custom synApps IOC should set motor SREV=8000 for all motors #23

Closed prjemian closed 1 year ago

prjemian commented 3 years ago

Can it go to 10000? Even 200000 (2e5), but check the upper and lower limits, HLM, LLM. This will give 5 digits of precision. That's needed to simulate crystallography and monochromators.

prjemian commented 3 years ago

The current default is 0.01 step size. Too small for most instrument axes, only OK for simple testing.

prjemian commented 3 years ago

Might be too much resolution for the monochromator code, check on that

prjemian commented 3 years ago

Instead, change the MRES value from 0.01 to 0.0001 in motorSim.substitutions

prjemian commented 3 years ago

That's easy since the customize_xxx.sh script rewrites that file anyway.

prjemian commented 3 years ago

Still, with MRES=1.0e-5, the motor stops moving positive at 0.32, although HLM=32000 (and DLM=32000, too).

The problem is in xxx/iocBoot/iocxxx/examples/motors.iocsh where LOW_LIM=-32000 is defined but there is no definition for HIGH_LIM. Confirmed that addition will fix the problem with the limit switch triggering at unexpectedly low values.

prjemian commented 3 years ago

No, the problem remains. (The test in the report above has MRES=0.01.) When test was repeated with MRES=1.0e-5, the HLS was triggered and motion stopped at RBV=0.32.

Must wait for resulution in motor module

prjemian commented 3 years ago

This issue was not affected by the fix in #24.
