PFEA 111-65工控备件
LogicCommand[LogicCmd]内部变量:非编程终端:位字段描述:当编程终端受驱动器控制时,此控件驱动逻辑操作。所有函数都与LogicCommand相同。如果设置了逻辑命令中的Command/Enable位,则逻辑命令中将选择Drivecontrolwithlogicalcommand(带逻辑命令的驱动控制),而不考虑其他逻辑字中Command/Enabled位的状态。逻辑命令中停止位与逻辑命令字中停止位逻辑或。参数–VelocityReferenceFraction[VelRefFraction]Internallunits:=ffffh=基本电机速度/编程终端单位:无描述:当在逻辑命令字中选择了外部速度控制时,此字提供外部速度参考的分数部分。此字中包含的数据表示速度参考的低阶分数部分。电机基本速度值始终与以下数字表示形式一致:ParmParm+/-,当指定外部速度参考时,使用该参数可以提供一种倾向的解决方案。请注意,有效值等于/等于参考单位参数。同样,等效值等于/或参考单位参数,并且ffffhis等效值等于或等于参考单位。通过这种方式,可以将Parameter作为指定一个速度参考单位的额外分数的方法。如果不需要分数解,则Parameter不应被链接,其值将默认为零。参数–VelocityReferenceWhole[VelRefWhole]Internallunits:=h=pu=基本电机速度编程终端单位:RPM说明:当在逻辑命令字中选择外部速度控制时,此字提供外部速度参考的整数部分。此字中包含的数据表示制造速度参考的高阶整数部分。第章编程参数参数–转速[转速]内部参数:=h=pu=基础电机速度编程终端设备:RPM说明:该词提供了使用速度计时的电机速度反馈信号。该输入通常与来自Discrete适配器板的模拟输出参数相关联。应设置头部适配器的模拟比例,以使该参数的值表示基础电机速度。当速度反馈使用转速时,反馈设备类型Parm中必须存在“”。参数–TorqueReference[TorqueReference]Internallunits:=h=pu=%rated电机扭矩编程终端单位:百分比电机扭矩描述:此词提供外部电机扭矩参考到驱动器。可通过将TorqueModeParm设置为值“”来选择外部扭矩参考。当ProcessTrimSelectParm包含值“”时,外部或查询参考可以通过汇总ProcessTrim输出进行修改。当“最小”或“最大”时,也可以使用外部或查询输入
