8.6.3 Execute homing
Control is exercised by means of bits 8 ... 10 in the MCK control word:
If the Motion Control Kernel is downstream from the MCKInterface in the circuit, the
L_MckCtrlInterface
FB provides the following process inputs for controlling the operating mode:
Homing MCK control word
Bit 10 Bit 9 Bit 8

Set home position 0 1 X
Delete home position 1 0 X

Designator
Data type
Information/possible settings
bHomingStartStop
BOOL
Start/stop homing
• Only possible in the "referencing" operating mode.
TRUE If one of homing modes "4" ... "15" in C01221
is selected:
Start reference search
• The current status of the reference search is indicated via the
status outputs bHomingDone and bHomePosAvailable.
If homing mode "100: SetRef" is selected in C01221
:
Setting the home position manually
• The home position is set manually with the drive at a standstill.
The current actual position now corresponds to the reference
position set in C01227/2
in the machine measuring system.
TRUEFALSE Stop homing.
•If the bHomingStartStop input is reset to FALSE during active
referencing, homing is cancelled and the drive is brought to a
standstill.
bHomingSetPos
BOOL
Set home position (Homing on the fly)
• With referencing "on the fly", the home position of a machine can be set during
ongoing movement. Jerking and compensating movements do not occur.
FALSETRUE The position applied at the dnMotorRefOffset_p input of the
SB LS_MotionControlKernel
at the time of activation is set as home
position if C01246/2
= "0: No TP" is set.
bHomingResetPos
BOOL
Delete home position
Note: With this function, positions are not deleted but only the status signals
bHomePosAvailable and bHomingDone are reset. Setpoints and actual positions
remain untouched until a renewed reference setting or homing.
FALSETRUE The internal status "reference known" is reset.
• The inverter is no longer referenced.
• The process outputs bHomePosAvailable and bHomingDone are
reset to FALSE.
