Hello all, I have a hardinge t42 sp that over traveled and now I can not get the X torque limiter alarm to clear. e stop is on, you have to pull and hold down e stop reset to move axis.
I have tried doing what the manual says to no avail. I had to other processes sent to me from hardinge but i dont have all the options that they want you to push.

can anyone help me out with this one?

Is this what you tried?

1. Pull out on E-Stop pushbutton (74) and simultaneously press E-Stop Reset pushbutton
(73).
2. Select the X axis Handle MPG mode.
3. Make certain that the Handle mode is in .0001 increments (previous page, step #4).
4. Monitor Diagnostic X10 bit 3 (XTQLM) and very slowly rotate the handle in the X axis
plus direction until X10 bit 3 changes from 0 to 1. A distinct popping sound will be heard
when the torque limiter resets.
When X10 bit 3 changes from 0 to a 1, the torque limiter will be reset.

5. Set the control as follows:
A. Turn the Control OFF.
B. Turn the main disconnect switch OFF and wait 1 minute.
C. Turn main disconnect switch ON.
D. Turn Control ON.
E. Reset E-Stop by pulling out on E-Stop pushbutton (74) and simultaneously pressing
E-Stop Reset pushbutton (73).
6. Test jog the axis. Complete the torque limiter reset procedure by continuing with the
X-Axis Zero Return Setup



If that doesn't work on a T42 something is likely wrong or out adjustment with the torque limiter or prox switch. Sometimes the old torque limiters get a little "sticky" try hand wheeling the axis down to a save location and jiggle the mpg hand back and forth a bit to shake the limiter a bit then try reseting it again.

yes, except all the bits were 1. none were 0 indicating a trip

That means you have reset the physical torque limiter. Now finish the procedure from the book. Step six says to "Complete the torque limiter reset procedure by continuing with the X-Axis Zero Return Setup" The alarm will not clear until you begin the x axis zero return procedure.
