Wow I looked close at that chart to and it does say
+-10v analog. That is messed up. As I'm sure it's pulse.
I can't believe they would have a typo like that.
Signal and power section does say
5 – 20 kHz Pulse Width Modulated
Digital Input Command (2.5 - 15 V). Duty Cycle
Commands The Output Current.
So probably ok to assume it is correct. Wonder if they
would respond to an email asking.
Will look into that. Maybe check in if there is a
pluggiable replacement module to match this out dated /
discontinued one. So I can avoid having to setup a
completely new control board in case one nukes out.
Course they probably last close to forever anyway

I'm pretty sure it is pulsed Input as the input
pin is marked pwm and think it said several places
on the instructions I saw it was pulse. If it is
analog they suck at labeling their modules as it
says pwm and direction labeled pins on the module.
Once I figure what pins are which on the db
connection from the machine are the encoder signals
I think the kflop would be a drop in between that
and controlling the servo amps. Now to just find
the time.

Hi Bill,
I Googled the drives and found this:
http://www.a-m-c.com/download/datasheet/10a8dd.pdf
I think it has a typo saying it has Analog
Input. But it should work with KFLOP pwm
outputs.

Gravograph new Hermes machine. They made 3

The machine it self is a standard DC servo
machine with encoders. So considering
using the existing advanced motion
controls 10A8DD amps in the control and
replacing the closed loop controls ahead
of those with a kflop.
Thet board in the unit also controls the
variable spindle and other functions so if
anyone already reverse engineered control
of that might also be helpful. Else I'll
have to figure it out.
Thanks
