Thanks, Andrew. Those should be very helpful. I didn't realize the SVST4_4 firmware supports 3pwmgens.
Andy, I am not using a 7I39, but can work with that pinout fine. For my initial testing I'm just lowpass filtering the PWM to get analog sine waves and putting those into some lab power opamp modules. I have a three phase h-bridge module design almost finished. I'll get some photos of my linear motor prototype posted soon. -- Ralph ________________________________________ From: Andrew [[email protected]] Sent: Saturday, June 23, 2012 8:20 AM To: Enhanced Machine Controller (EMC) Subject: Re: [Emc-users] bldc hal file example? 2012/6/22 Ralph Stirling <[email protected]> > I have my prototype linear motor assembled and ready > to test tomorrow.

Note that all PID parameters taken from [AXIS_0] section (for my convenience).
