代码 207447: <location>Load gear: Position trac king, maximum actual value exceeded
问题描述与安全警告
Siemens SINUMERIK 840D CNC 触发了严重的 <location>Load gear: Position trac king, maximum actual value exceeded 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 Drive object: SERVO, VECTOR Reaction: NONE Acknowledge: IMMEDIATELY Cause: When the position tracking of the load gear is confi gured, the drive/encoder (motor encoder) identifies a maximum possible absolute positi on actual value (r2723) that can no longer be represented within 32 bits. Maximum value: p0408 * p2721 * 2^p0419 Fault value (r0949, interpret hexadecimal): ccbbaa hex aa = encoder data set bb = component number cc = drive data set See also: p0408, p0419, p2721 Remedy: - reduce the fine resolution (p0419). - reduce the multiturn resolution (p2721). See also: p0419 (Fine resolution absolute value Gx_X IST2 (in bits)), p2721 (Load gear, rotary absolute gearbox, revolutions, virtual)
