Hello everyone, I am new to EMC but I have known of it for a long time. At work I am going to replace an old 4 axis system on a laser welding system with an Aerotech system. The good news is I get to take home the old system which will make quite a nice mini CNC system. It has Servos Systems stages (X,Y,Z) and a rotary that is not working (don't really need it). The XY stage is 24x24 allowing for a 12 inch square table (which it already has). The Z travel is only 6 inches but should be enough for PCB milling and light wood/plastic/aluminum machining. The amplifiers in the system are Advanced Motion Controls B series analog amps, they are obsolete so I cant find any data on them. The motion controller is a DOS based PC running some motion control software that is very slow (the encoder polling is limited by the slow ISA bus, something like 12 ipm). Its also programmed in a proprietary motion language so its nearly useless to me.
I want to keep the existing amplifiers because they are already neatly mounted in a 19" rack mount case with power supply. But from my research I cant seem to find any Analog driver boards save for the servo-to-go ISA card and I don't want ISA. Mesa FPGA boards look real slick and they have a 2 axis board that can drive my servos but at $300 a pop its not exactly cheap. Am I not looking hard enough or is analog control not a popular method? If analog is not an easily obtainable option, has anyone used mesa/FPGA boards with a custom built DAC board for command?
