LAM 810-017003-004 集成電路
產品概述:
故障可能是can過慢或can無信號,具體取決于接收到的信息數量。CAN輸入故障延遲(秒)默認值=0.3秒(0.1到10)CAN請求信號故障延遲(以秒為單位)。該瞬態(tài)電流極限和穩(wěn)態(tài)電流都在最小或最大停止電流極限激活之前主動嘗試定位輸出——也就是說,在該極限接合之前,電流可能達到瞬態(tài)極限,然后是穩(wěn)態(tài)極限。這些設置僅在電流控制器上提供積分限制,因此實際電流可能超過此設置。高于此設置的當前誤差與位置誤差需求成比例。一旦達到最大(或最?。O限,如果需求繼續(xù)增加(或減少),電流也將按比例增加。瞬態(tài)和穩(wěn)態(tài)電流限制仍然有效——電流不會超過這些限制。需求跟蹤誤差(%)默認值=15%(1.0到100)當使用冗余需求輸入(主和備份)時,需求輸入的跟蹤誤差調整。此設置是在發(fā)出跟蹤警報之前,控制需求和備用需求之間的最大差值(百分比)。差值必須超過“錯誤延遲”持續(xù)時間的“錯誤”百分比值才能生成警報。值為“100”將禁用報警。請求跟蹤錯誤延遲(秒)默認值=1秒(0.1到10)跟蹤錯誤延遲,以秒為單位--請參閱請求跟蹤錯誤。
該設置以配置模式中設置的標稱頻率的百分比表示。如果PWM輸入頻率在“PwmIn Fail Delay”時間內高于“Fail Max”赫茲水平,則確定為故障。PwmIn Fail Min Duty(%)default=5%(1到50)Duty cycle value(占空比值),在該值PWM輸入將被確定為失敗。如果PWM輸入占空比在“PwmIn Fail Delay”時間內低于“Fail Min”占空比水平,則確定為故障。PwmIn Fail Max Duty(%)default=95%(50到99)Duty cycle value(占空比值),在該值PWM輸入將被確定為失敗。如果PWM輸入占空比在“PwmIn Fail Delay”時間內高于“Fail Max”占空比水平,則確定為故障。
Auto Status—String indication of the automatic user stop procedure. –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. 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. –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). 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. 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 Setting (see Table 9-1).
To change this parameter, the User Stop mode must be enabled. Actuator Inertia Test Execute Once changed, it is recommended the setting be tested. 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. The sequence goes to 30 % travel for 3 seconds, then goes to 70 % for 3 seconds and back to 30 % for 3 seconds, concluding the test. If instability is detected, the test can be aborted by setting the Execute command back to false. In general, 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.
Actuator Inertia Setting dflt =0 (range 0–25) Actuator/valve inertia setting. This setting is available for systems with higher or lower inertia than the default as indicated by excessive shaft movement. A zero (0) setting is basically for an unconnected shaft, whereas, increasing the setting implies a higher inertia in the system. Refer to Table 9-1 for an approximate Inertia Setting value based on lever size. High Friction System dflt =false (false, true) Internal Disturbance Observer Controller (dobs) Enable command. Normally set to false, only needed in high friction systems. As a general rule-of-thumb, when more than 2 A of current are required to move the actuator then a true setting will help with controllability.
