コード 26002: Axis %1 encoder %2 parameterization error: number of encoder marks

問題の説明と安全警告

Siemens SINUMERIK 840D CNC は重大な Axis %1 encoder %2 parameterization error: number of encoder marks アラームをトリガーしました。製造サイクル中に機器への二次的損傷や部品の破損を防ぐために、資格のあるオペレーターまたはメンテナンス技術者による直ちの対応が必要です。電気キャビネットにアクセスする前に、必ず標準の安全およびLOTO手順が遵守されていることを確認してください。

公式トラブルシューティング手順

Parameters: %1 = Axis name, spindle number %2 = Encoder number Definitions: 1. Rotary measuring system (MD31000 $MA_ENC_IS_LINEAR[]==FALSE) The number of encoder marks set in MD31020 $MA_E NC_RESOL[] does not correspond to the value in the drive machine data (SIMODRIVE 611D: MD1005 $MD_ENC_RESOL_MOTOR; PROFIdrive: p979) or zero has been entered in one of the two machine data. 2. Absolute measuring system with EnDat interface (MD5790 $MD_ENC_TYPE[]==4) On absolute encoders, the resolution of the incremen tal and absolute tracks s upplied by the drive is also checked for consistency. For PROFIdrive drives: Compare drive parameter p979 (and possibly other internal drive, manufacture-specific parameters stated in the relevant drive documentation) Reaction: Mode group not ready. The NC switches to follow-up mode. Channel not ready. NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm. Channel not ready. Remedy: Please inform the authorized personnel/service department. Adjust machine data. For absolute encoders, possibly pending drive alarms indicating encoder problems should be evaluated. They could be the cause of incorrect entries of MD1022 $MD_ENC_ABS_RESOL_MOTOR/MD1032 $MD_ENC_ ABS_RESOL_DIRECT, which the drive reads out of the encoder itself. Program Continuation: Switch control OFF - ON.
