    Thank you both.
    I am reading the Parker manual and it says ...\for Fast rotation requires pin 20 of 32 Pin input socket of SD2 drive to be connected to 0volts.
    So I am now measuring the keyboard lines which leave the arrow button for manual jog, as the drive connecting socket not accessible, and is reading 4.8vdc.
    When pressing the arrow button the test point voltage comes down to 0.650VClick image for larger version.  Name: P4070719.jpg  Views: 682  Size: 281.4 KB  ID: 8763Click image for larger version.  Name: P4070720.jpg  Views: 673  Size: 243.5 KB  ID: 8764
    And when I keep this button pressed the screen shows the axis coordinates changing.
    I must be totally blind I can't see what is going on. I must be real close solving this. Please note that I used a jumper wire to bridge the limit switch computer input to save some time testing limit switches. IF I do not do this the motors de-energize. Should i have done this or not?
