1394C-AM50-IH交流伺服控制器轴模块
标准模式（所有电源模块通用）z瞬时电源故障检测-即使电源瞬时故障持续时间不超过20毫秒（未检测到的瞬时电源故障），系统仍会继续运行而不会中断如果发生超过20毫秒的电源故障，控制器可能会也可能不会识别瞬时电源故障情况，因为存在不确定性。当控制器检测到瞬时电源故障时，它会暂停程序执行，同时保持其输出的当前状态。它还将瞬时电源故障发生的日期和时间记录到CPU的错误日志文件中。当电源恢复时，控制器恢复程序的执行。z电源故障检测当CPU工作电压（+5V）低于额定电压的95%时，控制器停止运行，关闭输出，然后打开故障触点。（关于FAIL触点如何工作的详细信息，请参阅第A2.3节）。z自动恢复当电源从瞬时电源故障状态恢复，CPU工作电压（+5V）上升到额定电压的95%以上时，控制器自动恢复正常操作。检测到电源故障后，控制器以重置重新启动模式重新启动。
即时检测模式
（当使用F3PU10-0N、F3PU10-10S、F3PU20-0N、F3PU20-0S、F3PU30-0N或F3PU30-0S时）z瞬时电源故障检测-即使电源瞬时故障持续时间不超过10ms（未检测到的瞬时电源故障），系统仍会继续运行，不会中断如果发生超过10 ms小于25 ms的电源故障，控制器可能会识别或不识别瞬时电源故障情况，因为存在不确定性。当控制器检测到瞬时电源故障时，它保持或重置其输出（根据停止时设置的输出），暂停程序执行，然后打开FAIL触点。（有关FAIL触点工作原理的详细信息，请参阅本手册第A2.3节）。它还将瞬时电源故障发生的日期和时间记录到CPU的错误日志文件中。检测到瞬时电源故障后，控制器以重置重启模式重新启动控制器始终检测任何超过25毫秒的瞬时功率损失情况。z电源故障检测当CPU工作电压（+5V）低于额定电压的95%时，控制器的整个功能被禁用。z自动恢复当电源从瞬时电源故障状态恢复，CPU工作电压（+5V）上升到额定电压的95%以上时，控制器自动恢复正常操作。检测到电源故障后，控制器以重置重启模式重新启动。
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.
