【正文】 engage the empty one. Then, renew the AUTOTUNING procedure by selecting a lower bandwidth (Bandwidth = Medium or Low). If the problem remains, renew the AUTOTUNING procedure by activating theantiresonance filter (Filter = Ant resonance). Increase progressively the parameter Speed regulator gain ratio (Max/Min) in the module Winding/unwinding diameter adaptive gain up to the maximum possible value without noises in the motor. Do not exceed the limit value calculated by to the ratio between both full and empty spool inertias reflected to the motor shaft (J max motor / J min motor). If it is not possible to enough increase the parameter Speed regulator gain ratio (Max/Min) in order to obtain the required stability, remove the full spool and reengage the empty one and renew the AUTOTUNING procedure by activating the ant resonance filter (Filter = Ant resonance). Check the adjustment stability up to the maximum speed of the full spool corresponding to the maximum line encoder speed. If it is not possible to move the line encoder, disable the function Enable winding/unwinding control in the module Winding: unwinding tension control setup and send manually the speed input mand(Manual) in the box Reference of the main BPCW window. CONTROL ADJUSTMENT Preliminary remark: It is advisable to limit the motor torque during the missioning phase in order to 29 avoid a material braking if the tension regulator loop bees instable. Engage the material in the winding/unwinding system and lock it by means of the downstream traction system. Then stretch the material and adjust manually the tension. Read the value given by the tension sensor (TM) in the module Winding/unwinding tension control setup by using the push button Tension sensor acquisition and enter this value in the parameter box Tension set point 1 with logic inputs TS1 and TS2 inhibited. Initialize the parameter Maximum speed variation at 5 % and initialize the parameter Tension input filter at 1000 Hz. Initialize the Tension set point ramp parameter at a few seconds in order to get a progressive material tension. Select the submenu Tension loop adjustment accessible via the Advanced functions menu of the BPCW software. Initialize the Tension error scaling parameter at 10 %. Initialize the parameters Integral tension gain and the Derivative tension gain at 0. Initialize the Proportional tension gain parameter at its minimum value. Disable the TDI input to enable the tension regulator and activate the ENABLE input. If the tension loop is instable (continuous material unwinding or saturated motor torque), select the Reverse error sign function. If the tension loop is oscillating, reduce the value of the Tension error scaling parameter until the loop remains stable. When the system is stable, increase the Proportional tension gain parameter up to the value where its starts oscillating。 8 附錄 14 硬件配置位置示意圖 圖 81 硬件配置位置示意圖 15 TENSION CONTROL OF WINDING/UNWINDING SYSTEMS CHAPTER 1 – GENERAL DESCRIPTION The tension control for winding/unwinding systems requires the SMTI3BD1 daughter board and the 6 EEPROM. In this configuration, the SMTBD1/i amplifier controls the speed of the motor driving the spool, in order to maintain a constant material tension independently of its line speed and of the spool diameter. The material tension is controlled by the amplifier via a 176。 如果需要,減小 Tension input filter的參數(shù)值以便對(duì)張力的測量值進(jìn)行濾波。 電機(jī)運(yùn)行時(shí)有噪聲 根據(jù)電機(jī)最大旋轉(zhuǎn)速度選擇 Encoder resolution。如果仍有問題,激活反共振濾波器更新AUTOTUNING功能。 電機(jī)停止和啟動(dòng)時(shí)有噪聲 檢查電機(jī)的固定情況。 檢查第四章的布線要求。 如果張力環(huán)振蕩,減小 Tension error scaling的參數(shù)值直到張力環(huán)穩(wěn)定。 關(guān)閉 TDI輸入以使張力調(diào)節(jié)器工作并激活 ENABLE輸入。 初始化參數(shù) Integral tension gain和 Derivative tension gain為 0。 選擇 BPCW軟件菜單 Advanced functions的子菜單 Tension loop adjustment。 張力控制調(diào)整 初始化參數(shù) Maximum speed variation為 5%和參數(shù) Tension input filter為 1000Hz。 在菜單 Advanced functions 的模塊 Winding/unwinding tension control setup 中的 Spool diameter ratio (Max/Min)參數(shù)中輸入最大和最小線軸直徑的比例值。 執(zhí)行 CONTROLLER模塊的 AUTOTUNING功能來計(jì)算調(diào)節(jié)器增益。 在 Winding/unwinding tension control setup模塊中選擇 Enable winding/unwinding control 13 功能。 在 BPCW的 Analogue input模塊的 Rated speed框中選擇 Reference voltage = 10 V,用于輸入電機(jī)的最大空載轉(zhuǎn)速。 空載調(diào)整 在 BPCW主窗口的可調(diào)模塊 ENCODER RESOLUTION中選擇 MODIFY功能。 接通電源 根據(jù) SMTBD1手冊(cè)第六章的說明打開放大器 。 核對(duì) E和 S跳線端的邏輯為高電平 核對(duì)固件內(nèi)存的版本必須是 。 6 測試 檢查配置 根據(jù) SMTBD1手冊(cè)第六章的說明核對(duì)放大器標(biāo)準(zhǔn)配置。 參數(shù) Proportional tension gain是張力調(diào)節(jié)器的比例增益。 12 圖 56 參數(shù) Tension error scaling是張力出錯(cuò)時(shí)的減少因數(shù) KS,目的是調(diào)節(jié)張力調(diào)節(jié)器的增益應(yīng)用規(guī)格。此參數(shù)的可調(diào)范圍是 010V。此參數(shù)的可調(diào)范圍是 11000??烧{(diào)范圍是 0255??烧{(diào)范圍是 04095。 調(diào)節(jié)器參數(shù) 速度調(diào)節(jié)器 PI速度調(diào)節(jié)器的結(jié)構(gòu)圖如下: 11 圖 53 PI速度調(diào)節(jié)器的結(jié)構(gòu)圖 增益參數(shù)會(huì)自動(dòng)地由 AUTOTUNING 程序計(jì)算出并且可通過 Advanced Functions 菜單中的Controller parameters。可調(diào)范圍是 10V +10V。范圍是 10V +10V。其可調(diào)范圍是由 Maximum speed參數(shù)定義的電機(jī)最大速度的 0%100%。 Maximum speed variation參數(shù)是材料張力控制 PID張力調(diào)節(jié)器給定的 速度微分的最大值。可調(diào)范圍是 010V??烧{(diào)范圍是 010V。電壓范圍是 010V??烧{(diào)的范圍是 1100。其極值根據(jù)電機(jī)的最大速度而定,如下表: 表 51 (rpm) 900 3600 14000 SOLUTION 8192 4096 1024 線軸直徑傳感器的參數(shù)規(guī)格可通過 Advanced Functions 菜單中的 Winding / Unwinding diameter sensor scaling來設(shè)置。 Reverse movement功能可使電機(jī)的旋轉(zhuǎn)方向根據(jù)材料線速度材料編碼器逆轉(zhuǎn),如下所示: 圖 52 Encoder resolution參數(shù)是一臺(tái)電機(jī)所屬的編碼器的分辨率。 Maximum speed (rpm)參數(shù)是電機(jī)的最大運(yùn)行速度(線軸直徑最小時(shí))。電機(jī)的參考速度用材料的線速度、測量的線軸直徑和測量的材料張力計(jì) 算出來。 圖 51 運(yùn)行模式 卷繞控制系統(tǒng)張力控制的運(yùn)行通過 Advanced functions菜單下的 Winding/unwinding tension control 10 parameters子菜單的 Enable winding/un winding control功能來選擇。 模擬信號(hào) TM和 DIAM必須依照傳感器和放大器之間的極性接線,并且放大器的 0V 管腳必須接至單位 0V電壓。 模擬信號(hào) TM和 DIAM需要使用屏蔽雙絞線。放大器的 0V管腳和編碼器或者主放大器的 0V地線必須連接在一起。 4 連接 連接圖 主放大器的連接 8 圖 41 主放大器連接圖 主編碼器的連接 圖 42 主編碼器
