问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Drive, encoder: Positi on tracking, incremental encoder not possible 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: Fault cause: %1, component number: %2, encoder data set: %3 Drive object: SERVO, VECTOR Reaction: OFF2 (IASC/DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2) Acknowledge: IMMEDIATELY (POWER ON) Cause: The requested position tracking for incremental encoders is not supported. Fault value (r0949, interpret hexadecimal): ccccbbaa hex aa = encoder Data Set number bb = component number cccc = fault cause cccc = 00 hex = 0 dec The encoder type does not support the "Pos ition tracking incremental encoder" function. cccc = 01 hex = 1 dec Position tracking cannot be activated because the me mory of the internal NVRAM is not sufficient or a Control Unit does not have an NVRAM. cccc = 04 hex = 4 dec A linear encoder is used that does not support the position tracking function. See also: p0404 (Encoder configuration effect ive), p0411 (Measuring gear, configuration), r0456 (Encoder configuration supported) Remedy: - check the encoder parameterization (p0400, p0404). - use a Control Unit with sufficient NVRAM. - if required, deselect position tracking for the incremental encoder (p0411.3 = 0).
