コード SEAL-021: Gun on/off too late: Sch %d

問題の説明と安全警告

Fanuc R-30i Series Robot Controller は重大な Gun on/off too late: Sch %d 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

Cause: In the Schedule number listed, the Gun On signal has been set up to turn on or off too long after the node the SS[] or SE is attached to. Currently, if this signal is set up to turn on or off greater than 100ms after the node, this warning will be posted and the signal will fore 100ms after the node. These are the formulas used to determine when the gun will be turned on or off relative to the node for seal schedule 'n': For SS[n]: Time_Before = EQUIPMENT_DELAY - GUNON_DELAY For SE: Time_Before = EQUIPMENT_DELAY - GUNOFF_DELAY Note that a NEGATIVE Time_Before means AFTER the node. Remedy: There is no real danger in this condition. You should be aware that if you try to turn the gun on or off after 100ms AFTER the node, the signal will always be fired 100ms after the node and this warning will be posted. To correct this problem, make the equipment_delay more positive or the gunon/gunoff delay more negative, to move the firing of the signal up earlier.
