External Axis Endless

Quote from Emre64

Hello,

We have an external axis endless. It can turn according to the value that give to MTE in MOVJ instruction. I use MRESET to reset the number of turn.

I have a problem, I need the axis turn more than 32767, in the default the MTE can set only 32767. for use more than this, i use MRESET to reset the axis turn and use MOVJ for turn again but there are a problem after reset. Axis stop and start again, this is bad for my work. How can solve this problem?

My Program is below:

NOP

MOVJ VJ=10

MOVJ VJ=10 MTE= 32767

MRESET

MOVJ VJ=10 MTE=32767

END

What is the purpose of turning so many degrees? Welding? Milling?

two options for solving your problem come to my mind.

1 ) You can increase MTE= 32767 by 2 times. By creating a start point of rotation MTE= -32767 and end point MTE= +32767

2) or paid function from the manufacturer by manipulating the secret parameter FD ( Infinite rotation (Ext axis, T axis) )

I modified this from here: SYSTEM/SETUP/CONTROL GROUP/S (your station)/MECHA SPEC. and here I added 200 degrees in - and 200 in +. I hope this helps you.

Thank you for your options,

Can you give me example for option 1 that you said?

About option 2, are you sure there are function parameter for infinite rotation? Because i didn't listen about it.

Yes it exists, but involves some parameter that need the Yaskawa assistance.

Basically the MRESET is done automatically.

But if I remember remain a limit: you can go to a max value of 999999999 after that it's possible that could rise an alarm like 1656(AXIS ENDELESS INFO NOT GENERATED) or the controller will stop briefly to do a real MRESET.

you have to restart motosim before seeing the change.

you can see the alarm code here.

here is the manual with errors and alarms.

did you follow exactly the steps I said above and it still gives you an error?
