Sign-of-life failure for master control
Siemens · DCM
¿Qué significa F01030 ?
The drive has lost its "sign-of-life" signal from an active PC master control within the configured monitoring time, indicating a communication interruption. Consequently, master control has reverted to the BICO interconnection. This fault stops PC-based control, potentially leading to an uncontrolled state or production halt.
Causas comunes
- Communication cable disconnection or damage between the master controller (e.g., PLC, PC) and the drive interface (e.g., Profibus, Profinet).
- Master controller software application has stopped sending cyclic data (e.g., control word, setpoints) or sign-of-life bits.
- Communication interface module on the drive (e.g., CBE20, Profibus CBP) is defective or has incorrect settings (e.g., P918, P922).
- Excessive communication network load or latency causing timeouts (e.g., higher than P2040 monitoring time).
- Incorrectly configured monitoring time parameter (e.g., P2040) in the drive, too short for the network conditions.
Pasos de reparación & Lista de verificación
Haga clic en los pasos para seguir su progreso.
- 1
Verify the physical communication cable integrity (e.g., Profinet RJ45, Profibus DB9 connector) between the master control and the drive.
- 2
Check the master controller program logic to ensure the cyclic telegram (e.g., PZD, control word) is actively sending data to the drive.
- 3
Increase the monitoring time parameter (e.g., P2040) in the drive configuration in increments (e.g., 100ms, 200ms) to accommodate network latency.
- 4
Diagnose the communication interface module status LEDs (e.g., Link/Act, SF on CBE20) for any error indications.
- 5
Ping the drive's IP address (for Profinet) or check network status (for Profibus) from the master controller to verify basic network connectivity.
- 6
Verify the communication telegram configuration (e.g., P918 for send PZD, P922 for receive PZD) matches both master and drive.
