PFCL 201CD-50.0控制卡件
由静电产生的静电会损坏各种驱动板上的互补金属氧化物半导体器件。建议您执行这些步骤，以防止在拆除或安装电路板时发生此类损坏。•佩戴与底盘接地的手腕式接地带。•在将新电路板从导电包中取出之前，连接腕带。•从驱动器中取出电路板，并立即将其插入导电包中。故障描述故障显示LCD显示屏用于通过显示与故障相关的简短文本陈述来指示故障，如下图所示。在启动“清除故障”或循环驱动电源之前，将显示故障。A系列（版本3.0）或B系列及以上HIM在发生故障时将显示故障，无论显示器处于何种状态。此外，通过从控制状态菜单中选择“故障队列”，可以显示过去故障的列表（更多信息，请参阅1336 PLUS II用户手册的第3章）。有关各种故障的列表和说明，请参阅表3.A。图3.1故障显示清除故障当发生故障时，必须先排除故障原因，然后才能清除故障。采取纠正措施后，只需循环驱动电源即可清除故障。如果｛Flt clear Mode｝参数设置为“Enabled”（启用），则从HIM或控制接口选项（TB3）发出有效的停止命令也将清除故障。此外，可以随时从串行设备（如果连接）发出“清除故障”命令. ! 注意：该组件包含对静电放电敏感的零件和子组件。维修该组件时，需要采取静态控制预防措施。如果忽略静电放电控制程序，可能会导致部件损坏。如果您不熟悉静电控制程序，请参考Allen-Bradley出版物8000-4.5.2《防静电放电》或任何其他适用的ESD保护手册。1336 PLUS II-6.16-2001年9月故障排除和错误代码3-3触点说明触点CR1-CR4的示意图如1336 PLUSII用户手册的图2-5所示。通电后，这些触点将改变状态。例如：在正常操作条件下（无故障，驱动器运行），TB2-13和14处的CR3触点（默认固件设置）断开，TB2-14和15处的触点闭合。当发生故障时，这些触点的状态将发生变化。表3.A 1336 PLUS II故障描述名称和故障#描述动作Adptr Freq Err 65所选频率参考的SCAN端口适配器向驱动器发送的频率大于32767。纠正导致SCAN端口适配器向驱动器发送非法频率参考的问题。辅助故障02辅助输入联锁打开。如果安装了控制接口选项，请检查TB3连接。如果未安装，请将[输入模式]设置为“状态”
generated by static electricity can damage the complimentary metallic oxide semiconductor devices on various drive boards. It is recommended that you perform these procedures to guard against this type of damage when circuit boards are removed or installed. • Wear a wrist type grounding strap that is grounded to the chassis. • Attach the wrist strap before removing the new circuit board from the conductive packet. • Remove boards from the drive and immediately insert them into their conductive packets. Fault Descriptions Fault Display The LCD display is used to indicate a fault by showing a brief text statement relating to the fault as shown in the following figure. The fault will be displayed until “Clear Faults” is initiated or drive power is cycled. A Series A (version 3.0) or Series B & up HIM will display a fault when it occurs, no matter what state the display is in. In addition, a listing of past faults can be displayed by selecting “Fault queue” from the Control Status menu (See Chapter 3 of the 1336 PLUS II user manual for more information). Refer to Table 3.A for a listing and description of the various faults. Figure 3.1 Fault Display Clearing a Fault When a fault occurs, the cause must be corrected before the fault can be cleared. After corrective action has been taken, simply cycling drive power will clear the fault. Issuing a valid Stop command from the HIM or Control Interface option (TB3) will also clear a fault if the {Flt Clear Mode] parameter is set to “Enabled”. In addition, a “Clear Faults” command can be issued anytime from a serial device (if connected). ! ATTENTION: This assembly contains parts and sub-assemblies that are sensitive to electrostatic discharge. Static control precautions are required when servicing this assembly. Component damage may result if you ignore electrostatic discharge control procedures. If you are not familiar with static control procedures, reference Allen-Bradley Publication 8000-4.5.2, Guarding Against Electrostatic Discharge, or any other applicable ESD protection handbook. 1336 PLUS II - 6.16 - September, 2001 Troubleshooting and Error Codes 3-3 Contact Description A schematic representation of contacts CR1-CR4 is shown in Figure 2-5 of the 1336 PLUS II User Manual. When powered these contacts will change state. For Example: During normal operating conditions (no faults present, drive running), the CR3 contacts (default firmware setting) at TB2-13 & 14 are open, and the contacts at TB2-14 & 15 are closed. When a fault occurs, the state of these contacts will change. Table 3.A 1336 PLUS II Fault Descriptions Name & Fault # Description Action Adptr Freq Err 65 The SCANport adapter that was the selected frequency reference sent a frequency greater than 32767 to the drive. Correct the problem that is causing the SCANport adapter to send the illegal frequency reference to the drive. Auxiliary Fault 02 The auxiliary input interlock is open. If Control Interface option is installed, check TB3 connections. If not installed, set [Input Mode] to “Status.”
