May I use PCI-7344 to control a R/C servo motor? If it can,how can I do it?

[Seal Lee]

Now I have a R/C Servo Motor (Futaba)and I need to control it by PWM signals, and I have PCI-7344, UMI-7344 and SCB-68. How can I do with these devices to control the R/C Servo Motor?

Servo motors expect a pulse every .02 seconds. The pulse should last from 1.25 ms to 1.75 ms. 1.25 ms corresponding to 0 degrees, 1.75 ms corresponding to 180 degrees. You won't be able to achieve these types of signals with a 7344 motion control board. The 7344 can do a frequency of 40 Hz or 78 Hz (which either may or may not work depending on the servo). With a resolution of 1% on the pwm, you won't be able to get a high enough resolution to control the servo.

go to robotstore.com and they have a mssc control board that controls up to 8 servo motors and plugs into your pc s serial port for like fifty bucks. Sounds like it could work for what your talking about but i dont know what this means PCI-7344, UMI-7344 and SCB-68 hope this helps. Now can you help me with my question...I have an extremely powerful home pc and I would like to control 4 bridgeport machines with this pc. I will only be using 2dc servo motors (x,y axes) per machine. I have yet to purchase them but they will have to match todays machines speed. I built my pc ( p4 2.8ghz x2 hyper threaded, 2 180gb HDs, 5 usb ports, 5 pci slots, 2gb ddr/sdram )and it could blow away those wimpy proto trak mills (much faster) and make my bridgeports comparable to much highe
r priced machines. I want to be able to do everyhing on my pc, i can make all the cad cam software, but all i need from you is a solution to this link i need to make work. Thanks, ryan from chicago
