Operation Theorem
4.1.6 Home Return Mode
In this mode, you can let the PCI-8132 output pulses until the conditions to
complete the home return is satisfied after writing the
_8132_home_move() command. Finish of home return can be checked
by _8132_motion_done() function. Or you can check finish of home
return accompanied with the interrupt function by setting bit 5 of int_factor
to 1 in _8132_ set_int_factor() function.
Moving direction of motors in this mode is determined by the sign of
velocity parameter in
_8132_home_move() function. A _8132_v_stop()
command during returning home can stop OUT and DIR from outputting
pulses.
Before writing _8132_home_move() command, configuration must be set
by _8132_set_home_config() function. . See also Section 4.3.3 for
further description. There are total three home return modes can be
selected by setting home_mode parameter in
_8132_set_home_config()
function. The meaning of Home_mode will be described as the following:
1 . Home_mode=0: ORG only, no index signal. The ORG signal
immediately stops OUT and DIR pins from outputting pulses to
complete the origin return.
