With the large number of stepper motor control to market bearing grinding machine, stepper motor control system is also an increasing number of surface, single-axis stepper motor control system is also less, but more than two-axle The stepper motor system, such as the two systems are often not synchronized, such as size, scattered and poor fault instability.
Stepper motor system problems are manifold. We groove ball bearing inner ring analysis done grinder, has tried several brands of internal stepper motor and found that the two systems are not synchronized is very serious. Sync error test from the PLC, digital control module, stepper motor drives and stepper motor to start.
Ball Screw lead 4mm, harmonic reduction ratio reducer to 1:80, step-by-step moment angle of 0.9 °.
Stepper motor positioning error has been repeated more than machine accuracy of the test 3 times. In accordance with the pulse equivalent to 0.125μm, the table repeat the positioning error in a total of 20 times has been achieved 0.003. Table 1 Description of the data is not just stepping motor error, the error of the mechanical system becomes even more evident.
Recently, Ray has taken the lead in the domestic game companies to launch a leading all-digital stepper drive products - DM series. The series contains DM422C, DM432C, DM556, DM856 four models, covering the operating voltage 18-80VDC, can drive stepper motor specifications 42,57,86. DM Series all-digital collection of the United States drives the most advanced stepper drive technology and the latest step drive Lemire research results, using 32-bit DSP processor, the realization of the nine revolutionary technology, integrated indicators have reached the level of world-class direct to step class price performance servo-driven. |
