MAKE SURE IF YOU ARE GOING MACHINE WITH ANOTHER TOOL NOT TO USE G28H0,A0 OR G30H0,A0. YOU HAVE TO USE S----M19 TO POSITION PART.
AS LONG AS THE TWO PART ARE CHUCKED TOGETHER YOU HAVE TO USE M19 TO ROTATE, IT WILL OVER LOAD SPINDLE AND OR BREAK OR BEND PART!!!

This is odd I didn't think the C2 axis went into servo driven mode unless commanded.

Generally you would just use it in spindle mode with no power to the motor

You can use torque function to move the B-Axis on to the shaft and clamp the sub chuck.

M35, Rev. tool stop, Main spindle = C1, Sub = Spindle
M135, Rev. tool stop, Sub spindle = C2, Main = Spindle

I suggest you look in the blue book in your electrical cabinet and find keep relay 10 bit 3. if you make bit 3 a 1, this should allow the "inactive" spindle to "freewheel" while the "active" spindle does all the driving.

After confirming that K10.3 is the correct keep relay, turn on your parameter write enable from the offset/settings page. You have to be in MDI to make these changes, so keep this in mind. Make the PWE a 1 and press input. You will get an alarm in regards to the Parameter write being enabled. This can be cleared by holding the Cancel button (CAN) and then pressing Reset.


Press the "System" hard key, then press soft keys, PMC, PMCPRM, KEEPRL, these are the keep relays. Use your arrow on your keypad to cursor to the fourth digit from the right and make it a 1 (1 then Input). Turn your PWE back to a 0, and you should be ready to roll.

THE MAIN IS A FULL -C,,, WHILE THE SUB IS ONLY AN INDEXING,,,YOU MUST DIS-ABLE THE SUB AND USE THE MAIN AS A DRIVER,,,, IN EFFECT THE SUB WILL FREE WHEEL AND BE DRIVEN BY THE MAIN

Bad Dog,

Do you have a 2000SY with "indexing" sub-spindle? Every one I've ever seen has a full C on both main and sub.

Here's a snippet from the proposal.
