UFC092A V1 HIEE300686R1工控DCS系统备件
特定项目
有关20COMMD设置、配置、I/O消息传递和显式消息传递的详细信息，请参阅用户手册。技术信息20COMMD设备必须是v1.005固件或更高版本，才能与PowerFlex 700S一起使用。逻辑命令和逻辑状态是16位加上16位焊盘字，总共32位数据。逻辑命令字的位定义遵循与参数158[驱动逻辑Rslt]相同的模式。逻辑状态字的位定义遵循与参数155[逻辑状态]的位015相同的模式。参考、反馈和数据链接是32位数据。这意味着仅启用逻辑命令/状态和速度参考/Fdbk I/O，20COMMD将映射DeviceNet扫描仪中的8字节I/O。
逻辑命令/状态
速度参考/Fdbk和所有数据链路启用的情况下，20电机RPM（参数4）减速时间（参数33）减速率（RPM/sec）=自动化出版物PFLEXRM002DENE2013年8月37详细驱动配置和操作第1章COMMD将在DeviceNet扫描仪中映射总共40字节的I/O。显示了ControlLogix系统的I/O映像表。1速度参考作为双整数进入20COMMD。PowerFlex 700S固件自动将速度参考转换为浮点，因此参数20[speed Ref DPI]为浮点值。只有参数155[逻辑状态]的1位015出现在ControlLogix控制器的输入图像表中。2从PowerFlex 700S发送到20COMMD的速度反馈不受参数73[Spd Fdbk Scale]的影响。此外，PowerFlex 700S自动将参数72[Scaled Spd Fdbk]（浮点参数）转换为双整数，然后将值传输到20COMMD。
Specific items
For more information about 20COMMD setup, configuration, I/O messaging, and explicit messaging, see the user manual. Technical Information20The COMMD device must be v1.005 firmware or later to be used with PowerFlex 700S. The logic command and logic status are 16 bits plus 16 bit pad word, with a total of 32 bits of data. The bit definition of the logic command word follows the same pattern as parameter 158 [drive logic Rslt]. The bit definition of the logic status word follows the same pattern as bit 015 of parameter 155 [logic status]. Reference, feedback, and data links are 32-bit data. This means that only logical command/status and speed reference/Fdbk I/O is enabled, and 20COMMD will map the 8-byte I/O in the DeviceNet scanner.
Logic command/status
With speed reference/Fdbk and all data links enabled, 20 motor RPM (parameter 4) deceleration time (parameter 33) deceleration rate (RPM/sec)=automation publication PFLEXRM002DENE August 37, 2013 Detailed drive configuration and operation Chapter 1 COMMD will map a total of 40 bytes of I/O in the DeviceNet scanner. Shows the I/O image table for the ControlLogix system. 1 The speed reference enters 20COMMD as a double integer. The PowerFlex 700S firmware automatically converts the speed reference to a floating point, so the parameter 20 [speed Ref DPI] is a floating point value. Only 1 bit 015 of parameter 155 [logic state] appears in the input image table of ControlLogix controller. 2 The speed feedback sent from PowerFlex 700S to 20COMMD is not affected by parameter 73 [Spd Fdbk Scale]. In addition, PowerFlex 700S automatically converts parameter 72 [Scaled Spd Fdbk] (floating point parameter) to a double integer, and then transfers the value to 20COMMD.
