All,

Thanks for the various replies.

If I look in the XPS web interface I don't see any errors reported there. Should I expect to see them there?

The stages actually move normally. And report statuses that would be expected, "Ready from Homing", "Reading from Moving", ...

Also I have two different stage types connected and both types produce this error.

The XPS configuration was generated by the XPS using that option as available in the web interface. Limits, velocities, ... appear to be set correctly. So I can't tell what the XPS is complaining about.

I once had a problem that the configured velocity (in the motor record)
was not allowed by the XPS.  It returned the same error code.  This was
a manually configured motor.   We had to play around a bit to get the
XPS configuration correct.

John:

What is your configuration in the XPS controller?
Can that have some influence?

Hi,

It could also be that the XPS axis is in the wrong 'state'. I think
it needs to be in 'ready state' (states 10 to 13) to receive move
commands.

I updated the XPS driver recently. So in the next release of the
motor support module the driver should indicate if there is a problem
(via the motor record MSTA field). So if the axis is in a state which
means you can't move it then you will be notified by the record going
into alarm state.

Cheers,
Matthew

Hi John,

If you translate that error code, -22, using ErrorStringGet in the XPS
Web terminal interface you will get:

0,Error -22 : Not allowed action

So there is something illegal about the request you are making.  Is it
possible that you are exceeding a soft limit, etc.?

Mark

All,

I am using Motor Record R6-4-4 , EPICS R3.14.9, ASYN 4-9 with a Newport
XPS controller.

When I send a new position to an actuator I get a messages in the IOC
like this:

epics>   2011/06/24 12:35:35.552 SendAndReceive unexpected response
=-22,GroupMoveAbsolute (GROUP2.POSITIONER,12.00003072008),EndOfAPI

otherwise everything seems to be working, i.e. motor responds properly.

Does someone know what this means? The XPS set-up portion of my st.cmd
script is below.

Regards and Thanks,

John Dobbins

Cornell University


The XPS set-up portion of my st.cmd script:


# cards (total controllers)
XPSSetup(1)

# card, IP, PORT, number of axes, active poll period (ms), idle poll
period (ms)
XPSConfig(0, "erpxps01", 5001, 3, 10, 500)
# asyn port, driver name, controller index, max. axes)
drvAsynMotorConfigure("XPS1", "motorXPS", 0, 3)

# card,  axis, groupName.positionerName, stepsPerUserUnit
# PR50CC rotational stage
XPSConfigAxis(0,0,"GROUP1.POSITIONER",100)
# CMA-12CCCL linear stage
XPSConfigAxis(0,1,"GROUP2.POSITIONER",20480)
# CMA-12CCCL linear stage
XPSConfigAxis(0,2,"GROUP3.POSITIONER",20480)
