Self-adhesive printer driver is divided into two parts: pull paper drive (servo control) and printing paper up and down movement (inverter + cam control); printing paper continues to run at a set frequency and touches upwards during upward movement of the paper The printing template completes a printing operation. After the printing is completed, a signal is output through the proximity switch to the servo controller to control the servo motor to run for a certain distance to prepare for the next printing. Electrical control principle: HMI + PLC + SERVO parameters set by the user to pass through the servo controller PLC Modbus communication via the HMI. All the functions and parameters of the printing press are set and changed through the human-machine interface a) Manual pull function NOTE: Press the ESC key on the panel to perform the manual paper pull function on this page. The other pages are invalid. b) Pull paper parameter setting page * How to operate: In this page, press the up, down, right key to move the cursor to the data to be modified, press the ENTER key to enter the data can be changed state, use the right mouse button to move the cursor To change the bit, use the up/down keys to change the value, change to the desired data, press the ENTER key twice to complete the change, and finally press the ALARM key to save the parameter. * Pull length setting: 0-99999 Unit is 0.01mm, for example 22222 stands for 222.22mm * Pull speed: set the motor speed in rpm * Implementation method: Since the unit set on the man-machine interface is mm, and the unit inside the servo controller is Pulse, the mm must be converted to Pulse. The formula is as follows: * After setting, the two parameters are transmitted to the Position and Speed ​​data area in the data set of the servo controller via the Modbus bus via the rising and falling edges of ENTER. Refer to the notes in the PLC program for the specific PLC implementation method. * Number of print counts (%MD130: Read/write): Calculate the number of prints in the count state can be modified as needed Modifying method Same as above. * Set the number of prints (%MD126): Set the number of prints to be scheduled The machine automatically stops when the print count count is greater than or equal to the set value. *Total: The total number of printed sheets contains the count when the device is in a non-printing state. * Use the ALARM button on the panel to switch whether the device is counting (%M31) * One-to-Second Printing Conversion When the type of color required for printing is greater than the maximum color that can be printed at one time, the printed object will be printed for the second time. This printing is a two-step printing, and the first printing is a one-time printing. If once printing is not good, the second printing will be even worse. * Second printing method: * Use the ALARM button on the panel to change the one- or two-step printing status (%M33%). In the second printing, the electric eye will automatically power on (%Q0.5). * In the second printing state, please perform the manual operation of the printer to trigger the servo motor to automatically search the color mark. If the motor does not find the color mark signal within 3 seconds, it will stop automatically. * Acceleration/deceleration setting page When the user's number of prints (%MD148) reaches the number of PLC presets (10000000), an internal bit (%M65) will be output, the page of the departure is displayed, the customer is asked to enter "9999" in the page, and the device is stopped When the user enters the correct data, the device automatically runs again. The user must enter the correct password to write data. Others: After the power switch is turned on, the 7-segment display code on the servo driver will be displayed as 4. After the printer inverter is started, the servo driver will be enabled (current injection motor). The 7-segment display code on the servo driver will be displayed as 6. . The servomotor will perform the corresponding action after the camshaft sensor gets a signal.
Method of realization: In this state, a manual forward signal (Terminal: 19) is given to the servo controller when the automatic output signal (%Q0.7) output by the PLC to the servo is disconnected by an internal relay (%m58).
Fine tune: unit is 1 pulse (minimum unit of motor rotation) + increase, - decrease 1 pulse is about 0.005mm
Actual: Displays the number of pulses actually input to the driver
Pulse:=16384(Resolution)*10(Gear ration)/3.1415926(âˆpai)/150(Diameter)
All conversions are implemented internally in the PLC and speeds are reported in RPM (rev/min) directly to the servo controller.

Implementation method: When the printing press completes a printing, and the system user selects the counting state, a signal is given by the proximity switch (%I0.0) and the counter in the PLC is incremented by one.
Implementation method: When the system is in the counting state, the current printing technology value (%MD130) will be compared with the setting value (%MD126). If the current printing quantity reaches a predetermined quantity, the PLC will output a signal (%Q0.3). The system stops. All functions are realized by the PLC with specific reference to the PLC program and comments.
At the time of printing, a color mark is printed on the object to be printed as a position reference for the second printing. * When the system status is switched from one-time printing to second printing, the servo motor runs the PTP command for this distance first, and the position of each color standard is calculated to determine the position of the next PTP to eliminate the accumulated error.
