Hello everyone, I'm hoping someone can help me out here. I'm trying to
set up a delta tau motion controller ( vme bus model in a standalone setup )
and I'm not having much luck. I have checked all the jumpers on the board
and I'm pretty sure I have them correct. I can communicate with the
controller with the pmac software, and have set the I-variables to the
factory default. The problem is I can't get any response from the DAC's
( analog output). When +/- 15v is applied to the card I get about +/- 3.8v
at the output channels for all the axis, even if the motors are disabled by
the controller. If a motion command is issued no voltage swing occurs it
just stays at 3.8v. I have the limit switches and amplifier faults disabled,
and have toyed with the DAC bias and gain--- still no change. I would
think that the DAC voltage should be zero if no motion is commanded or the
motors are disabled am I on the right track?
thanks in advance for any opinion.
