LAM 810-800081-014  数控系统

产品概述：

810-800081-015手动—在最大位置dflt=false（仅限瞬时真指令）指示达到最大位置的指令。这设置了所有位置需求信号的100%（最大）位置。调整和测试执行器动态执行器动态在配置模式中设置，但也可以在调整用户停止模式中进行调整。只有一个可调节的动力学参数，即执行机构惯性设置（见表9-1）。810-800081-015若要更改此参数，必须启用“用户停止”模式。执行机构惯性测试一旦更改，建议测试设置。可以通过选择“Actr Inertia Test Execute”（主动惯性测试执行）命令进行快速稳定性检查。这提供了一个短的执行机构定位序列，可用于验证惯性设置。该顺序进入30%行程3秒钟，然后进入70%行程3秒钟并返回30%行程3秒，结束测试。如果检测到不稳定，810-800081-015可以通过将Execute命令设置回false来中止测试。通常，如果惯性设置过高，输出将具有高频振荡，而过低，振荡频率将慢得多，810-800081-015或者响应将迟缓。

Auto Status（自动状态）——自动用户停止程序的字符串指示1=失败0=禁用1=启用2=寻找最小停止3=寻找最大停止4=停止设置自动状态Int——810-800081-015自动状态字符串的整数指示（见上文）。手动启用dflt=false命令启用手动用户校准。当为true时，手动设定位置（%）将主动控制驾驶员输出至指令位置。此模式也可用于笔划输出。手动设置位置（%）默认为50%（-10到110）手动位置需求。810-800081-015当启用手动模式时，此需求设置处于活动状态。可用于设置止动器和冲程执行器输出。手动状态——手动用户停止程序的字符串指示1=失败0=禁用1=启用2=最小停止集3=最大停止集手动状态Int——手动状态字符串的整数指示（见上文）。810-800081-015手动—在最小位置dflt=false（仅限瞬时真指令）指示达到最小位置的指令。这将为所有位置需求信号设置0%（最小）位置。

  A quick stability check can be done by selecting the ‘Actr Inertia Test Execute’ command. This provides a short actuator positioning sequence and can be used to verify the Inertia Setting.810-800081-015 The sequence goes to 30 % travel for 3 seconds, then goes to 70 % for 3 seconds and back to 30 % for 3 seconds,810-800081-015 concluding the test. If instability is detected, the test can be aborted by setting the Execute command back to false. In general,810-800081-015 if the Inertia Setting is too high the output will have a high frequency oscillation and too low the frequency of oscillation will be much slower or response will be sluggish.

  Manual—At Min Posn dflt = false (momentary true command only) Command to indicate minimum position is reached. This sets the 0 % (min) position for all position demand signals. Manual—At Max Posn dflt = false (momentary true command only) Command to indicate maximum position is reached. This sets the 100 % (max) position for all position demand signals.810-800081-015 Adjusting and Testing Actuator Dynamics Actuator dynamics are set in the Configure Mode, but can also be adjusted in the Adjust User Stop mode. There is only one adjustable dynamics parameter, it is the Actuator Inertia Setting810-800081-015 (see Table 9-1). To change this parameter, the User Stop mode must be enabled. Actuator Inertia Test Execute Once changed,810-800081-015 it is recommended the setting be tested.

Auto Status—String indication of the automatic user stop procedure.810-800081-015 –1= Failed 0 = Disabled 1 = Enabled 2 = Looking for Min Stop 3 = Looking for Max Stop 4 = Stops Set Auto Status Int—Integer indication of the Auto Status string (see above). Manual Enable dflt = false Command to enable the manual user calibration. When true, the Manual Set Position (%) is actively controlling the driver output to the commanded position. This mode can also be used to stroke the output.810-800081-015 Manual Set Position (%) default 50 % (–10 to 110) Manual position demand. This demand setting is active when the Manual Mode is enabled. Can be used to both set the stops and to stroke the actuator output. Manual Status—String indication of the manual user stop procedure.810-800081-015 –1= Failed 0 = Disabled 1 = Enabled 2 = Min Stop Set 3 = Max Stop Set Manual Status Int—Integer indication of the Manual Status string (see above).
