HOM – Home Axis
or
Axis 1 to 4
This command produces an absolute measurement reference. What
occurs basically corresponds to homing in Manual Mode. To accomplish
this, Parameters Ax23 through Ax25 must be programmed accordingly.
This command is not needed when the position is detected using multi-
turn encoders, since they already generate an absolute measurement
reference.
Otherwise, the error message ‘Illegal command’ is generated.
During homing, make sure that no command is processed which
executes a drive motion.
A query within the program to determine whether homing has been
successfully completed is accomplished by polling the ‘Homed’ output in
Parameter Ax24.
Note: In general, completion of the homing routine following each
'HOM' command should be verified using an 'AKN' command.
Example:
Input in Parameter Ax24 = M2.02.0 +100 0
0011 HOM 1 - Home Axis 1
0012 AKN M2.02.0 1 - Wait until homing is completed
0013 POA 1 +000010.000 999 - Positioning, Absolute
A detailed description of the homing function is provided in the chapter
entitled 'Homing.'
The program proceeds to the next instruction following the time period of
one cycle.
