AC servos & mach3
« on: December 16, 2013, 02:28:21 PM »
What breakout board/motion controller need to control these servo drives from mach3 ?

If possible i want board to support
>=3 axis
>=6 home-limiting switches (optical endstops)
1 optical spindle sync endstop (lathe spindle)
option to control spindle speed with vfd (inverter)
manual operation with joystick & jog speed control
option to switch on/off cooling fluid (to switch oil solenoid electric valve)
emergency stop
points in cutting tool
pause or reset cutting operation
ability to control tool turret

The pc has parallel & usb & ethernet port and i can install 32 or 64 bit windows.

thank you

Looks like these drives can accept either Step/Dir or Analogue input so your choice of controller varied but would really need to see a proper manual to be 100% sure.

As you say it is for a lathe then that narrows down the choice a bit as you will need to get a controller that supports threading.

How does your turret work? does it require a lot of I/O, if so then maybe look at the CSMIO/IP-A (analogue +/- 10v control) from CS-Lab in Poland.

I don't have manual and if i find i would be written to chinese so it would be useless
I have this translated page witch shows pinouts of driver
http://translate.google.com/translate?sl=zh-CN&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&layout=2&eotf=1&u=http%3A%2F%2Fwww.ibuyla.com%2FProduct%2Fdetails%3Fnum_iid%3D14836946575&act=url
Also i think that this drive http://www.cncmakers.com/uploads/soft/manuals/SD200_AC_Servo_Driver_User_Manual.rar is simillar to my drive (same chinese pcb but with other outer case) 

Yes i want to connect in lathe and for turret tool changer i ask if it is possible to support this feature
iam not having any turret now but iam planning to buy one like this
http://www.aliexpress.com/item/NC-turret-LD4-0620/823135700.html in future

You say that i need a controller which supports threading ...
If iam right mach3 supports threading so why i need controller that supports threading ?
Mach3 will be my controller so i need a board to connect pc with servo drives to control them from mach3

According to the link you initially gae and also the first one above  the drive supports both  Step/Dir and Analogue +/-10v command so you should be fine with whichever type of control you buy.

That toolpost should not require a huge amount of I/O.

Mach supports threading and when using the parallel port you can do it because it is written into the parallel port driver that Mach uses. When using an external controller you are not using the parallel port and thus not using the driver. That means the motion controller has to support threading, some do and some dont.

No i don't want external encoder i want parallel port but to connect servo drives with
pc i need a breakout board right ?
What breakout board must buy with these specs to connect these servos with mach3 ?

You can use the parallel port but you will have to use electronic gearing in the drive which will severely limit the resolution and/or the velocity you can achieve.
As for a breakout board, the PMDX 122 is one I have used before and found it to be excellent.
