I have a 30ia, 2000iB/210F gripper robot.
Suddenly it is showing DTERR alarm for all 6 axes. & also showing overtravel alarm.
Particular robot doesn't have any overtravel limit switch.
Action taken.
1. Power recycled
2. tried reset pulse coder alarm
3. Replaced RP1 cable
4. Replaced Servo amp
5. Even when removed J1 axis pulsecoder cable , not showing BZAL alarm
but still showing the DTERR alarm *& overtravel alarm
Plz help......
