代码 233429: <location>Encoder 3: Position diff erence, hall sensor/track C/D and A/B too large

问题描述与安全警告

Siemens SINUMERIK 840D CNC 触发了严重的 <location>Encoder 3: Position diff erence, hall sensor/track C/D and A/B too large 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: %1 Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: The error for track C/D is greater than +/-15 ° mechanica l or +/-60 ° electrical or the error for the Hall signals is greater than +/-60 ° electrical. One period of track C/D corresponds to 360 ° mechanical. One period of the Hall signal co rresponds to 360 ° electrical. The monitoring responds if, for exam ple, Hall sensors are connected as equivalent for the C/D tracks with the incorrect rotational sense or supply values that are not accurate enough. Alarm value (r2124, interpret decimal): For track C/D, the following applies: Measured deviation as mechanica l angle (16 bits with sign, 182 dec corresponds to 1 °). For Hall signals, the following applies: Measured deviation as el ectrical angle (16 bits with si gn, 182 dec corresponds to 1 °). Remedy: - track C or D not connected. - correct the direction of rotation of the Hall s ensor possibly connected as equivalent for track C/D. - check that the encoder cables are routed in compliance with EMC. - check the adjustment of the Hall sensor.
