Jon, IIRC correctly the pre CPLD drives did not have full step morphing. Also the new drives have a much improved recirculation sequencing. This means that heat sinking requirements for the drives are greatly reduced.
Also the advantage of the CPLD design is that it makes it harder to reverse engineer the drives, as the Chinese did with the old one some years ago Cheers, Peter On 3/05/2012 11:17 AM, Jon Elson wrote: > The G201A and some other drives from years ago used CD4000 CMOS chips and > had all this.
