takisawa tc-20 21-t control soft overtravel

[CVMW]

I just purchased this lathe used and it didn't come with fanuc manuals.
First powered up yesterday and I get alarm 500 when I try and send z axes home. I have 10m and 0m controles on my vmc's When I have this problem I can push a select couple of keys when power up to clear this, Is the 21-t the same? and can anyone tell me how to get by this? (button pushing sequence or parameter etc...)
P.s. First time on cnc zone, please forgive my lack of knowledge on this forum.

Thanks! Willie
