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.
•
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]
. For motor 2,
adjust
E3-04 to E3-10
. Decrease the values set in
E1-08 [Mid
Point A Voltage]
and
E1-10 [Minimum Output Voltage]
.
Note:
If
E1-08
and
E1-10
are set too low, the overload tolerance will
decrease at low speeds.
oL1
Motor Overload
The load is too heavy.
Decrease the load.
Note:
Reset
oL1
when
U4-16 [Motor oL1 Level]
< 100.
