What it means

Communication with the acceleration sensor (or a force sensor sharing the channel) was interrupted mid-operation - the sensor went silent on the main board.

Common causes

Ranked by what technicians most often find, most likely first.

  1. Another alarm in the history is the trigger - including force-sensor alarms if one is fitted.
  2. Sensor/cable fault per the SRVO-098 list.
  3. Main board or CPU card fault.

How to fix it

  1. Clear any accompanying alarms first, including force-sensor alarms.
  2. Work the SRVO-098 connection checks.
  3. Escalation order: image backup, then main board, then CPU card; if it persists, document the sequence of events and contact FANUC.
