You do not need any converter just select cl-max mode from MACH 3 in ports and pins scrreen it will give you bi-phase out instead of step and direction kindly note you can not change the pin out in...

Hi
i need pin diagram for 62BM080BXE72 BL super ac servo motor if some one has please email me. attach please find the photo of encoder and motor.

Thanks Chris

For all your information can you send me a link and photo for resolver what is the diference between techo and resolver?

Hi,

I have Sanyo Denki AC servo motors on Hitachi Seki Turning Center with spec:

Motor 220v ac with 6,000P/R encoder
Torque 10NM

I want to use mach3 control.

Any Ac drive recomendations.

Hi,

I have SANYO ac servo motor with encoder but i have emerson Ac servo drive the drive has resolver input can i find encoder to resolver converter.

Any sujestions

Regards

Ahmed

I am trying to contact Uli but no answer from his side may be his email is not working or he is on holiday. If some one knows please let me know

Ahmed Rehan

Thats good news.

yes then it is 500 lines.

You can check encoder count using mach3 encoder input first try to keep 1000 counts setting for 1 inch in mach3 and rotate motor one turn if the dro shows 1 its 1000 count or line if it shows 1.5...

Which breakout board you are using ? try to bypass the optocoupler on breakout board . if you are using laptop then check the result with desktop pc
else your left side circuit of uhu has fault...

Thanks for your reply i have done the same changes except the mosfet i used irfp264 same as in HP-UHU.

Hi Henrik,

Today i made the the single ground for 12volt uhu motor supply and encoder sheild. Thank GOD the problem for o counts was solved. But another problem in x drive started as i gave...

Hi Henrik,

Should i isolate the computer ground from UHU ground and machine ground? as again there are some Ocounts also do i need to reduce the voltage of servo motor? or increase the capacitor...

hi chris

what were the modification you used? can you post the changes

regards
Ahmed

I will test 2184 without diodes as the data sheet also show direct drive. will post the result.

also to your previous question:

My setup for motor is

steps per inch = 2500
velocity= 60 ipm...

I was seeing your HP UHU circuit in which 1r21844 is conected directly to mosfet gate through 22ohm resistor but in my pcb there are these 12volt surge protection diodes which are not preforming well...

Hi Henrik,

Thanks for the screen shots. Today i was able to run the machine wih 2000pulse original encoder, ocounts were also zero. the problem i found was breakout board opto coupler 4n25 was...

Hi Henrik,

Thanks for your quick reply . My transformer is also same as yours 90v 3phase about 4kva. I will put 30,000uf capacitors as i was not using them before and i found this jitter due to...

Today i checked with another motor fitted with 250 pulse encoder it works good upto 60ipm with analyzer function on Ocounts=0 in both directions so i think the problem is with 2000pulse encoder

I...

Hi,

i am sorry it is SN75115. will check the capacitors and will put shield cable to mosfet module will let you know the result.

Regards

Ahmed

When run at very slow speed it dose not give o count at higher speed it gives more ocount and in one direction it give more ocout than in other direction with same setting.

what is the max value...

Henrik,

Do you think i should put inductor in series with motor? also i have seen in other post about load dump should i use that?

Ahmed

1. attach please find the version of pcb but the important thing is i am using external mosfet module not the on board mosfet. may be they are picking up some noise.

2. Any check points
3. can...

Encoder are FANUC 2000pulse made by fijitsu.

If i run fast it gives more o count if run slow it give less o counts.

It is hard to find new encoder here in Pakistan. I have to import them and...

i have checked o count it is giving some time 10 sometime 100 random could it be powersupply problem? also on forward movement it gives more travel and reverse it give less travel. any sujestion.
...

Any link for microcontroller based divider.

Will check for the o count. which line driver you are using?

Ahmed

I am using 2000 pulse encoder but UHU seems to not handel these pulses so i used a divided by 4 counter to reduce the pulses to 500 using CD4520 but servo run away to one side using the counter. any...

Hi,

I need colchester 3000 parameter it has fanuc ot control. If some one has its electrical diagram i also need that.

Thanks

Ahmed Rehan

Hi i repaired one german lathe fitted with fanuc 10t control it was working fine sudenly it showed bus error and when i removed the rom/ram card and put it back there was nothing on crt. i checked...

Please see my previous posts i have attach the parameter list.
