CIA402 out of range?

Hi,
i am using cia402 component to control ASD-B3-E drives.
I get joint X following error if I jog too far on axis to either side.
I dont know where the problem is but the position value seems like it can not get past the value 2 147 475 XXX.
Could I have reached the maximum variable value?
Is it possible to scale down resolution of the cia402 component?
I tried to set E-gear in servo drive, but cia402 component seems to default it to 1.

you have reached max of int32 of encoder variable, and it is overflow,

i use scale from init in HAL file as well, and gear ration in driver is 1 to 1
so in INI
SCALE = 3355443.2 (presumably it is correct ration of encoder bit/screw pitch)

in hal file
setp cia402.0.pos-scale [JOIN_0]SCALE

also what i find that if you use internal driver gear ration it reports back only in 1mm unit because actual position is int, and if set up gear ration of pitch / mm

you will get min resolution of 1 mm on linuxCNC screen DRO.

Thanks for reply!
but I believe I have the same setting in HAL:

I have router with working area 800x800mm

+ you have different scale in INI 200, make them same, and for this it is better to use one value from INI file, just for ease of usage 

what resolution of encoder? and screw pitch?

scale from ini should not be applied as it has no mapping in HAL file

are you sure it is not used anywhere else in linuxcnc? if it is not mapped anywhere why you have it?

in my setup with 23bit encoder and 5mm pitch, i can reach up to 1200mm in one direction, before it trips in same problem of int32 overflow

Its from the old config for MESA card I think.
But anyways.
Your calculation is right, but since home position for my machine is top rear right corner, and linuxcnc starts with 0 at position value. I would have only ~600mm of travel to the left.
So I would have to shut down machine with axes in the middle of the machine to cover 800mm range, which is not acceptable.

And what would be the solution for somebody with larger router and b3 servo?

what is your encoder resolution and pitch?

you can use
MAX_LIMIT = 400
MIN_LIMIT = -400
HOME_OFFSET = -400

btw it is better to use for home not one of the limit edgess because after pawer is off, position is deviated a bit and you can land in +0.001 or -0.001 and if limits are 400 to 0 for example, then linuxcnc shows an error that you have over travel, nothing major but just annoying message shown all the time without real danger of over travel
