I set the configuration string to reflect the physical switch configuration as you said,

Now it works! Thanks!

Does you motor have a limit switch? If so is the switch open when the motor hits the limit, or closed when it hits the limit?

 

You need to set the configuration string to reflect the physical switch configuration.

 

You have set the readback to be oms:m1. That is not correct, that field is used for an external readback device like an LVDT. Leave that field blank. 

 

When you move the motor in the other direction does it also show a limit?

Hi, now I’m going to test the motor control from now on.

Before I ask a question, I would like to thank the epics tech talk for helping me this step.

I’m a beginner in epics and RTOS, but I was able to come to this step with a lot of help. Really appreciate it.

 

I booted MVME6100 with epics st.cmd, MAXv controller. Now I’m trying to control motor use CSS.

I connected epics pv with css pv. And then I try to move this motor to +, the motor doesn’t work.

 

 

vxWorks system boot

 

 

snipped..

 

 

ld 0,0, "oms.munch"

 

 

cd top

dbLoadDatabase "dbd/oms.dbd"

oms_registerRecordDeviceDriver pdbbase

 

cd startup

 

dbLoadRecords("$(MOTOR)/db/motorUtil.db", "P=oms:")

< MAXv.cmd

dbLoadTemplate("MAXv.substitutions")

MAXvSetup(1, 16,     0xF000, 200, 5, 10)

str = malloc(200);

strcpy str, "AA; LMH,H,H,H,H,H,H,H;"

strcat str, "AX LTH PSE; AY LTH PSO; AZ LTL PSO; AT LTL PSE; AU LTL PSE; AV LTL PSE; AR LTL PSE; AS LTL PSE;"

MAXvConfig(0, str, 0, 0)

free(str)

The motor is “pk545nbw” oriental motor, 5 phase stepper motor.

 

1.     I set correct pv and phase to motorx_setup at

 

2.     And then when I try to click this(>) button, it doesn’t move any more.

0.00200 is the all I can move on css and real motor is not

 

3.     Is it because of this limit at motorx_all?

If it does not move because of this limit, how can I remove

 

 

Does anyone know how to resolve this problem? Please help me or give me any suggestions.

Thanks
