1394C-AM50-IH交流伺服控制器軸模塊
標(biāo)準(zhǔn)模式（所有電源模塊通用）z瞬時電源故障檢測-即使電源瞬時故障持續(xù)時間不超過20毫秒（未檢測到的瞬時電源故障），系統(tǒng)仍會繼續(xù)運(yùn)行而不會中斷如果發(fā)生超過20毫秒的電源故障，控制器可能會也可能不會識別瞬時電源故障情況，因為存在不確定性。當(dāng)控制器檢測到瞬時電源故障時，它會暫停程序執(zhí)行，同時保持其輸出的當(dāng)前狀態(tài)。它還將瞬時電源故障發(fā)生的日期和時間記錄到CPU的錯誤日志文件中。當(dāng)電源恢復(fù)時，控制器恢復(fù)程序的執(zhí)行。z電源故障檢測當(dāng)CPU工作電壓（+5V）低于額定電壓的95%時，控制器停止運(yùn)行，關(guān)閉輸出，然后打開故障觸點。（關(guān)于FAIL觸點如何工作的詳細(xì)信息，請參閱第A2.3節(jié)）。z自動恢復(fù)當(dāng)電源從瞬時電源故障狀態(tài)恢復(fù)，CPU工作電壓（+5V）上升到額定電壓的95%以上時，控制器自動恢復(fù)正常操作。檢測到電源故障后，控制器以重置重新啟動模式重新啟動。
即時檢測模式
（當(dāng)使用F3PU10-0N、F3PU10-10S、F3PU20-0N、F3PU20-0S、F3PU30-0N或F3PU30-0S時）z瞬時電源故障檢測-即使電源瞬時故障持續(xù)時間不超過10ms（未檢測到的瞬時電源故障），系統(tǒng)仍會繼續(xù)運(yùn)行，不會中斷如果發(fā)生超過10 ms小于25 ms的電源故障，控制器可能會識別或不識別瞬時電源故障情況，因為存在不確定性。當(dāng)控制器檢測到瞬時電源故障時，它保持或重置其輸出（根據(jù)停止時設(shè)置的輸出），暫停程序執(zhí)行，然后打開FAIL觸點。（有關(guān)FAIL觸點工作原理的詳細(xì)信息，請參閱本手冊第A2.3節(jié)）。它還將瞬時電源故障發(fā)生的日期和時間記錄到CPU的錯誤日志文件中。檢測到瞬時電源故障后，控制器以重置重啟模式重新啟動控制器始終檢測任何超過25毫秒的瞬時功率損失情況。z電源故障檢測當(dāng)CPU工作電壓（+5V）低于額定電壓的95%時，控制器的整個功能被禁用。z自動恢復(fù)當(dāng)電源從瞬時電源故障狀態(tài)恢復(fù)，CPU工作電壓（+5V）上升到額定電壓的95%以上時，控制器自動恢復(fù)正常操作。檢測到電源故障后，控制器以重置重啟模式重新啟動。
Standard Mode (common to all power supply modules)
z Momentary Power Failure Detection - System operation continues without interruption even if the power fails momentarily for no longer than 20 ms (undetected momentary power failure). - If a power failure longer than 20 ms occurs, the controller may or may not recognize a momentary power failure condition because an uncertainty is involved. When the controller detects a momentary power failure, it suspends program execution while retaining the current state of its outputs. It also records the date and time at which the momentary power failure occurred into the error log file in the CPU. When power is restored, the controller resumes the execution of the program. z Power Failure Detection When the CPU operating voltage (+5V) falls below 95% of the rated voltage, the controller stops operation, turns off its outputs, and then turn on the FAIL contact. (Refer to Section A2.3 for details on how the FAIL contact works). z Automatic Recovery The controller resumes normal operation automatically when the power recovers from a momentary power failure condition and the CPU operating voltage (+5V) rises above 95% of the rated voltage. The controller restarts in the reset restart mode after a power failure is detected.
Immediate Detection Mode
(when F3PU10-0N, F3PU10-0S, F3PU20-0N, F3PU20-0S, F3PU30-0N or F3PU30-0S is used) z Momentary Power Failure Detection - System operation continues without interruption even if the power fails momentarily for no longer than 10 ms (undetected momentary power failure). - If a power failure longer than 10 ms and less than 25 ms occurs, the controller may or may not recognize a momentary power failure condition because an uncertainty is involved. When the controller detects a momentary power failure, it holds or resets its outputs (in accordance with the output set at stop) , it suspends program execution, and then it turns on the FAIL contact. (Refer to Section A2.3 of this manual for details on how the FAIL contact works). It also records the date and time at which the momentary power failure occurred into the error log file in the CPU. The controller restarts in the reset restart mode after a momentary power failure is detected. - The controller always detects any momentary power loss conditions that are longer than 25 ms. z Power Failure Detection The entire functionality of the controller is disabled when the CPU operating voltage (+5V) falls below 95% of the rated voltage. z Automatic Recovery The controller resumes normal operation automatically when the power recovers from a momentary power failure condition and the CPU operating voltage (+5V) rises above 95% of the rated voltage. The controller restarts in the reset restart mode following the detection of a power failure condition.
