changed during operation.
The same option cards or the same type of option
cards are connected to connectors CN5-A and B.
A fault occurred in the option card.
A fault occurred in the option card.
The ambient temperature is high and the heatsink
temperature of the drive is more than the value set in
L8-02 [Overheat Alarm Level].
The ambient temperature is high and the heatsink
temperature of the drive is more than the oH1
detection level.
The thermistor wiring that detects motor temperature
is defective.
The motor has overheated.
The load is too heavy.

• 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.
• 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.
Correct wiring errors.
• 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.
Decrease the load.
Note:
Reset oL1 when U4-16 [Motor oL1 Level] < 100.
