BA-ⅡControllers (Master Unit)

Master Unit CA20-M10, M40


Master unit CA20-M10, CA-M40

* Used as the master unit for single-axis control and orthogonal (or cartesian) two-axis control.
* Easy teaching is possible by a program which is created by using the ROIbot language.
* For the supply power, multi power (AC100 V-120 V, 200 V- 240 V) is used to cope with globalized production.
* The pulse train input mode is provided as the special function of the master unit, which allows control of axis travel distance and speed by pulses supplied from an external pulse generator.
* The multitask function (No. of controlled axes: 4) is also available, which allows execution of up to four tasks in the sequential mode, two or more jobs can be executed at the same time.
