ABB UFC921A101 3BHE024855R0101 系统备件
完成示教要完成示教过程，请按住示教按钮，直到状态指示器D14熄灭（约5秒），这表示示教过程结束。功能描述-RS-485通信型号图6-RS-485控制单元扩展PCB引脚列表表17中描述了与RS-485控制器型号一起使用的主连接器J2上的引脚分配。表18描述了连接器J16的连接，即位于扩展PCB上的RS-485连接。图7提供了与每个RS-485输入相关的阻抗的附加信息。图7-RS-485端子输入示意图重要信息如果您想删除新设置（以恢复先前存储的值），而不是按住示教按钮，请短按示教按钮。状态指示器D14熄灭（表示示教过程结束），恢复先前的值。表17-J2引脚列表引脚信号说明备注1 0V DC电源-2+24V DC电源-3接地-4未连接未连接-5输入2触发和保持参见出版物10000071139 6输入1未使用7输出2灯阵列中断（1）（1）或超高（特殊功能）0V DC=中断24V DC=未中断8输出1悬垂24V DC=无悬垂表18-J16引脚列表引脚2导线4导线1 0V DC 0V DC 2-Rx+3屏蔽屏蔽4-Rx5 B Tx+6 A TxPNP D7 LED-电源RS485扩展PCB D3 输出1 D4 LED输出2 D9错误D8 Com Tx D6 LED输入2 D5 LED输入1 RJ45连接器发射器RJ45连接器接收器D2 LED D1 LED槽2槽1可拆卸弹簧加载连接器S1 J2 J12 J13 S2输出1输出2输入1输入2 n.c.接地。24 VDC 0 VDC In 2 PNP NPN PNP NPN-In 1输入逻辑跳线In 2 PNN NPN PNN NPN-In 2输入逻辑跳线B A RS-485驱动器135欧姆罗克韦尔自动化出版物45MLA-IN002C-EN-P-2020年8月9 45MLA控制器安装说明状态指示器表19显示了RS-485扩展PCB上状态指示器D8和D9的含义。
Complete teaching To complete the teaching process, press and hold the teaching button until the status indicator D14 goes out (about 5 seconds), which indicates that the teaching process is over. Function Description - RS-485 Communication Model Figure 6-RS-485 Control Unit Extended PCB Pin List Table 17 describes the pin assignment on the main connector J2 used with the RS-485 controller model. Table 18 describes the connection of connector J16, that is, the RS-485 connection on the expansion PCB. Figure 7 provides additional information about the impedance associated with each RS-485 input. Figure 7-RS-485 Terminal Input Diagram Important Information If you want to delete the new settings (to restore the previously stored values) instead of pressing and holding the Teach button, briefly press the Teach button. The status indicator D14 goes out (indicating the end of the teaching process) and restores the previous value.
