rd 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 The following parameters are accessible in the main window of BPCW. 24 The parameter Maximum speed (rpm) defines the maximum motor rotation speed (for the minimum spool diameter). The adjustment range is between 100 and 14 000 rpm. The function Reverse movement reverses the motor rotation direction with regard to the rotation direction of the material line speed measurement encoder, as shown below. Reverse movement Encoder rotation CW Motor rotation CW FC+ stops the motor Reverse movement Encoder rotation CW Motor rotation CCW FC stops the motor The Encoder resolution parameter defines the encoder resolution for one revolution of the slave motor. This parameter allows defining the ratio between the motor speed and the speed of the material line speed Measurement encoder. The limit value of this parameter according to the maximum motor speed (Maximum speed) is indicated in the chart below: The parameters allowing the sizing of the spool diameter sensor are accessible via the submenu Winding /Unwinding diameter sensor scaling of the menu Advanced Functions. The Spool diameter ratio (Max/Min) parameter defines the ratio between the maximum and the minimum diameters of the spool to be untwined. The adjustment range is between 1 and 100. The Diameter sensor acquisition (V) allows the reading of the voltage given by the diameter sensor. The Reading range is between 0 V and 10 V. The parameter Empty spool diameter sensor value (V) defines the voltage value provided by the diameter sensor when the spool is empty (minimum diameter). The adjustment range of this parameter is between 0 V and10 V. The parameter Full spool diameter sensor value (V) defines the voltage value provided by the diameter sensor when the spool is full (maximum diameter). The adjustment range of this parameter is between 0 V and 10 V. The parameters regarding the winding / unwinding tension control are accessible via the submenu Winding /unwinding tension control setup of the menu Advanced Functions. The parameter Maximum speed variation defines the maximum value of the differential speed input mand (BM) given by the PID tension regulator for the material tension control. This parameter also 25 defines the motor rotation speed when activating the inputs JOG+ and JOG for the manual spool unwinding. The adjustment ranges between 0 % and 100 % of the maximum motor speed defined by the parameter Maximum speed. The parameter Tension input filter defines the cutoff frequency at 3db (Five) of the first order lowpass filter acting on the tension measurement signal issued from the tension cell. The value of this parameter is chosen according to the noises and disturbances of the analogue tension cell signal. The adjustment range is between 20Hz and 1000 Hz. The parameter Tension sensor acquisition allows the reading of the voltage (TM) issued from the tension Sensor. The range is between 10 V and + 10 V. The parameter Tension set point 1 defines the tension input mand (TS) for the tension regulator, when the logic inputs TS1 and TS2 are both inhibited. The adjustment range is between 10 V and + 10 V. The parameter Tension set point 2 defines the tension input mand (TS) for the tension regulator, when the logic input TS1 is enabled and TS2 inhibited. The adjustment range is between 10 V and + 10 V. The parameter Tension set point Low defines the tension reference value (TS) for the tension regulator when the logic input TS2 is enabled. This parameter also defines the threshold corresponding to the minimum tension measurement for the detection of material breaking. The adjustment range is between 10 V and + 10 V. The parameter Tension set point ramp defines the minimum authorized response time (TL) for a variation of the tension adjustment point between 0 and the maximum value (10 V). The adjustment range is between 0 and 32seconds. 3REGULATOR PARAMETERS REGULATOR The PI speed regulator structure is shown below: The gain parameters are automatically calculated during the AUTOTUNING procedure and are accessible via the submenu Controller parameters of the menu Advanced Fu。
