the homing of the machine is done with no physical limit and limit switch hooked up
since
HOME = 0
HOME_SEQUENCE = -1
HOME_SEARCH_VEL = 0
HOME_LATCH_VEL = 0
HOME_USE_INDEX = no
HOME_IGNORE_LIMITS = yes
since
HOME = 0
HOME_SEQUENCE = -1
HOME_SEARCH_VEL = 0
HOME_LATCH_VEL = 0
HOME_USE_INDEX = no
HOME_IGNORE_LIMITS = yes

I don't see it as the same as MIN_LIMIT = -0.01 MAX_LIMIT = 1500.0 is missing from the first YMAX_VELOCITY = 5000
MAX_ACCELERATION = 250.0
MIN_LIMIT = -0.01
MAX_LIMIT = 1500.0
and are the same

There _must_ be only one [AXIS_Y] section. And it must contain the axis limits.

i saw this section of the INI file
ENCODER_SCALE = 800
OUTPUT_SCALE = 10
OUTPUT_MIN_LIMIT = -10
OUTPUT_MAX_LIMIT = 10
MIN_LIMIT = -0.01
MAX_LIMIT = 1500.0

the right think to do is to have the [AXIS_Y] in Joint 1 or Joint 2?

Joint limits and axis limits are not always the same thing.
(they have the same numbers, though, in your case)
Just delete the first [AXIS_Y] section that doesn't contain the Y axis limits.

Neither. [AXIS_Y] is the [AXIS_Y] section. It could be anywhere in the INI file, but you should only have one of them.

i have one more thing to ask
in some test i use the Touch button or the Touch off button for the z axis and then in the offset tab i write the value 50
the result of that is when i open the linuxcnc i have in the display of the z axis 50 (you can see that in the previous screen shots)
how can i change this value?(my z limits are -280 to0.1)

You need to understand the difference between machine coordinates and work coordinates. The "50" is work coordinates.
If you switch the view to "absolute" (or "machine", depending on the GUI) you will see that you are still working in a -280 to 0.1 range.

hi again
i try to configure the spindle output and the home limit inputs with no success in the hal file
# external input signals
# --- ESTOP-EXT ---
net estop-ext <= hm2_5i25.0.7i77.0.0.input-00
# --- HOME-X ---
net home-x <= hm2_5i25.0.7i77.0.0.input-01
# --- BOTH-X ---
net both-x <= hm2_5i25.0.7i77.0.0.input-02
# --- HOME-Y ---
net home-y <= hm2_5i25.0.7i77.0.0.input-03
# --- BOTH-Y ---
net both-y <= hm2_5i25.0.7i77.0.0.input-04
# --- HOME-Y1 ---
net home-y1 <= hm2_5i25.0.7i77.0.0.input-05

# --- HOME-C ---
net home-c <= hm2_5i25.0.7i77.0.0.input-09
do i have to change anything else??
