I got a problem in which our fanuc robot (a M-170 with an RJ3 controller) got its jogging "disabled". The problem started suddenly after a boot, in which the pendant works fine for everything except when I turn on the pendant. The day before it was working fine and was able to edit some points in a program.

So the symptoms are as follow:
Before turning on the TP:
    -Everything works perfectly with the pendant, I can run loaded programs. Has motion, the programs run correctly.
After turning on the TP (to jog):
    -For some reason it always sends me to the macro menu after turning the pendant (no exceptions).
    -Many keys become disabled (some numbers, some direction keys, some function keys).
    -When I try to jog (with deadman, shift and an axis pressed) it simply sends one motion warning after another with no motion (JOG-007 and JOG-010)

Do you know if it could be software related? Or a global variable which causes this kind of "glitch"? Or do you know of a place which could check the TP or a trusty reseller?

The steps I already took where:
    -Boot in cold start.
    -Check if TP motion was enabled.
    -Check if a program which disables motion was running.
    -Tried to switch the pendant of a non-working robot, but they were unfortunetaly not compatible (A05B-2301-C301 HM1 vs  A05B-2301-C371 HM2)
    -Check if the TP switch was working

SHIFT_Lock


JOG-007 comes up because the SHIFT key is not being pressed before trying to JOG and JOG-010 is because you pressed the JOG key before pressing SHIFT. Kind of redundent if you ask me haha.

But I am leaning more towards a bad TP or TP cable. Check the connections and ground strap and also try to meter the pins on the cable to see if it got pinched and is shorting out. Usually this would blow a fuse but it's worth a shot.

Before you go about replacing anything, just to be sure I would check if you have INSTALL level user rights. Because after the cold start you may be running lower level rights and if there is password protection in place there may be a HMI running on the pendant that didn't have the full menu you were used to previously. If this is the case then Login and Enable the full menu.

If this doesn't solve the issue with the keys being disabled then I would go with what SHIFT_Lock said and check the wiring.

Thanks for your help! The issue is within the TP, however since I don't have its firmware file or other options to troubleshoot further, we will buy a replacement.
