WE Chan, The amplifier shown on Page 12 can be used in Speed mode on CN1 pins 21 and 20
(not STEP or PULSE ) EMC2 would command the motion by an additional card ( Mesa 5i20 and 7133 for example) that would generate analog voltages to your amplifier. The 5i20 would actually generate PWM, the 7i33 would translate/integrate the PWM into analog. Your motor would pass the encoder information back to the 7133 and then to EMC2 to close the position loop. regards TomP ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
