Abstract
The present invention relates to a method for controlling an inverter to prevent an unnecessary fan trip. The method includes: receiving a fan current; when the fan current is above a high trip level or is below a low trip level, incrementing an error count; when the error count reaches an error count maximum value, incrementing a trip count and initializing the error count; and when the trip count reaches a trip count maximum value, generating a fan trip signal.
