Y Axis not working in Plasmac screen

The Y axis in the Plasmac control screen is grayed out and does not respond. When I go to the Axis screen it works fine. This is my first time setting this machine up. Using Plasmac 2.9 with Linuxcnc 2.4. I have attached a screenshot of the Plasmac screen and the INI file also.   

If it is a gantry machine then it needs to be homed before you can manually jog the Y axis.

thank you . I will try that next
