Okay after reading everything I can find I have determined a few things that hopefully will give you some idea of how to help me.
What I discovered is that there are two dip switches marked G & 5 on the lower left side of the servo drive and when I push them down toward the board (in bypass position) I am able to put all of the limit defeating switches back in the down position and the alarms cleared.
Once I did that my emergency stop button began working and the ES contactor dropped when the ES button was released.
I am able to home the machine now, but the spindle will not run from the control.
However my spindle inverter has a remote/local switch on it and I can put the inverter in the local control position and the spindle operate properly from the inverter key pad.
It seems as though the problem is in the direction of the RTK2 borard, but the limits do go through that board and do work with the two dip switches toggled.
Help is appreciated, Thanks Gary
