代码 231-C670: Motor encoder: EnDat 2.2 not possible %1
问题描述与安全警告
Heidenhain TNC Series CNC 触发了严重的 Motor encoder: EnDat 2.2 not possible %1 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
[Cause of error] - EnDat communication is defective - An encoder with EnDat 2.2 interface is selected in the motor table, although no EnDat 2.2 encoder is connected - The EnDat 2.2 protocol cannot be read - The EnDat measuring system has too low an interpolation rate in EnDat2.2 mode (less than 1024, e.g. EQN 1325). Operation possible only in EnDat2.1 mode [Error correction] - Check whether the encoder supports EnDat 2.2 - Check the motor table (SYS column) - Check the configuration datum motEncType - Check the cable ground and shield - Check the cable (compare the cable ID number with the documentation) - Check the speed encoder cable (defective or too long) - Check the speed encoder - Change EnDat mode (motEncType) - Exchange the motor control board - Inform your service agency
