官方故障排除步骤
Message value: Drive object: SERVO, VECTOR Reaction: OFF1 (OFF2, OFF3) Acknowledge: IMMEDIATELY Cause: After starting the search for reference, the axis moved through the maximum permissible distance to search for the reference cam without actually finding the reference cam. Remedy: - check the "reference cam" binector input (BI: p2612). - check the maximum permissible distance to the reference cam (p2606). - if axis does not have any reference cam, then set p2607 to 0.
