GE Fanuc公司最近推出的新型32位15B系列机床控制器采用Motorola 68 ECO40作为CNC主CPU,较快的DRAM(动态随机存取存储器)和一个伺服CPU。该控制器比替代的型式几乎快一倍,是15A系列速度的三倍而体积缩小一半。除此之外,机床接口CPU以每步0.1μs的速度执行梯图程序,较以前型式快30％。 15B可进8轴控制,附加2个C轴(轮廓加工主轴),并可扩展至24轴(附加2个C轴)。分辨率为0.001μm,可以用一个任选的64位Risc(精减指令集计算机)提供更精确的轮廓控制。控制器售价一般为20 000～35 000美 GE Fanuc recently introduced the new 32-bit Series 15B machine tool controller using the Motorola 68 ECO40 as a CNC main CPU, faster DRAM (dynamic random access memory), and a servo CPU. The controller is almost twice as fast as the alternative and is three times the size of the 15A while reducing in size by half. In addition, the machine interface CPU executes the ladder program at a rate of 0.1 μs per step, 30% faster than the previous version. 15B can enter 8-axis control, add 2 C axis (contour machining spindle), and can be expanded to 24 axis (add 2 C axis). With a resolution of 0.001μm, a more accurate outline control can be provided with an optional 64-bit Risc (Reduced Instruction Set Computer). Controller price is generally 20 000 to 35 000 US
