsink Overheat
The ambient temperature is high and the heatsink
temperature of the drive is more than the
oH1
detection level.
•
Measure the ambient temperature.
•
Increase the airflow in the control panel.
•
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.
The load is too heavy.
•
Measure the output current.
•
Decrease the load.
•
Decrease the value set in
C6-02 [Carrier Frequency Selection]
.
Note:
•
The drive detects this fault if the heatsink temperature of the drive is more than the
oH1
detection level.
o2-04 [Drive Model (KVA) Selection]
determines the
oH1
detection level.
•
Do a Fault Reset to clear the fault.
•
L5-08 [Fault Reset Enable Select Grp2]
disables the Auto Restart function.

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
C1-01 to C1-04 [Acceleration/
Deceleration Times]
.
•
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
E1-04 to E1-10 [V/f Pattern Parameters]
. Decrease the
values set in
E1-08 [Mid Point A Voltage]
and
E1-10 [Minimum
Output Voltage]
.
Note:
If the values set in
E1-08
and
E1-10
are too low, the overload
tolerance will decrease at low speeds.
Note:
•
When
H3-02 or H3-10 = E [MFAI Function Selection = Motor Temperature (PTC Input)]
, the drive detects this fault if the motor overheat signal entered to analog input terminals
A1 or A2 is more than the alarm detection level.
•
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
L1-03 [Motor Thermistor oH Alarm Select]
.

Motor Overheat Fault (PTC Input)
The motor has overheated.
•
Check the load level, acceleration/deceleration time, and motor

.
Note:
If
E1-08
and
E1-10
are set too low, the overload tolerance will
decrease at low speeds.
Note:
•
The drive detects this fault if the motor overheat signal that was entered to an analog input terminals A1or A2 is more than the alarm detection level. (If
H3-02 or H3-10= E [MFAI
Function Select = Motor Temperature (PTC Input)]
was set.)
•
Do a Fault Reset to clear the fault.

oL1
Motor Overload
The load is too heavy.
Decrease the load.
Note:
Reset
oL1
when
U4-16 [Motor oL1 Level]
< 100.
The acceleration/deceleration times or cycle times are
too short.
•
Examine the acceleration/deceleration times and the motor start/
stop frequencies (cycle times).
•
Increase the values set in
C1-01 to C1-04 [Acceleration/
Deceleration Times]
