_8134_set_org_offset – Set ORG signal’s range
_8134_set_org_logic – Set ORG logic
_8134_set_bounce_filter – Set a bounce filter for homing
_8134_set_org_latch – Enable/diable ORG latch function
@ Description
_8134_set_home_config:
Configure the logic of origin switch and index signal needed for
home_move() function. If you need to stop the axis after EZ signal is
active(home_mode=1 or 2), you should keep placing ORG signal in
the ON status until the axis stop. If the pulse width of ORG signal is
too short to keep it at ON status till EZ goes ON, you should select
the org_latch as enable. The latched condition is cancelled by the
next start or by disabling the org_latch. Three home return modes
are available. Refer to Chapter4.1.5 for the setting of home_mode
control.
_8134_home_move:
This function will cause the axis to perform a home return move
according to the setting of _8134_set_home_config() function. The
direction of moving is determined by the sign of velocity
parameter(svel, mvel). Since the stopping condition of this function
is determined by home_mode setting, user should take care to
select the initial moving direction. Or user should take care to handle
the condition when limit switch is touched or other conditions that is
possible causing the axis to stop. Executing stop function during
home_move() can also cause the axis to stop.
_8134_set_org_offset:
This function is used for setting the ORG length. This parameter is
active when using home mode 4~7. It will escape ORG during some
phases. Please refer to Appendix A.
_8134_set_org_logic:
This function is used for setting the ORG logic. Make sure the ORG
logic is correct before homing.
_8134_set_bounce_filter:
This function is used for extend the ORG checking time to prevent
mechanical input device’s bouncing problem. This parameter is only
useful on home mode 4~7. The meaning of the parameter is the
times of I/O checking.
_8134_set_org_latch:
This function is used for enable and disable ORG latch function.
