In the same screen where you turn the drives on, one of your choices is TOOLCHANGER.
Under that menu you can LOAD or HOME the tool changer and another key says PASSWORD.
Press that key. The password is PASSWORD in capital letters.
Under this menu press 1 which says START setup.
The head goes to the tool change position and the spindle orients.
here you have a menu that allows you to jog the spindle using the jog knob and save the orient. It also allows you to jog the head up and down and save the tool change height.
You acn also use the jog + and - keys to bump the tool changer toward and away from the spindle to see how the fingers go onto the tool and if your orient is close.
When you save, the value actually goes into the parameter file (bmdcprms.sys).
The Parvex motor is a lot stronger and bigger than the SEM. If you look at your Z axis, you may see the label for it. It was an factory recall/upgrade that we were required to do along with a redesigned wire feed to the saddle.
I hope you got a Heidenhain encoder for the spindle. It will last a lot longer than the cheap replacement I got from Hardinge the last time I ordered one. It did not even work. Also I hope you have the correct paramters for it. There were 2 different resolutions that are in current use with these machines. If you command a spindle speed and it is wrong, then you know you need to change the parameters. Or if your spindle times out (not up to speed in time). The control expects the spindle speed to be within 20% of command or it will not do a feed rate of an axis.
I also check spindle balance (S0M03). If the spindle drifts at 2 RPM or more, it will bomb out in the middle of a tool change. Drift is adjusted at the Yaskawa spindle drive. I also check spindle speed. If it is off a little bit, I can get it to match command by adjusting parameter 71 in the bmdcprms. But this usually upsets the balance which will need adjustment again.
