Description
The robot has moved beyond a hardware limit switch on the axes. It is factory-placed in the overtravel state for packing purposes.
Remedy
1. Select [System OT release] on the overtravel release screen to release each robot axis from the overtravel state. 2. Press the SHIFT key, and press the alarm release button to reset the alarm condition. 3. Continuously press the SHIFT key, and jog the robot to bring all axes into the movable range. 4. Check the FS2 fuse on the servo amplifier.
Field diagnosis
An axis has reached its electrical limit switch. On delivery, robots are deliberately left in the overtravel condition for shipping.
What to check
- On the overtravel release screen, select the system release, then reset while holding SHIFT; still holding SHIFT, jog each axis back within its stroke.
- Jogging is blocked in the overtravel direction while the alarm is active.
- Note: On models without a physical limit switch, this code rather points to an RDI cable or an input at 0 V.

Indicative field information — the robot manufacturer's manual and safety procedures always prevail. Never bypass a safety device; apply lockout/tagout (LOTO) before any physical intervention. How this reference is built →
