Servo drive motor rotates, and platen movement is driven by actuated elements such as gear, ball guide screw nats.Mounted in machine
Position measurement element on bed workbench, after the actual displacement amount for measuring workbench, after feed back in the comparator of numerical control device
It is controlled compared with command signal, and with the difference after relatively.If both there are difference, amplify after amplifier, then
Servo drive motor is controlled to rotate, until when difference is zero, workbench just stops movement.This system is known as closed loop servo system
System, the automatic control system established based on feedback principle.So-called feedback principle, exactly according to the information of system exporting change come into
Row control, the i.e. deviation by comparison system behavior (output) between expected behavior, and eliminate deviation to obtain expected system
System performance.In feedback control system, both there is the signal through path by being input to output, also included from output terminal to input
The signal feedback network at end, both form the circuit of a closure.Therefore, feedback control system is also known as closed-loop control system.
Feedback control is the principal mode automatically controlled.Automatic control system majority is feedback control system.Often transporting in engineering
The feedback control system that output quantity and desired value are consistent is set to be known as automatic regulating system in row, and handle is used for accurately following
Or realize that the feedback control system of certain process is known as servo-drive system or servomechanism；In feedback control system, no matter for
What reason (external disturbance or internal system change), as long as controlled variable deviates setting, will produce corresponding control and make
Spend elimination deviation.Therefore, it has the ability for suppressing interference, insensitive to element characteristic change, and can improve the sound of system
Characteristic is answered, system change caused by being easily subject to external disturbance in print procedure in order to avoid printer, by the way that servo is electric
Printer, in closed-loop control system, can effectively be subject to outer by the closed-loop control system that motivation is connected with servo-driver
Portion disturbs or when system change is eliminated, and makes the article three-dimensional sense that prints stronger more precisely, reduces printing cost
Input, makes article quality higher.

Pole output high level (4.8~5.2V), if signal panels continuously rotate, loophole and shading light part will alternately turn over LED
And printing opacity or shading, photistor collector will alternately export high level and low level.When sensor axis with bent axle and
When distribution cam axle rotates, loophole and shading light part on signal panels just turn between LED and photistor, LED hairs
The light gone out will be alternately irradiated on the photistor of signal generator by signal panels printing opacity and interception, sensing
Pulse signal corresponding with crank position and camshaft location will be produced in device, which is then transferred to servo-electric
Machine 11, servomotor 11 form automatically controlling for closed circuit with servo-driver 17 by signal forward path and feedback network
System, also known as feedback control system, this is a kind of automatic control system, including power amplification and feedback, makes output variable
Value response input variable value, after numerical control device sends command pulse, when command value is sent to position comparison circuit, if at this time
Workbench does not move, that is, when not having position feed back signal, command value rotates servo drive motor, by gear, ball
The actuated elements such as screw pair drive platen movement.Position measurement element on platen, measures work
After making the actual displacement amount of platform, after feed back in the comparator of numerical control device compared with command signal, and with after relatively
Difference is controlled.If both there are difference, amplify after amplifier, then control servo drive motor to rotate, until difference
When being zero, workbench just stops movement.This system is known as closed loop servo system, is based on automatically controlling for feedback principle foundation
System.So-called feedback principle, is exactly controlled according to the information of system exporting change, that is, passes through comparison system behavior (output)
Deviation between expected behavior, and deviation is eliminated to obtain expected system performance.In feedback control system, both exist by
The signal through path of output is input to, also comprising the signal feedback network from output terminal to input terminal, both form one and close
The circuit of conjunction.Therefore, feedback control system is also known as closed-loop control system.Feedback control is the principal mode automatically controlled.From
Autocontrol system majority is feedback control system.In engineering often make output quantity in operation and desired value be consistent it is anti-
Feedback control system is known as automatic regulating system, and for accurately following or realize that the feedback control system of certain process calls
Servo-drive system or servomechanism；In feedback control system, no matter for what reason (external disturbance or internal system change),
As long as controlled variable deviates setting, corresponding control action will be produced and go to eliminate deviation.Therefore, it, which has, suppresses interference
Ability, it is insensitive to element characteristic change, and the response characteristic of system can be improved.
