Doosan 2600 SY II variable spindle speed

[DC CNC]

We are trying to use the M516 A__ v__ for variable spindle speed Fanuc I series. Does anyone have the proper way to call this up?

we think this is how to call it. But it doesn't seem to work.

According to this video it looks right, don't know about the P11 though.

Perhaps an option you don't have?

Hi DC,

I came across this post today while trying to figure out the same thing on my Lynx 2100 LSYB.

I was able to look through our factory parameters list (the hard copy booklet that shipped with the machine), and found that the keep relay associated with DSSV just needed to be switched on (it was off, or 0, by default from the factory, not sure why!). The keep relay on our machine was K25.1; that is, keep relay 25, bit 1. Changed this from 0 to 1, and the M516 code works as it should now! After playing around with it a bit, I also noted that it is essential to command a G50 Sxxxx at the tool change or tool path before M516 is commanded, where Sxxxx is your maximum spindle speed for that spindle. For example, our main spindle max RPM is 4500, but I had previously had this particular tool path commanded with a G50 S3500 for a facing path, and didn't want to exceed 3500 RPM. However, this was limiting the M516 function for some reason. I added a G50 S4500 before the tool path where we command M516, and it works as it should. Hope this helps, I feel like I unlocked a secret cheat code on our machine!

Thanks we'll have to give that a try

For Daewoo Puma/FANUCi

■ M516 DYNAMIC SPINDLE SPEED VARIABLE ON • Function This is the function designed to automatically change the MAIN SPINDLE speed according to a certain cycle so as to change the machining conditions. • Command M03 Sxxx. : Spindle rotation command. M516 Axx. Vxx. Rxx. (A value : Amplitude %, V value : time, R value : pause time) • Command condition The command should be given while the spindle is rotating. The function can end by M517 or RESET button. A value should not exceed 20 %. V value should not exceed 20 seconds. R value should be smaller than the half of V value. ■ M517 DYNAMIC SPINDLE SPEED VARIABLE OFF Ends the DYNAMIC SPINDLE SPEED VARICABLE function

Firstly, this video has Korean subtitles so I can only guess roughly the content.
Second, the video doesn't exactly say what I'm trying to fix.
