SI P1 (CU): Defect in a monitoring channel

Was bedeutet F01611 ?

The drive-integrated "Safety Integrated" function on processor 1 has detected a fault in the crosswise data comparison between its two monitoring channels, initiating a STOP F. This often leads to fault F01600 as a subsequent response. A defect in a safety monitoring channel is a critical safety system failure that must be resolved to ensure the safe operation of the machine and compliance with safety standards.

• Internal hardware fault within the Safety Integrated module, leading to a discrepancy between the two monitoring channels.
• Excessive electromagnetic interference (EMI) affecting the internal communication paths of the safety processor.
• Firmware inconsistency or corruption within the Safety Integrated function, preventing proper cross-channel comparison.
• Failure of an internal test pulse or a sensor feedback path within the dual-channel safety architecture.

1. 1

   Check for strong EMI sources near the drive and its control unit. Relocate signal cables if they are routed too close to power cables.

2. 2

   Perform a power cycle of the drive system (main power off/on) to reset the Safety Integrated module.

3. 3

   Verify the firmware version of the control unit (r0018) against the recommended version for the installed safety option module.

4. 4

   If the fault persists, consider replacing the control unit (CU) as an internal hardware defect is likely.
