Arguments
Parameter Parameter type Data type Description
EN Input BOOL Function block enable.
When EN = TRUE, execute current MC_Home computation.
When EN = FALSE, there is no computation.
Applies only to LD programs.
AxisIn Input AXIS_REF See also AXIS_REF data type on page 442.
Execute Input BOOL When TRUE, starts the motion at the rising edge.
Position Input REAL Absolute position is set when the reference signal is detected and configured
Home offset is reached.
The value range for this input is -0x40000000 – 0x40000000 physical pulse
after the position is converted from user position unit to PTO pulse. Set the
Position value within the Soft Limit.
An invalid input value results in an error.
Error ID = MC_FB_ERR_PARAM.
HomingMode Input SINT Enum input for Homing mode
See Homing modes on page 457.
BufferMode Input SINT Not used. The mode is always mcAborting.
ENO Output BOOL Enable out.
Applies only to LD programs.
Axis Output AXIS_REF Axis output is read-only in LD programs.
See also AXIS_REF data type on page 442.
Done Output BOOL When TRUE, the Homing operation completed successfully and the axis state
is set to StandStill.
Busy Output BOOL When TRUE, the function block is not finished.
Active Output BOOL When TRUE, indicates that the function block has control on the axis.
CommandAborted Output BOOL When TRUE, command was aborted by another command, or error stop.
Error Output BOOL When TRUE, an error was detected.
ErrorID Output UNIT Error identification.
