• Review the possible solutions provided for handling noise interference.
• Review the section on handling noise interference and check the control circuit lines, main circuit lines,
and ground wiring.
• Check if the fault occurs simultaneously with overexcitation function operation.
• Consider motor flux saturation and reduce the value of n3-13 (Overexcitation Deceleration Gain).
• Set b3-01 to 1 to enable Speed Search at Start.
• Program the Speed Search command input through one of the multi-function contact input terminals
(H1-oo = 61 or 62).
Use a larger drive.

Heatsink Overheat
oH
The heatsink temperature exceeded the overheat pre-alarm level set to L8-02. The 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.
