代码 201691: <location>SI Motion: Ti and To unsuitable for DP cycle
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>SI Motion: Ti and To unsuitable for DP cycle 警报。需要由合格的操作员或维修技师立即处理，以防止在制造周期中对设备造成二次损坏或导致零件报废。在接触电气控制箱之前，请务必确保遵循标准安全和停机挂牌 (LOTO) 程序。
官方故障排除步骤
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.
