FANUC Alarm SRVO-004 — SERVO Fence open

Description

On the terminal block TBOP4 of the panel board, no connection is made between 5 (EAS1) and 6 (EAS11) or between 7 (EAS2) and 8 (EAS21). If a safety fence is connected between 5 (EAS1) and 6 (EAS11) or between 7 (EAS2) and 8 (EAS21), the door of the safety fence is open.

Remedy · Remède

1. If a safety fence is connected, close the door. 2. Check the switch and cable connected to 5 (EAS1) and 6 (EAS11) or 7 (EAS2) and 8 (EAS21). 3. When this signal is not used, make a connection between 5 (EAS1) and 6 (EAS11) or between 7 (EAS2) and 8 (EAS21). 4. If SRVO-004 (Fence open), SRVO-007 (External emergency stops), SRVO-213 (Fuse Blown (Panel PCB)), and SRVO-280 (SVOFF input) occur simultaneously, it is likely that FUSE1 on the panel board has blown. Check the fuse. If it has blown, remove the cause, then replace the fuse. Else, check the external voltage on EXT24V and EXT0V (TBOP6). If external 24V and 0V is not used check the jumper pins between EXT24V and INT24V, EXT0V and INT 0V (TBOP6). 5. If the problem still exists, replace the panel board.
