SYNTAX xx OR nn
PARAMETERS
Description xx [ int ] - axis number
nn [ int ] - home mode
Range xx - 0 to MAX AXES
nn - 0 to 6 where:
0 = Find +0 Position Count
1 = Find Home and Index Signals
2 = Find Home Signal
3 = Find Positive Limit Signal
4 = Find Negative Limit Signal
5 = Find Positive Limit and Index Signals
6 = Find Negative Limit and Index Signals
Units xx - none
nn - none
Defaults xx missing: error 37, AXIS NUMBER MISSING
out of range: error 9, AXIS NUMBER OUT OF RANGE
nn missing: error 38, COMMAND PARAMETER MISSING
out of range: error xx2, PARAMETER OUT OF RANGE
DESCRIPTION
This command executes a Home search routine on the axis specified by xx . If xx
= 0 , a home search routine is initiated sequentially on all installed axes. If nn is
missing, the axes will search for home using the mode specified using OM
command. If nn = 0 , the axes will search for zero position count. If nn = 1 , the
axis will search for combined Home and Index signal transitions. If nn = 2 , the
axes will search for Home signal transition only. If nn = 3 , the axes will search
for positive limit signal transition. If nn = 4 , the axes will search for negative
limit signal transition. If nn = 5 , the axes will search for positive limit and index
signal transition. If nn = 6 , the axes will search for negative limit and index
signal transition.
At the end of a home search routine, the position of axes is reset to the value
specified using
SH command.
The home search motion status can be monitored with the Motion Done (
MD )
status command. If a fault condition such as E-stop occurs while home search is
in progress or if this command is issued to an axis before enabling it, the
controller returns error xx20, “HOMING ABORTED”.
For a detailed description of the home search routine see the
Home - The Axis
Origin chapter in the Motion Control Tutorial section
