[r,theta machine tool kinematics]

No, that's not what I was trying to communicate. When you program the path in Cartesian coordinates (e.g. X & Y), and use cutter radius compensation, PMAC will automatically offset the Cartesian path properly by the radius and direction you specify.

 

Points on the already-offset path are then input to the inverse kinematic subroutine. The IK subroutine does NOT need to perform any offsetting, as this has already been done. It works the same way whether or not any offsets have been applied in Cartesian space.

 

Thank you Sir,

 

I also did same thing , like taking care of CCR in (x,y)

 

But it update all points in 1st and 2nd quadrant coordinate file when CCR is on.

For example....

Step 1 : x 200 y 200 // (r=282.46 , theta =45)

Step 2: x -200 y 200 // (r=282.46 , theta =135)

Step 3: x -200 y -200 // (r=282.46 , theta =225)

Step 4: x 200 y -200 // (r=282.46 , theta =315)

 

If CCR is disable then it will update all the point and execute all program .

And when we put CCR it will execute upto step 2 as soon as step 3 starts it will immediately stop the program and give coord[1].Errorstatus=5.

[r,theta machine tool kinematics]

To be clear -- to use cutter radius compensation, you must be programming in Cartesian coordinates.

 

If your mechanism is polar, you must use our kinematic subroutines to convert the offset Cartesian tool-tip trajectory to the polar actuators. This occurs at a later step in the processing.

 

Means i have to add this cutter compensation value in term of counts in kinematics subroutine as a Motor1offset or Motor2offset value.

[r,theta machine tool kinematics]

Dear Sir,

 

I also doing same type of project .

I converted Cartesian to polar points but cant enable CCR its works for 0-180deg only above 180 prog stops/prog running bit goes to zero.

 

have you added this CCR mode in your project???

Let me know how to add this functionality ???

[linear motor tuning with 1nm scale]

Dear Sir,

 

I want to tune linear motor having scale 1nm.

Details as below ...

Pole pair pitch=32mm

encoder resolution = 1 nm (Having quadrature pulse output )

 

i did following settings in encoder conversion table.....

I8000=$378000

I8001=$018000

I8002=8000

I8003=$3F8000

I8004=$010008

I8005=240

I103=$3503

I104=$3503

I183=$3506

I170=1

I171=125000

 

is it ok or anything else i have to do...........

current loop execute properly...

but while auto tuning it shows error no enough points gathered.....

 

Kindly guide me .......

[Clipper 5th axis homimg]

Thank You Sir,

 

But , JTHW port we are using and connected to Acc 34AA....

 

I used 2 step homing method and its working .......

I did first homing on user flag and second homing (index) on home flag.

 

Ok Thanks again And Happy New Year to all.

[Clipper 5th axis homimg]

Hello Everyone,

 

I have 4 axes clipper controller with op-12 ,i configure 5 axis and its working fine.

But i faced problem during homing in handwheel port only A,/A,B,/B singnals are available C,/C (index pulse) missing .

 

I have to home this axis on home switch + index pulse........

 

Is their any solution for this........

or other any way to home this axis on home switch + index pulse.....

[modbus io]

Thank you sir ,

i got solution for this but i saw it not update values every time i have to assign value to register

e.g i did set up for write 4 coils

timer =1

fc=16

count=4

update pmac.....

reg 1 m1000->x:$10780,0,16

reg 2 m1001->y:$10780,0,16

reg 3 m1002->x:$10781,0,16

reg 4 m1003->y:$10781,0,16

 

while updating value to this register every time i have to assign values to reg then save and $$$ cmd to see this values in MODBUS Slave software .......

 

any way i have to read modbus on PC and its solve means i am confident on our device sending correct values to modbus slave software.

 

once again Thank you to all.

Also checked using cmd prompt its ping successfully.

 

Let me also confirm which type of ethernet cable should i use straight/cross.

 

i attached pdf of all settings,

[modbus io]

Thank you sir,

 

i read all notes and tried to setup connection between PMAC and PC with modbus slave software for this i used standard ethernet cable .

i having UMAC controller + PC

UMAC and PC comm on Ethernet cable

According to excel sheet (PMAC modbus client master..tab)

 

i did setting accordingly

 

but modbus slave soft gives error...cannot assign requested address.... error 10049

[modbus io]

Thank you sir,

 

previously also tried fc=5 with count=0,but didnt work

i tried with both cmd

fc=5

mod ref =0

pmac ref=0

count=1.................for single coil

m6070->x:$10780,0,1 .....for coil on/off

 

 

fc=15

mod ref =0

pmac ref=0

count=16.................for multiple coil

m6070->x:$10780,0,15

 

let me try once again......

 

thank you.

[modbus io]

Thank you Sir ,

 

But i did all possible settings but i can,t proceed i am using wago 750-352 coupler+750-1504 16 DO module+ end module

modbus setting are as below

i67=$10700

Addr off=112

active socket 1

geobrick ip address 192.6.94.5

wago module ip: 192.6.94.17

fc=5

modbuf ref=0

pmac ref=0

count=16

update commd 0

update pmac

in modbus setup.

in pmac for forcing coil from pmac

i assign addr to m variable as below

m150->x:$10780,0,1

 

and from terminal window i gave value

m150=0/1

 

but coil are not activate.....

i tried checked for next 10780-10980

but coil not activate.......

 

is their another setting or i have write any program in geobrick

 

please guide me .......

[Modbus help]

Dear Sir,

 

I am using wago modbus io 16 digital outputs with geobrick.

modbus modules as below.....

Wago coupler+16 do module+end module.

 

i did all necessary setting but i don't know modbus ref# for wago do module.

if you have some thing info please share me.

 

if i have to write coils of wago module,then i have to write any program or configuration to geobrick or is their any setting related to this

[modbus io]

Thank you sir,

 

i did all setting according to modbus setup configuration....

i am using coupler + 16Do module +end module

As per the slide do will read at address I67+$95

Means my io will read on

e.g i67=$10700

then DO address will start from I67+ $95=$x:10795

[modbus io]

I want to use modbus io on geobrick can any bady tell me procedure for reading modbus digital input outputs...please
