10.4 Fieldbus timeout
WARNING
Risk of crushing if the drive keeps running unintentionally after a communication
timeout or fault elimination.
Severe or fatal injuries or damage to property.
• Note that the communication timeout resets automatically as soon as communic-
ation with the lower-level device is reestablished. That is, the drives receive the
current process output data from the PLC straight away after system bus com-
munication restarts.
• Disconnect the drive controller from the power supply before rectifying a fault if
automatic restart of the driven machine after fault elimination is not permitted for
safety reasons.
A fieldbus timeout can occur in device when you switch off the fieldbus master or if
there is a wire break in the fieldbus cabling:
• The "S1" LED indicates that no new user data is being received.
• The process data for all subordinate devices has been set to Value"0". This means
that all drives connected to the device are stopped.
• The digital outputs are set to "0".
