n速度测量调整调试步骤
在调试过程中,是否调整步进速度-是,电机将在首次确认启动后转动
驱动-在EMF模式下按(I)12.5%的基准
速度(1.05)或模拟转速表或编码器模式基本速度的25%(1.05)。
如果此速度太高,无法进行首次应用检查不要使用此调试步骤!
现在退出调试向导并执行此操作
首先,使用操作系统通过本地控制进行检查
面板DCS400PAN。请参阅第6.1章面板
模式:驱动控制。之后,再次启动调试向导,提示速度控制器自动调整
只有成功调试的自调整才会更改速度控制器的参数:速度调节器KP(5.07)和速度调节TI(5.08),其他参数保持不变。自整定后,必须在低速下检查驱动器的性能。
在自整定过程中,电机加速两次,最多两次额定速度的80%。应用程序必须允许,如果没有,则不得进行自整定。在某种程度上应用程序将禁止自动调谐的情况。
什么允许自调整:
•电机与负载解耦
•电机+皮带传动
•电机+齿轮箱
•电机+10%负载应用
抑制自调谐的因素:
•振荡负载
•满载/过载
•高惯性(导致反应时间长)
不建议在以下情况下开始自调谐:
•起重机/电梯(自整定不考虑电梯高度)n速度自动调谐失败
如果在调试向导期间自动调整失败:
•按下以下位置的菜单按钮重置报警:操作面板。
•按ENTER键,并按照调试向导进行操作直至结束。
•完成向导后,速度控制器
可通过以下方式进行调整:
•设置参数Act Filt 1时间(5.29)=0.01s,以及开始自动调谐(*)
•如果失败,设置Act Filt 2时间(5.30)=0.01s并启动再次自动调谐(*)
•如果失败,设置Act Filt 1时间(5.29)=0.02s并启动再次自动调谐(*)
•如果失败,设置Act Filt 2时间(5.30)=0.02s并启动再次自动调谐(*)
•如果一次又一次失败,尝试找出正确的值
通过手动速度调节。在大多数情况下,速度调节KP(5.07)=1.000,速度调节TI(5.08)=100.0ms作为启动条件是有用的。
只有成功调试的自调整才会更改速度控制器的参数:速度调节器KP(5.07)和速度调节TI(5.08),其他参数保持不变。自整定后,必须在低速下检查驱动器的性能。
(*)要启动速度控制器自动调谐,设置参数控制服务(7.02)=Sp自动调谐并启动
使用操作系统上的LOC和(I)按钮驱动面板DCS400PAN或ON,并在终端。
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.
