I am doing something similar. My pwm amp is only an h-bridge driven directly from emc. Then the encoder feeds back. emc2>printerport>h-bridge>motor>encoder>printerport> ^

[Emc-users] pwm amplifier

hello I am trying to build a h-bridge pwm driver for brush dc motor at 10 amp, 80vdc. the mesa card provide a pwm output and direction output. do I need a torque/current loop on my board using opamps, or just switching motor voltage via h-bridge pwm is enough for emc servo loop. I have a 500 c

Re: [Emc-users] Which cad software?
