官方故障排除步驟
Message value: Drive object: All objects Reaction: OFF1 Acknowledge: IMMEDIATELY Cause: The global control telegram to sync hronize the clock cycles has failed - in cyclic operation - for several DP clock cycles or has violated t he time grid specified in the param eterizing telegram over several consecutive DP clock cycl es (refer to the bus cycle time, Tdp and Tpllw). Remedy: - check the PROFIBUS cables and connectors. - check whether communication was briefly or permanently interrupted. - check the bus and master for utilization level (e.g. bus cycle time Tdp was set too short).
