• 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.
Overexcitation gain is set too high
• Check if the fault occurs simultaneously with overexcitation function operation.
• Consider motor flux saturation and reduce the value of n3-13 (Overexcitation Deceleration Gain).
