Joint2 limit switch error

I am using thc Toma config
But it doesn't start machine untill arc ok is provided i mean by start is machine dont get out of estop even
After that whenever i try to jog anything
It says joint2 on limit switch error...
And machine turned off

How can i solve this
I don't have physical limit switch for axis

delete your *.var file
inside the mashine folder
and also the var.bak

then in your ini set all homing to zero
per joiint

no Home_sequence inside any joint
or set it to -1

WE got a mashine wirh no limit switches that got also botherd and someone did a small bash at startup that delets the var and var.bak file so no problem thince then

Thanks for your help but it doesnt seems working it still says join 2 limit switch error
There s z limit switch in hal on parport 15 in
But i doesn't connected anything to pin 15

Can This be THe problem>????
