Safety fence open. (for E0x series controllers)

Error handling: Motor power OFF.
Error reset: Possible.

Content: The safety fence open signal has been input externally. If system switch SF_OPEN_ERROR is OFF, this is not an error state and a message is displayed in the teach pendant message area. If SF_OPEN_ERROR is ON, or the software version does not support the SF_OPEN_ERROR switch, this is an error state.

Main causes:

1. The external contacts at connector X8 (pins 1-2, pins 3-4) on the power sequence board are open.

2. A problem with the power sequence board.

Countermeasures:

1. Check whether an external safety fence open signal is input.

2. If no signal is input, replace the power sequence board.

Reference: On the teach pendant screen, select <Display 1> → → <Safety Circuit Monitor 2> to check the safety circuit status. For details of the safety circuit monitor, refer to the Operation Manual.
