Description
Technical field
The utility model is related to fields of numeric control technique, in particular to a kind of servo-driver and servo-drive system.
Background technology
Numerically-controlled machine tool is the letter of numerically-controlled machine tool (Computer numerical control machine tools)
Claim, is a kind of automated machine tool equipped with program control system.The control system can logically handle with control coding or
Other symbolic instruction regulated procedures, and decoded, with the digital representation of code, numerical control dress is inputted by information carrier
It sets.Various control signals, the action of control lathe, shape by drawing and ruler are sent out by numerical control device through calculation process
It is very little, automatically part is processed.
Existing numerically-controlled machine tool is generally 3 axis lathes, i.e. X, Y, and Z axis can only be moved along 3 axis, but present processing system
The multiple faces being frequently necessary to workpiece on same lathe during making are processed, so needing workbench not only can be front and back
It moves left and right, it is also necessary to be rotated along X-axis or Y-axis, to realize that multi-panel is processed, when further promoting machining accuracy and reducing processing
Between.
The method of the axis servomotor of lathe extension at present mainly has following 2 kinds：
1, digital control system directly supports extension axis servomotor control
Since some digital control systems directly support extension axis servomotor, place only to need the relevant parameter being arranged on lathe, so
Some control lines in digital control system are connected on motor or motor driving machine afterwards, extension can be completed.
2, pass through digital control system PLC programming extension axis servomotors
Motor driver (control of I/O signals) is controlled by the PLC built in numerically-controlled machine tool, then again by PLC and numerical control system
Motor control is completed in system communication.
But the mode of existing numerically-controlled machine tool extension axis servomotor, have the shortcomings that following several in practice：
1, most of digital control system does not support extension axis servomotor, can not directly extend.
2, some digital control systems for supporting extended axis need in addition to buy function choosing-item again in extension, and can only make
The driver and motor being compatible with digital control system, so with high costs.
Although 3, being declined by the cost of the axis servomotor of PLC extensions, installation and debugging are complicated, and need to occupy multiple
I/O, and generally go out lathe manufacture when will not reserve it is I/O too many, and PLC extend axis servomotor can not pass through digital control system
Programming Control (for example shaft position can only use preset several positions).
4, the connection of PLC extended circuits is complicated.
5, it modifies to the PLC built in numerically-controlled machine tool, risk is big, all prohibits in most of numerically-controlled machine tool manufacturer guarantee clause
Only change PLC.
In conclusion the applicability of existing several frequently seen numerically-controlled machine tool extension axis servomotor scheme is weak, it can not be a variety of
Digital control system is installed.
