    Re: VSD-E USB Cable

    Any TTL-232R with 6 pin connector (5V model recommended, 3.3V probably will work too) will work.

    Thanks for update! Yes, the scale of parameters is 0-32767 which is just a 16 bit signed integer number range. PID gains are arbitrary units so scale of the units doesn't matter much.

    Hi Dave,

    I recommend setting pin 9 (IN4) as enable/disable because pin 10 (IN3) needs to be low during power-on. Otherwise drive enters in serial communication mode and many of the I/O's then have...
