Fieldbus fault

What does 53 mean?

The data connection between the fieldbus master and the drive's fieldbus option board is defective, leading to a loss of communication. This prevents the drive from being controlled or monitored via the fieldbus network, disrupting integrated system operations. An incorrect installation or a faulty fieldbus master are common causes.
