Aerotech Automation1 motor questions

[John Dobbins via Tech-talk <tech-talk at aps.anl.gov>]

All,

We have a new device which includes a single axis Aerotech Automation1 motor.

I have downloaded and built  

https://github.com/epics-motor/motorAutomation1

(Alma 9,  base-7.0.6, motor - current master, Automation1 - master from October )

The IOC starts up but as there is little documentation I don't know what to expect.

Ultimately, we will be controlling this motor from SPEC (from Certified Scientific Software).  We will need to

Enable/Disable Motor

Brake On/Off

Home

Put new positions

When the IOC starts up I find it reports a position. I can command a move.   Zero position seems to agree with the Automation1 software reported zero position but when I command a move the change in raw isn't what I expect.  I should mention - I am told this set-up combines two encodes to achieve higher resolution. I need to find out more about this.

Note in the motor record:  MRES and ERES both = 0.   Changing them seemed to have no effect.

RMP always equals REP and change reasonable except for the scale factor.

I see that there exists the record:

record(waveform, "$(P)ExecuteCommand")

{

    field(DESC, "Execute an AeroScript command")

    field(DTYP, "asynOctetWrite")

    field(FTVL, "CHAR")

    field(NELM, "256")

    field(INP,  "@asyn($(PORT),0,$(TIMEOUT=4))AUTOMATION1_C_EXECUTE_COMMAND")

}

Can I, for example  send the Aeroscript command "DriveBrakeOff(1)"  as a string to that record?

Any help appreciated. 

Thanks,
