Linear motor drive technology as a new type of feed transmission developed in recent years, its advantages have been paid attention to in the global machine tool industry, and in Europe and other industrial developed regions set off a linear motor tide.
Linear motor can directly produce continuous single direction or back and forth linear mechanical motion, without the need for intermediate mechanical transmission conversion device, linear motor drive technology has gradually matured since its birth and development, while linear motor as a new drive technology, With the unique advantages of high precision, less wear, fast response, low noise, high operating efficiency and small size, linear motor has become the ideal transmission mode for all kinds of ultra-high speed and precision machine tools. It is widely used in laser cutting, engraving, marking, boring line, precision CNC machine tools, precision testing equipment, industrial automation, logistics transportation system and other fields.
Linear motor drive features
In the machine tool feed system, the biggest difference between the linear motor direct drive and the original rotary motor drive is to cancel all the mechanical intermediate transmission links from the motor to the workbench (drag plate), and shorten the length of the machine tool feed transmission chain to zero. This mode of transmission is called zero transmission. It is precisely because of this zero transmission mode that the original rotary motor drive mode cannot achieve performance indicators and certain advantages.
Vector linear motor special driver
As the technology leader in the field of motion control in China, Vector has not only customized various special servo drives for various industries. With a keen sense of industrial technology wind direction combined with 18 years of motion control industry experience and innovative technology research and development, the development of VC800 high-performance linear motor servo driver, integrated with the latest servo control technology, can achieve high precision control of linear motor.
The Vector VC800 linear motor driver has the following features:
Compatible with standard incremental ABZ encoders, optional HALLU HALLV HALLW.
The incremental ABZ encoder directly uses the photoelectric conversion principle to output three sets of square wave pulses A, B and Z phases. The phase difference between group A and group B is 90. Thus, the rotation direction can be easily judged, and the Z phase is one pulse per revolution for reference point positioning. The principle is simple, the average mechanical life can be more than tens of thousands of hours, strong anti-interference ability, high reliability.
It can be configured as automatic phase search on power-on. The actuator phase can also be obtained accurately under the condition of load disturbance and unidirectional rotation.
The matching motor is simple, with automatic identification of stator winding parameters, automatic identification of actuator mass, magnetic pole distance estimation, automatic setting of current loop bandwidth, and VECObserver software to quickly match linear motors.
Support dynamic braking function, in the case of abnormal conditions can make the motor fast braking, prevent the speed.
The maximum position instruction input is 4MHz, and the AB pulse can reach 16MHz after 4x conversion.
Support position correction function. After correction, the magnetic encoder can achieve a maximum positioning accuracy of ±1μm.
Respond quickly. Current loop control cycle is the fastest 80KHz, speed loop control cycle is the fastest 40KHz.
The supporting VECObserver software can control the curve operation parameters visually, and has the function of self-learning encoder parameters and gain adjustment, making the linear motor control debugging more simple and clear! And has the following functions:
Real-time monitoring of the operating parameters of any curve, read all parameters of the driver.
Save and load running curve data, analyze running curve data, execute macro command function.
inertial self-learning and gain self-adjustment function, can update the driver parameters and offline parameter editing.
