官方故障排除步驟
Message value: Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: NONE Cause: The configured times for PROFIBUS communication are not permitted and the DP cycle is used as the actual value acquisition cycle for the safe movement monitoring functions: Isochronous PROFIBUS: the total of Ti and To is too high for the set DP cycle. The DP cycle should be at least 1 current controller cycle greater than the sum of Ti and To. Non-isochronous PROFIBUS: the DP cycle must be at least 4 x current controller cycle. Remedy: Configure Ti and To low so that they are suitable for the DP cycle or increase the DP cycle time. Option for enabled drive-based SI monitoring (p9601/p9801 > 0): Use the actual value sampling cycle p9511/p9311 and, t herefore, set it independently of the DP cycle.
