注②：表中初始状态栏中的“常开”、“常闭”不是继电器的触点状态，而是指继电器线圈是否得电。
“常闭”指控制器上电后继电器线圈立即得电工作，“常开”指控制器上电后继电器线圈不得电。
保护模式下，A继电器的触点（14#/15#）为常闭接点，一般串联在电动机控制接触器线圈回路中，但当控制器上电正常工作时，A继电器立即得电吸合，仅在失电或发生故障保护后方再次断开。
漏电时，接地保护功能自动退出。
②控制器不带通讯功能时型号为ST501，增选通讯功能时型号为ST502（Profibus-DP），ST503（Modbus-RTU）3、控制器保护模式下的典型接线图器才自动闭合，允许电机再次起动运行。
保护模式下控制器提供装置失电/自诊断、故障跳闸等故障接点输出（图中19、20、21），其中自诊断接点为常闭，控制器得电正常工作时为常开，当控制器自检到装置故障或失电时变为常闭。
故障跳闸接点为常开，只有当控制器检测到故障并按规定特性保护动作时变为常闭。
分析排除故障后需按复位按钮方可清除故障指示和故障接点信号。
保护模式下控制器可据用户需要增选电压功能、电动机绕组热保护功能、漏电保护功能、4～20mA模拟量输出功能、通讯功能等。
ST500智能型电动机控制器(直接启动模式)使用说明1、ST500控制器端子功能说明2、控制器的应用电动机的综合保护、测量功能、各种控制功能由ST500完成；参数显示、参数设定、报警、故障、管理信息查询等功能由ST522完成。
当控制器上电时，首先通过控制器检测CJ接触器是否在释放状态，如果接线不正确控制器报“接线错误”；如果接线正确时控制器ST522显示“起动准备就序”缺省信息窗口。
当ST500接收到起动命令时，ST500内部A继电器吸合，则CJ接触器得电吸合，控制器检测到CJ吸合，起动过程中“起动”灯亮，ST522显示“正在起动”进程状况，表示电动机在起动过程中。
起动结束后“起动”灯熄灭，ST522显示“正在运行”的缺省窗口。
停车时，ST500内部A继电器分开，CJ接触器释放，主回路断开，电动机停车。
3、ST522显示模块在保护方式下，ST522操作显示模块和ST500控制器配合使用(通过T9**—02串口线连接)，是ST500的可选部件之—，通过ST522可以实时显示电动机的各种测量参数；调整各种参数(保护定值、起动参数、系统参数)；查询各种故障信息／报警信息／DI和D0状态；检测各种管理信息。
直接起动模式下ST522面板功能定义如下：3.1 指示灯“停车”指示当前电动机为停车状态。
“起动”指示电动机的停车和运行的中间状态，包括起动和转换过程。
“运行”指示当前电动机处于正常工作状态。
“报警”指示灯点亮时表示有非跳闸故障报警发生。
“故障”闪烁表示有跳闸故障，当前在处理过程中；恒亮表示当前处于故障跳闸状态。
3.2 功能键“起动A”在本地权限下，此按键可以控制电动机起动运行。
该控制按键据需要可锁定不用。
“停车”在本地权限下，此按键可以控制运行电动机停车。
该控制按键据需要可锁定不用。
“复位”清除故障显示，退出故障跳闸状态，但不能清除热容。
“返回”、“确认”“↑”、“↓”四个功能键用于参数设定和参数查询。

Controller simulates heat capacity under various run status, timely monitor the heat condition of motor, effectively protect restart under overheatcondition ，can make use of the motor atmaximum degree ，also can ensure the motor ’s safety ，ensure the continuous run of motor. Below chart is the heat capacity when frequently start ，only when the heat capacity cool to the “ forbid ” line, can send the wellprepared signal ， allow to start the motor again. start allowing heat capacity （heat capacity on “forbid ” line ） is divided two kinds ，one is the fixed heat capacity is15%（the 1st way ）；the other heatcapacity only needs to satisfy（100%-heat capacity produced by last time start-2%） or 15% （ the 2nd way ）.Note ：in special condition, to make the motor continues run ，can forcedly clear the heat capacity in memory, immediately start the motor, this function need ST500 series controller support.Overburden failure resetAfter overburden failure switch off, provides automatic and manual two kinds reset ways for users to choose.“ automatic reset ”way is failure reset automatically after motor overburden failure switches off ，heat capacity reduces to below allowing start heat capacity ，not need to through reset operation can start again ；“ manual reset ”way is failure cannot be cleared automatically, need to manual reset, otherwise not allow to start motor.Set rangeProtection actuating way switch /alarmCurve speed K 18 kind for choose Cool time 0min ～1080min Failure reset way manual/automaticStart allowing heat capacity the 1st way 、the 2nd way Cool-heat curve ratio 20%～100%characteristicwhen motor runs under the overburden failure, controller computes the heat capacity I 2t according to the heat characteristic of motor, simulate motor heat characteristic to protect the motor.

Phase breaking is the limited status of imbalance, imbalance rate when phase break is1 100%，production immediately actuate the protection. The computing formula of imbalance rate: |I-Iav|/Iav，Iav is the average value of three phase，when Iav is below to Ir1，the denominator use Ir1.When the motor happens phase lacking or three phase imbalance, protection to 5DO relay.

附录一ST500智能马达控制器的使用说明书(保护模式)(2003年)苏州智能配电自动化有限公司目录1、控制器的面板及端子功能说明 (1)2、控制器的功能配置一览表 (2)3、控制器应用接线图 (3)4、ST522显示模块 (3)5、控制器的使用说明 (4)5.1 控制器的主要功能 (5)5.2 控制器的参数测量功能 (5)5.3 控制器的报警查询功能 (5)5.4 控制器的故障查询功能 (6)5.5 控制器的维护管理功能 (6)5.6 控制器的输入输出状态查询功能 (7)5.7 控制器的各种保护定值设置功能 (7)5.8 控制器的系统参数设置功能 (16)1、控制器面板及端子标准配置复位”功能按钮或控制器断电一次则可清除热容量，允许立即起动电机。
注②：表中初始状态栏中的“常开”、“常闭”不是继电器的触点状态，而是指继电器线圈是否得电。
“常闭”指控制器上电后继电器线圈立即得电工作，“常开”指控制器上电后继电器线圈不得电。
保护模式下，A继电器的触点（14#/15#）为常闭接点，一般串联在电动机控制接触器线圈回路中，但当控制器上电正常工作时，A继电器立即得电吸合，仅在失电或发生故障保护后方再次断开。
漏电时，接地保护功能自动退出。
②控制器不带通讯功能时型号为ST501，增选通讯功能时型号为ST502（Profibus-DP），ST503（Modbus-RTU）3、控制器保护模式下的典型接线图器才自动闭合，允许电机再次起动运行。
保护模式下控制器提供装置失电/自诊断、故障跳闸等故障接点输出（图中19、20、21），其中自诊断接点为常闭，控制器得电正常工作时为常开，当控制器自检到装置故障或失电时变为常闭。
故障跳闸接点为常开，只有当控制器检测到故障并按规定特性保护动作时变为常闭。
分析排除故障后需按复位按钮方可清除故障指示和故障接点信号。
保护模式下控制器可据用户需要增选电压功能、电动机绕组热保护功能、漏电保护功能、4～20mA模拟量输出功能、通讯功能等。
