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。 檢查第四章的布線要求。 在 Winding/unwinding tension control setup模塊中選擇 Enable winding/unwinding control 13 功能。此參數(shù)的可調(diào)范圍是 010V。 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。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。材料張力是由張力傳感器所提供的 10伏模擬信號(hào)通過放大器來控制。電纜兩端都必須有 360度的盾狀連接方式的金屬連接器。 Empty spool diameter sensor value (V)參數(shù)是最小線軸直徑時(shí)的電壓值。 Integral 1 speed gain 是調(diào)節(jié)器速度出錯(cuò)時(shí)的積分增益。 主 /從開始和調(diào)整 按照 SMTBD1手冊(cè)第六章的說明用 BPCW軟件啟動(dòng)和調(diào)整放大器。 初始化參數(shù) Proportional tension gain為最小值。 10 V analogue signal (TM) provided by a tension sensor. The spool diameter measurement (DIAM) is also received by the amplifier as an analogue voltage between 0 V and 10 V. These signals are entered on the amplifier mand connector X4. The material line speed is measured by an encoder which differential signals A, /A and B, /B in quartered are received on the amplifier mand connector X2. The system structure is described below.

CHAPTER 4CONNECTIONS 1CONNECTION DIAGRAM WITH THE MASTER AMPLIFIER WITH THE MASTER ENCODER 22 2MANDATORY WIRING It is mandatory to use a shielded cable for the encoder signals A and B. Cable ends should have a 360 shield connection by means of the metallic X2 connector (refer to Chapter 8, section 6 of the SMTBD1 standard manual). The amplifier 0 V (X2, pins 10/11) and the encoder or master amplifier 0 V (GND) must be connected together. The crossing of the A and B, A and A/ or B and B/ signals on the encoder input changes the motor rotation direction with regard to the rotation direction of the encoder or of the master motor. It is necessary to use a twisted and shielded cable for the analogue signals TM and DIAM. Both cable ends must have a 360 shield connection by means of the metal connectors. The analogue signals TM and DIAM must be wired according to the polarities between the sensor cells and the amplifier (TM+ and DIAM on diff. high of the cells), and the amplifier 0 V MUST be connected to the cells 0 V by means of a cable (pins 15 and 16 must be connected together on the X4 connector at the amplifier end). CHAPTER 5ADJUSTABLE PARAMETERS The specific parameters used for the tension control of winding/unwinding systems are accessible via the Winding/unwinding tension control setup and Winding/unwinding diameter sensor scaling submenus of The Advanced functions menu, in the BPCW software version and greater. 23 1OPERATION MODE The operation in winding/unwinding tension control is selected by the Enable winding/unwinding control function in the Winding/unwinding tension control parameters submenu of the advanced functions menu. This mode corresponds to speed control of the motor that drives the spool, in order to maintain a constant Material tension independently from its line speed and from the spool diameter. The motor speed reference is Then calculated according to the material line speed, the spool diameter measurement and the material tension Measurement. 2APPLICATION PARAMETERS T
