MANUAL OT RELEASE SCREEN


MANUAL OT RELEASE SCREEN

An overtravel error occurs when one or more of the robot axes moves beyond the software motion limits. When this happens one of the overtravel limit switches is tripped and the system does the following:

  • Shuts off drive power to the servo system and applies robot brakes

  • Displays an overtravel alarm error message

  • Lights the operator panel FAULT light

  • Turns on the teach pendant FAULT status indicator

  • Limits motion for the axes involved in the overtravel

If you are jogging in JOINT, the axis number indicating the axis (or axes) in an overtravel will be displayed in the error log. You can manually release overtravel on your system from the MANUAL OT Release screen. The axis that is in overtravel will display TRUE in either OT_MINUS or OT_PLUS.

Refer to Table 1, " MANUAL OT Release Items " for information on the MANUAL OT Release items.
