Cause : Fieldbus interface setpoint timeout comes when the reception of setpoints from the fieldbus interface has been interrupted.

sinamics f01910 indicates a "Fieldbus interface setpoint timeout". This means that the communication between the drive and the master controller (typically a PLC) via the fieldbus (like PROFIBUS DP, PROFINET, etc.) has been interrupted or has timed out because the drive hasn't received a new setpoint within the expected timeframe.

Troubleshooting Steps:

Follow these steps to correct sinamics f01910:

• Check Fieldbus Cables and Connections: Carefully inspect all cables and connectors for damage and secure connections at both ends.
• Verify Master Controller Status: Ensure the PLC or master controller is running correctly and actively sending setpoints to the drive.
• Check Drive Parameters: Using the drive's keypad or a commissioning tool, verify the fieldbus configuration parameters (address, baud rate, telegram, setpoint source) match the master controller's settings.
• Monitor Communication Signals: If possible, use diagnostic tools to monitor the fieldbus communication signals to identify any interruptions or errors.

How to Reset the F01910 Fault:

Once the underlying communication issue is resolved, you can typically reset the F01910 fault by:

• Pressing the RESET button on the drive keypad.
• Cycling the power to the drive.
• Sending a reset command from the master controller (if configured).
