问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Drive encoder: Configuration position tracking 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: Component number: %1, encoder data set: %2, drive data set: %3, fault cause: %4 Drive object: SERVO, VECTOR Reaction: OFF2 (IASC/DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2) Acknowledge: IMMEDIATELY (POWER ON) Cause: The configuration of the posi tion tracking is not supported. Position tracking can only be ac tivated for absolute encoders. For linear axes, it is not possible to simultaneous ly activate the position tracking for load- and measuring gear. Fault value (r0949, interpret hexadecimal): ddccbbaa hex aa = encoder data set bb = component number cc = drive data set dd = fault cause dd = 00 hex = 0 dez An absolute encoder is not being used. dd = 01 hex = 1 dez 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. dd = 02 hex = 2 dez For a linear axis, the position tracking was activated for the load and measuring gear. dd = 03 hex = 3 dez Position tracking cannot be activated because position tracking with anot her gear ratio, axis type or tolerance window has already been detected for this encoder data set. dd = 04 hex = 4 dez A linear encoder is being used. See also: p0404 (Encoder configuration effective), p0411 (Measuring gear, configuration) Remedy: - use an absolute encoder. - if necessary, de-select the position tracking ( p0411 for the measuring gear, p2720 for the load gear). - use a Control Unit with sufficient NVRAM. - Only activate position tracking of the load gear in the same encoder data set if the gear ratio (p2504, p2505), axis type (p2720.1) and tolerance window (p2722) are also the same.
