Heatsink Overheat
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).
Cause Possible Solution
Surrounding temperature is too high.
• 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.
Load is too heavy.
• Measure the output current.
• Decrease the load.
• Lower the carrier frequency (C6-02).
Internal cooling fan is stopped.
• Replace the cooling fan. Refer to Cooling Fan Replacement on page 278.
• After replacing the drive, reset the cooling fan maintenance parameter
(o4-03 = “0”).
The cooling fan is clogged.
• Provide the proper installation space around the drive as indicated in the
manual. Refer to Correct Installation Spacing on page 40.
• Allow for the specified space and ensure there is sufficient circulation around
the control panel.
• Check for dust or foreign materials that may have clogged the cooling fan.
• Clear out anything caught in the fan that inhibits air circulation.
