產(chǎn)品概述：
810-800081-013 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(nèi)低于“Fail Min”810-800081-013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(nèi)高于“Fail Max”占空比水平，則確定為故障。PwmIn Fail Delay（sec）default=0.1 sec（0.01到10）PWM輸入故障延遲（以秒為單位）。810-800081-013 PwmIn濾波器默認(rèn)值=PWM輸入上的0.01（0到1）滯后τ濾波器調(diào)整。停止——最小停止偏移（度）默認(rèn)值=0.5度（-10到10）旋轉(zhuǎn)角度的電氣停止調(diào)整。這是在最小輸出位置時額外“偏置”的執(zhí)行器范圍調(diào)整設(shè)置。810-800081-013 該值使總體0%的需求位置存在偏差。當(dāng)為正時，此設(shè)置可通過有效地將最小止動位置移動到離機(jī)械止動器更遠(yuǎn)的位置（另請參閱“維修硬件調(diào)整”選項卡頁上的“電流限制-最小止動”），幫助防止ProAct控件的當(dāng)前驅(qū)動器在達(dá)到止動器時將執(zhí)行器驅(qū)動到硬止動器（機(jī)械限制）。將此參數(shù)設(shè)置為負(fù)值將迫使輸出電流更難驅(qū)動至機(jī)械止動器810-800081-013 ，以確保閥門關(guān)閉。另請參閱維修模式中的調(diào)整用戶停止部分。
位置誤差最大值（%）810-800081-013 默認(rèn)值=10%（1.0到110）此設(shè)置是在發(fā)出位置誤差警報之前，位置需求與實際位置之間的最大差值（以百分比表示）。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。請注意，內(nèi)部進(jìn)行了一些過濾，以模擬預(yù)期的致動器響應(yīng)，810-800081-013 并最大限度地減少干擾警報。此設(shè)置適用于任何請求源、主源或備份。注：位置需求在內(nèi)部限制在0到100之間，810-800081-013 僅用于位置誤差檢測，以消除錯誤的位置誤差警報。位置誤差延遲（秒）默認(rèn)值=1秒（0.1到10）位置誤差延遲以秒為單位--請參閱位置誤差最大PwmIn Fail最小頻率（%）默認(rèn)值=85%標(biāo)稱頻率（50到99）值，在該值下PWM輸入將被確定為失敗。該設(shè)置表示為在配置模式中設(shè)置的標(biāo)稱頻率的百分比（即，標(biāo)稱1000 Hz的85%相當(dāng)于850 Hz的故障水平）。810-800081-013 如果PWM輸入頻率在“PwmIn Fail Delay”時間內(nèi)低于“Fail Min”赫茲水平，則確定故障。PwmIn Fail最大頻率（%）默認(rèn)值=額定頻率（101至150）值的115%，在該值下PWM輸入將被確定為故障。810-800081-013 該設(shè)置以配置模式中設(shè)置的標(biāo)稱頻率的百分比表示。如果PWM輸入頻率在“PwmIn Fail Delay”時間內(nèi)高于“Fail Max”赫茲水平，則確定為故障。
PwmIn Fail Delay (sec) default = 0.1 sec (0.01 to 10) PWM input failure delay in seconds. PwmIn Filter default = 0.01 (0 to 1) Lag-tau filter adjustment on the PWM input.810-800081-013 Stops—Min Stop Bias (deg) default = 0.5 degrees (–10 to 10) Electrical Stop adjustment in degrees of rotation. This is an actuator range adjustment setting for an extra “bias” when at the minimum output position. This value biases the overall 0 % demand position. When positive, this setting can help prevent the ProAct control's current driver from driving the actuator into the hard stops (mechanical limits) when the stop is reached by effectively moving the minimum stop position further from the mechanical stops (see also the Current Limit –810-800081-013 Min Stop on the Service Hardware Adjustments tab sheet). Setting this parameter to a negative value will force the output current to drive into the mechanical stop harder to ensure the valve is closed.810-800081-013 Refer also to the Adjust User Stops section in the Service Mode.
A failure is determined if the PWM input frequency is below the ‘Fail Min’ hertz level for the ‘PwmIn Fail Delay’ time.810-800081-013 PwmIn Fail Max Freq (%) default= 115 % of nominal freq (101 to 150) Value at which the PWM input will be determined as failed. The setting is expressed as a percentage of the nominal frequency set in the Configure Mode. A failure is determined if the PWM input frequency is above the ‘Fail Max’ hertz level for the ‘PwmIn Fail Delay’ time. PwmIn Fail Min Duty (%) default= 5 % (1 to 50) Duty cycle value at which the PWM input will be determined as failed. A failure is determined if the PWM input duty cycle is below the ‘Fail Min’810-800081-013 duty cycle level for the ‘PwmIn Fail Delay’ time. PwmIn Fail Max Duty (%) default= 95 % (50 to 99) Duty cycle value at which the PWM input will be determined as failed. A failure is determined if the PWM input duty cycle is above the ‘Fail Max’ duty cycle level for the ‘PwmIn Fail Delay’ time.810-800081-013
Position Error Max (%) default = 10 % ( 1.0 to 110) This setting is the maximum difference between the position demand and the actual position in percentage before a position error alarm will be issued.810-800081-013 The difference must exceed the ‘Error’ percentage value for the ‘Error Delay’ duration to generate an alarm. Note that there is some filtering done internally to model the expected actuator response and minimize nuisance alarms. This setting applies to any Demand source, primary or backup. Note: The position demand is limited internally between 0 and 100, for position error detection only, to eliminate false position error alarms.810-800081-013 Position Error Delay (sec) default = 1 sec ( 0.1 to 10) Position error delay in seconds—see Position Error Max. PwmIn Fail Min Freq (%) default= 85 % of nominal freq (50 to 99) Value at which the PWM input will be determined as failed. The setting is expressed as a percentage of the nominal frequency set in the Configure Mode (i.e. 85 % of a nominal of 1000 Hz would equate to a fail level of 850 Hz).810-800081-013
