Heatsink Overheat
oH
The temperature of the heatsink exceeded the value set to L8-02. 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).
• After replacing the drive, reset the cooling fan maintenance parameter (o4-03 = "0").
Overheat 1 (Heatsink Overheat)
oH1
The temperature of the heatsink has exceeded 10 °C plus the default value of L8-02.
• 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.
• Lower the carrier frequency (C6-02).
• Reduce the load.
• Check the maintenance time for the cooling fan (U4-04).
• After replacing fan, reset the fan maintenance time (o4-03 = "0").
• Check the current level of the terminal.
• Set the current to the control circuit terminal to be 20 mA or less.
Motor Overheat Alarm (PTC Input)
oH3
• The motor overheat signal to analog input terminal A1 or A2 exceeded the alarm detection level.
• Detection requires multi-function analog input H3-02 or H3-10 be set to "E".
