Communication Timeout Fault

What does CE mean?

This fault indicates a loss of serial communication (e.g., Modbus) between the drive and its control system for more than 2 seconds, affecting parameters like H5-04 and H5-05. The drive will execute a programmed stopping method, becoming unresponsive to external commands. Prolonged communication loss can lead to process interruption and potential safety hazards if the drive is not properly controlled.
