Hva betyr E5 ?

The drive detected a communication watchdog error on the MECHATROLINK network, indicating a problem with data reception from the controller. This can lead to loss of control, unexpected motor stops, and disrupted automation sequences.

• Break in the MECHATROLINK communication cable (e.g., damaged copper, loose connector).
• MECHATROLINK master controller not sending communication frames within the expected watchdog interval.
• Incorrect MECHATROLINK station address (e.g., S3-01) configured on the drive or master controller.
• Excessive electrical noise on the MECHATROLINK bus causing data corruption or missed frames.
• MECHATROLINK master controller fault or unexpected shutdown preventing frame transmission.
