SRVO-069: CRCERR alarm (pulse coder data corrupt)
Encoder serial data arrived corrupted mid-transmission - same communication pathway problem as DTERR, caught by the data check instead of a timeout.
What it means
Encoder serial data arrived corrupted mid-transmission - same communication pathway problem as DTERR, caught by the data check instead of a timeout.
Common causes
Ranked by what technicians most often find, most likely first.
- Same suspect list as SRVO-068: connectors, shield grounding, cabling, encoder, amplifier.
How to fix it
- Work the SRVO-068 remedy sequence - connectors, shielding, cable test, then hardware in order of cost. Power-cycle to clear.
