代碼 231905: <location>Encoder 1: Parameterization error
問題描述與安全警告
Siemens SINUMERIK 840D CNC 觸發了嚴重的 <location>Encoder 1: Parameterization error 警報。需要由合格的操作員或維修技師立即處理,以防止在製造週期中對設備造成二次損壞或導致零件報廢。在接觸電氣控制箱之前,請務必確保遵循標準安全和停機掛牌 (LOTO) 程序。
官方故障排除步驟
Message value: Parameter: %1, supplementary information: %2 Drive object: All objects Reaction: A_INFEED: OFF2 (NONE, OFF1) SERVO: ENCODER (IASC/DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2) VECTOR: ENCODER (IASC/DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2) Acknowledge: IMMEDIATELY Cause: A parameter of encoder 1 was detected as being incorrect. It is possible that the parameterized encoder type does not match the connected encoder. The parameter involved can be determined as follows: - determine the parameter number using the fault value (r0949). - determine the parameter index (p0187). Fault value (r0949, interpret decimal): yyyyxxxx dec: yyyy = supplementary information, xxxx = parameter Supplementary information = 0: No information available. Supplementary information = 1: The component does not support HTL level (p0405.1 = 0) combined with track monitoring A/B <> -A/B (p0405.2 = 1). Supplementary information = 2: A code number for an identified encoder has been entered into p0400, however, no identification was carried out. Please start a new encoder identification. Supplementary information = 3: A code number for an identified encoder has been entered into p0400, however, no identification was carried out. Please select a listed encoder in p0400 with a code number < 10000. Supplementary information = 4: This component does not support SSI encoders (p0404.9 = 1) without track A/B. Supplementary information = 5: For the SQW encoder, the value in p4686 is greater than that in p0425. Supplementary information = 6: The DRIVE-CLiQ encoder cannot be us ed with this firmware version. See also: p0491 (Motor encoder fault response ENCODER) Remedy: - check whether the connected encoder type matc hes the encoder that has been parameterized. - correct the parameter specified by the fault value (r0949) and p0187. - re parameter number 314: Check the pole pair number and measuring gear ratio. The quotient of the "pole pair number" divided by the "measuring gear ra tio" must be less than or equal to 1000 ((r0313 * p0433) / p0432 <= 1000).
