RE: Motor model 3 support for OMS MAXv-8000?

[Mark Rivers <rivers@cars.uchicago.edu>]

Hi Nia,

The current EPICS driver version is model 1, not model 2.  

Jens Eden told me in Nov. 2010 that he had a model 3 driver for the MAX family working. 

This is from his message:

#########################################
Yes, I have a (beta) asyn driver version for the MAX family (MAXv and MAXnet so far), 
which I recently sent to Austen and Ron. I didn't announce it on tech-talk, since I didn't 
had a chance to do some testing yet, but if anyone is interested, tell me and I will send you 
what I have. 

Using Mark Rivers ' asynMotorDriver base C++ class is very straight forward and has 
several advantages. 
- os-independent (we use it with RTEMS) 
- easy to have derived classes for the other MAX-family members (they all use the same command set) 
  (writing a MAXp Linux driver using Michael's devLib2 is on my list) 
- the asynOctet layer which Dirk requested comes for free 
   (use a stringout or waveform to send ASCII commands to the Controller) 

With this driver version you may use the auxiliary encoders or use encoders independent from their 
motor axis (which is actually the reason why I wrote this, because we want to use 2 encoders for 
a single axis). 
If this functionality is too specific, I could possibly remove it and put it into a ptb-specific derived class. 
I didn't care for OMS58 yet.

If Jens is willing I could take this driver and add the new coordinated motion API to it, and put into the standard EPICS motor distribution.  Tim Mooney has already done EPICS support for coordinated motion, but it is an SNL program (like the old XPS trajectory scanning), not using the Model 3 API.  So I would just port his code to the model 3 driver.

I was actually talking to Pro-Dex about this today, because they have developed a product that is a 10-axis MAXNet controller that plugs into the left-hand slot of an ACS Step-Pak.  This allows Step-Pak systems to be VME-independent, and with a new driver they could also do coordinated motion.  With the new Step-Paks they can also drive servo motors.

Hi,

Has anyone written a model 3 based motor driver for the OMS MAXv VME-based board?
We just ordered a MAXv-8000 Motion Controller VME board.

Is the current driver in the motor-R6-7 model 2?

Thanks in advance,

Nia
