Cause : Current limit - A "current limit" feature in a Variable Frequency Drive (VFD) is designed to protect the motor and the VFD itself from excessive current draw. This feature prevents the motor from drawing more current than it should under normal operating conditions, which can occur due to various reasons such as mechanical overload, voltage fluctuations, or improper settings.

  • The motor current has exceeded the value in parameter 209 for longer than permitted in parameter 310.
