n速度測量調整調試步驟
在調試過程中,是否調整步進速度-是,電機將在首次確認啟動后轉動
驅動-在EMF模式下按(I)12.5%的基準
速度(1.05)或模擬轉速表或編碼器模式基本速度的25%(1.05)。
如果此速度太高,無法進行首次應用檢查不要使用此調試步驟!
現(xiàn)在退出調試向導并執(zhí)行此操作
首先,使用操作系統(tǒng)通過本地控制進行檢查
面板DCS400PAN。請參閱第6.1章面板
模式:驅動控制。之后,再次啟動調試向導,提示速度控制器自動調整
只有成功調試的自調整才會更改速度控制器的參數(shù):速度調節(jié)器KP(5.07)和速度調節(jié)TI(5.08),其他參數(shù)保持不變。自整定后,必須在低速下檢查驅動器的性能。
在自整定過程中,電機加速兩次,最多兩次額定速度的80%。應用程序必須允許,如果沒有,則不得進行自整定。在某種程度上應用程序將禁止自動調諧的情況。
什么允許自調整:
?電機與負載解耦
?電機+皮帶傳動
?電機+齒輪箱
?電機+10%負載應用
抑制自調諧的因素:
?振蕩負載
?滿載/過載
?高慣性(導致反應時間長)
不建議在以下情況下開始自調諧:
?起重機/電梯(自整定不考慮電梯高度)n速度自動調諧失敗
如果在調試向導期間自動調整失?。?br/>
?按下以下位置的菜單按鈕重置報警:操作面板。
?按ENTER鍵,并按照調試向導進行操作直至結束。
?完成向導后,速度控制器
可通過以下方式進行調整:
?設置參數(shù)Act Filt 1時間(5.29)=0.01s,以及開始自動調諧(*)
?如果失敗,設置Act Filt 2時間(5.30)=0.01s并啟動再次自動調諧(*)
?如果失敗,設置Act Filt 1時間(5.29)=0.02s并啟動再次自動調諧(*)
?如果失敗,設置Act Filt 2時間(5.30)=0.02s并啟動再次自動調諧(*)
?如果一次又一次失敗,嘗試找出正確的值
通過手動速度調節(jié)。在大多數(shù)情況下,速度調節(jié)KP(5.07)=1.000,速度調節(jié)TI(5.08)=100.0ms作為啟動條件是有用的。
只有成功調試的自調整才會更改速度控制器的參數(shù):速度調節(jié)器KP(5.07)和速度調節(jié)TI(5.08),其他參數(shù)保持不變。自整定后,必須在低速下檢查驅動器的性能。
(*)要啟動速度控制器自動調諧,設置參數(shù)控制服務(7.02)=Sp自動調諧并啟動
使用操作系統(tǒng)上的LOC和(I)按鈕驅動面板DCS400PAN或ON,并在終端。
Hints for speed controller autotuning Only successfully commissioned selftuning will change parameters of the speed controller Speed Reg KP (5.07) and Speed Reg TI (5.08), other-wise parameters remain unchanged. After selftuning the behaviour of the drive must be checked at low speed. During selftuning the motor accelerates twice up two 80% nominal speed. The application must allow this, if not, selftuning must not be carried out. In some cases selftuning will be inhibited by the application. What allows selftuning: ? motor decoupled from load ? motor + belt transmission ? motor + gear box ? motor + application with 10% load What inhibits selftuning: ? oscillating load ? full load / overload ? high inertia ( causes long reaction periods) It is not recommended to start selftuning with: ? cranes / elevators (selftuning is disregarding the lift height) n Speed Autotuning failed If autotuning fails during Commissioning Wizard: ? Reset the alarm by pressing the MENU button at the operating panel. ? Press ENTER and follow the Commissioning Wizard up to the end. ? After finishing the Wizard the speed controller can be adjusted in the following way: ? Set parameter Act Filt 1 Time (5.29) = 0.01s and start autotuning (*) ? If fails set Act Filt 2 Time (5.30) = 0.01s and start autotuning again (*) ? If fails set Act Filt 1 Time (5.29) = 0.02s and start autotuning again (*) ? If fails set Act Filt 2 Time (5.30) = 0.02s and start autotuning again (*) ? If fails again and again try to find out the right values via manually speed tuning. In most cases Speed Reg KP (5.07) = 1.000 and Speed Reg TI (5.08) = 100.0ms is helpful as a start condition. Only successfully commissioned selftuning will change parameters of the speed controller Speed Reg KP (5.07) and Speed Reg TI (5.08), other-wise parameters remain unchanged. After selftuning the behaviour of the drive must be checked at low speed. (*) To start the speed controller autotuning set parameter Contr Service (7.02)=Sp Autotun and start the drive by using LOC and (I) button at the operating panel DCS400PAN or ON and RUN command at the terminals.
