Hello ,

There is a safety switch on each axis for over travel movement. I think the limit switch or proximity switch is touched or it is shot-circuit. So hold the shift key and jog the robot in working range. And RESET the alarm. 

Dear Chadwick,

SRVO-005 SERVO Robot overtravel alarm is explained in detail below:

Cause: A Robot overtravel limit switch, is pressed.

Remedy: To determine which axis is overtraveled:

1. Press MENU

2. Select MANUAL FCTNS

3. Press F1, [TYPE]

4. Select OT_RELEASE Menu. The axis that is overtraveled will display TRUE in either OT_MINUS or OT_PLUS

5. Move the cursor to the OT PLUS or OT MINUS value of the axis in overtravel

6. Press F2, RELEASE. The value of the overtraveled axis should change back to FALSE

7. Press and hold down the SHIFT key until you have completed steps a through d.

a. Press RESET and wait for servo power.

b. Press COORD until you select the JOINT coordinate system.

c. Continuously press and hold the DEADMAN switch and turn the teach pendant ON/OFF switch to ON.

d. Jog the overtraveled axis off the overtravel switch. When you have finished jogging, you can release the SHIFT key.

8. Turn the teach pendant ON/OFF switch to OFF and release the DEADMANswitch

9. Check CRM1 connection on axis control PCB if the robot is not in an actual overtravel condition. NOTE: If you accidently release the SHIFT key during this procedure, you will need to repeat Step 7

Dear all,
We have fanuc robot system R-J3iB model.

We are facing same problem servo-005 alarm.

We attempted to follow your instructions but the issue persists. We have identified that the servo-005 alarm is being reset when the shift + reset button is pressed while in manual mode. However, when we release the shift button, the alarm returns.

Kindly provide suggestion.

Hi Baddam,

Can you press POSN and put the robot in Joint coordinate so we can see the values of each axis? 

Hi, Baddam, finally were you able to solve this problem?. I have a Fanuc s420-f robot and i am having the same problem. The error is "4005 robot overtravel". I checked that an axis had a overtravel condition but it was solved.
