Homing with limit switches

I installed to limit switches, one at each end of the lathe Z axis.  I have a limit switch on the extreme end of the travel, on Pin 15 on my BOB and it is configured as the Max Z Limit in StepConf.  I have another switch at the extreme - end of the travel on Pin 13 configured as Limit and Home.  Both switches have been tested ising the ptest display and they are registering when I press the switches.I ran Linuxcnc and hitt Home Axis.  The crossslide mover VERY slowly to the extremen end and the throws an error and I have to override the limits and restart the machine.What I waa expecting is for the Max Limit switch on the end to trip and then reverse the direction of the travel and touch the Home and Limit switch.So I guess I have a couple of questions:1) Do I have the switches wired up wrong?  Should the both be on the same pin wired in series and set to Home and Limit?2) How do I increase the speed of the travel to a ressonable level, it currently takes 2 or 3 minutes to travel the 600 mm of the bed.atttached are in HAL and INI files 

I think the search speed issue is resolved, thanks to Aciera for telling me how to fix that.

But I am still getting errors (in the screen shots) when I try to home the Z axis.
Any guidance will be appreciated.
I was expecting that Linuxcnc would sense the + linit and reverse direction and search for the - limit/home switch, but instead I got the error in the screenshots.  I checked Override Limits and restarted the machine, jogged to the - end of travel and got an error (see the screenshots).
 

Thank you for your response, changing the velocity fixed the speed issue

Thanks for your help. The speed issue is fixed, although I found that running stepconf resets the values of the HOME_SEARCH_VEL to really low numbers when I save and exit. But I have a work around for that.

I have the home switch for the Z axis wired up but it still throws an error when the carriage hits the home switch. I just added the entries in the HAL file that you recommended, I haven't tried yet to see if that fixes the issue.

Homing is my top priority right now. Followed by spindle encoder and learning GCode.
