Normally the inputs would be wired like this:
Field-power --> LimitT1 --> LimitT2 --> 7I76E input
Also the 7i76e spindle enable is not connected on the hal file

The best way to connect the limit switch is to provide the 7i76e constantly with 24 volts and 0 volt when the switch is triggered?

Yes , Normally closed (NC) contacts are preferred for home/limit switches
since a broken wire will cause an immediate fault

Normally you would set the spindle up in pncconf.
For example, this is what pncconf generates for open loop analog spindle control
with spindle encoder:

If you get that error it likely means:
1. You have no field or VIN power (VFIELD >+ 5V VIN >8V)
2. W8 in right hand position
3. 7I76E with damaged I/O section
