Kitamura Mycenter Zero Retrofit w/ Mesa 7I92M 7I77

Could it be possible I should be using a 7i76 instead? I've been trying to wrap my head around the axis servos and found this thread. forum.linuxcnc.org/10-advanced-configura...esa-5i25-7i76-config
It appears my x and y drive are position controlled. The wiring matches the position controlled type as illustrated by the 3rd attachment

In the last photo, "Negative command pulse" on CN1- 1&2 and " positive command pulse" on CN1- 3&4 sounds like a digital input of stepping LH or RH, similar to the more common Step/Dir inputs for many stepper drivers. It doesn't sound like the +/-10VDC analog input of velocity controlled servos.

those drives may be proprietary serial. many of the sanyos are, but i think, maybe torque control?

the model name gives some clues - the T usually means torque . C is brothers proprietary serial.

these are the modes from the slightly later PY series.
S…Speed control type. T…Torque control type. P…Position control type.
X…S-T switch type Y…P-T switch type U…P-S switch type V…Internal Speed control type

of course, the "pulse" pins on the diagram suggest, not torque control... unfortunately their naming convention isnt very consistent model to model so it may be something else entirely.

Thanks for all the help. I'm tired of trying the hard way. I'm replacing all of the electronics so I know that everything works together.

It is so nice starting from scratch and being able to bring the entire machine up to date.

I think your machine got caught in the matrix.
