在MICROMASTER 4 (MM4)和 SINAMICS G120 (CU2x0x)上显示用户想要的信息

问题: 怎样标定MM4 和 G120 驱动单元的显示, 以致于能看到想要的值? 回答: 在变频器上有两种方法显示用户想要的值. 当不使用PID调节器时,可以在MM420, MM430, MM440和G120 上显示 : P2264: 输入实际值 P2267 = 200% P2268 = -200% 可能显示负值的范围 P2269: 乘法器 r2272: 显示标定的值 P0003 = 3 P0005 = r2272 在 MM430, MM440 和G120 上的显示–用功能块选择: P2800 = 1 P2802.8 = 1 P2877.0: 实际值的输入 P2877.1 = 2889 P2889: 乘法器 P0003 = 3 P0005 = r2878 变频器的内部值范围在-200% 和 +200%之间, 例如,显示变速箱的输出速度. 如果要求更大的显示范围, 那么用户很可能得到不正确的数值. 范例 : 用 0,00...125.25标定0...50 Hz P2000 = 50 Hz P2264 = r0021 (or r0020) or P2877.0 = r0021 (or r0020) P2269 = 125.25 or P2889 = 125.25 P0005 = r2272 or P0005 = r2878 同样地,阅读应用文章ID: 24115770 „通过使用变频器的自由功能块显示变速箱的输出速度“. 编写: A&D SD CST 关键字: MM4, G120, 显示值, 标定 条目号:25341663 日期:2007-05-16 QUESTION: How can the displays of MM4 and G120 drive units be scaled so that a specific value can be shown? ANSWER: There are two ways to display a customer-specific value on a drive inverter. Display on the MM420, MM430, MM440 and G120 when the PID controller is not used: P2264: Input for the actual value P2267 = 200% P2268 = -200% for possible negative display values P2269: Multiplier r2272: Scaled display value P0003 = 3 P0005 = r2272 Display on MM430, MM440 and G120 – alternatively using function blocks: P2800 = 1 P2802.8 = 1 P2877.0: Input for the actual value P2877.1 = 2889 P2889: Multiplier P0003 = 3 P0005 = r2878 The internal value ranges for the drive inverter lie between-200% and +200%, e.g. output speeds of gearboxes can be displayed. If a larger display range is required, then the customer must accept an incorrect position of the decimal point. Example : Displaying 0...50 Hz as 0,00...125.25 P2000 = 50 Hz P2264 = r0021 (or r0020) or P2877.0 = r0021 (or r0020) P2269 = 125.25 or P2889 = 125.25 P0005 = r2272 or P0005 = r2878 Also read the application Article ID: 24115770 „Displaying the speed after a gearbox using the free blocks of the drive inverter“.
