MM4 AOP错误消息“No Drive Responding”

问题： 什么是引发以下AOP错误消息的原因： “Drive Log on No Drive Responding P to acknowledge”? 解答： 这意味着AOP尝试连接到驱动器，但它对USS指令没有响应。 按P两次将会退出错误。用户应该确认变换器上设置的通信波特率与AOP上设置的一致。变换器参数P2010指数1应该设置为6，代表9600波特。 为了访问内部AOP参数，需要执行以下步骤。 1. 按照AOP操作指南第5节的第21页上所描述的步骤，将模式设置为”内部“。 2. 按照AOP操作指南第6节的第22页上所描述的步骤，选择”参数“。 3. 选择AOP参数设置。 4. 查看„All“参数。 5. 设置P0003 = 3 相关参数的缺省设置为： P8552，基本从站地址 = 0。 P8553，缺省波特率 = 6 (9600波特)。 P8554，使能自动波特率 = 0 (关闭自动波特率)。 这些设置将保证驱动器和AOP之间的通信正确工作。 编写: Andy Hawkings A&D SD CST 适用: MM4 AOP #Ende# -------------------------------------------------------------------------------- © Siemens AG, 1998, 2000 条目号:22279833 日期:2006-06-15 QUESTION: What is the cause of the AOP error message: "Drive Log on No Drive Responding P to acknowledge"? ANSWER: This means the AOP is attempting to connect to the drive, but it is not responding to the USS commands. Pressing P twice will quit the error.The user should confirm that the communication baud rate set on the inverter is the same as that which is set on the AOP. Inverter parameter P2010 index 1 should be set to 6 which is 9600 baud. For access to the internal AOP parameters, the following procedure must be performed. 1. Set mode to „Internal“ as described in Section 5 on Page 21 of the AOP Operating Instructions. 2. Select „Parameters“ as described in Section 6 on Page 22 of the AOP Operating Instructions. 3. Select the AOP Parameter Set. 4. View „All“ Parameters. 5. Set P0003 = 3 The default settings of the relevant parameters are: P8552, Base Slave Address = 0. P8553, Default Baud Rate = 6 (9600 baud). P8554, Enable Autobaud = 0 (autobaud off). These settings should enable the communications between the drive and AOP to function correctly Written by: Andy Hawkings A&D SD CST Applies to: MM4 AOP Entry ID:22279833 Date:2005-11-09
