• Check which motor control method the drive is set to (A1-02).
• For IM motors, set A1-02 = "0" or "2".
• For PM motors, set A1-02 = "5".
Use a larger inverter.

Heatsink Overheat
oH
The temperature of the heatsink exceeded the value set to L8-02 (90-100°C).
Default value for L8-02 is determined by drive capacity (o2-04).
• Check the temperature surrounding the drive. Verify temperature is within
drive specifications.
• Improve the air circulation within the enclosure panel.
• Install a fan or air conditioner to cool the surrounding area.
• Remove anything near the drive that might be producing excessive heat.
• Measure the output current.
• Decrease the load.
• Lower the carrier frequency (C6-02).
• Replace the cooling fan.
• After replacing the drive, reset the cooling fan maintenance parameter
(o4-03 = "0").
Overheat 1 (Heatsink Overheat)
The temperature of the heatsink has exceeded the value set to L8-02
(100-110°C). Default value for L8-02 is determined by drive capacity (o2-04).
• Check the temperature surrounding the drive.
• Improve the air circulation within the enclosure panel.
• Install a fan or air conditioner to cool the surrounding area.
• Remove anything near the drive that might be producing excessive heat.
• Measure the output current.
• Reduce the load.
• Lower the carrier frequency (C6-02).
