今天遇到了x轴26020报警，光栅尺的报警。
不知有没有人遇到过这个报警，能不能指点一下。
另外还有一个问题不明白，为什么报警code是00101000H,而在报警帮助文件中有16位？这个code怎么看呢？

Bit nos. and their significance:
Bit 0: Lighting failed
Bit 1: Signal amplitude too small
Bit 2: Position value incorrect
Bit 3: Overvoltage
Bit 4: Undervoltage
Bit 5: Overcurrent
Bit 6: Battery change necessary
Bit 7: Control check error, Note: SW 4.2 and higher, synchronous linear motor
Bit 8: EnDat encoder, incorrect overlapping, Note: SW 4.2 and higher, synchronous linear motor
Bit 9: C/D track error on encoder ERN1387 or EQN encoder connected or incorrectly configured (not
on EQN, MD 1011)
Bit 10: Log cannot be aborted or old hardware
Bit 11: SSI level detected on data line or no encoder connected or incorrect encoder cable (ERN
instead of EQN)
Bit 12: Timeout while reading measuring value
Bit 13: CRC error
Bit 14: Wrong IPU submodule for direct measuring signal, Note: Only with 611D expansion
Bit 15: Encoder faulty
