oH
Heatsink Overheat
The ambient temperature is high and the heatsink
temperature of the drive is more than the value set
in
L8-02 [Overheat Alarm 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.
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.
oH3
Motor Overheat (PTC Input)
The thermistor wiring that detects motor
temperature is defective.
Correct wiring errors.
oH4
Motor Overheat Fault (PTC Input)
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
E1-04 to E1-10 [V/f Pattern Parameters]
. For motor 2,
adjust
E3-xx [V/f Pattern for Motor 2]
settings. For motor 3,
adjust
E7-xx [V/f Pattern for Motor 3]
settings. Decrease the
values set in
Ex-08 [Mid Point A Voltage]
and
Ex-10
[Minimum Output Voltage]
.
Note:
If
Ex-08
and
Ex-10
are set too low, the overload tolerance will
decrease at low speeds.
