Basic drive functions (MCK)
Homing
8.6.3 Carrying out 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:

Information/possible settings
bHomingStartStop
BOOL
Start/stop homing
• Only possible in the "referencing" operating mode.
TRUE If one of referencing modes "0" ... "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 the 100_ Set_Ref_directly" referencing mode has been selected
in C01221
, the home position can be set manually via the
bHomeStartStop input with the drive at a standstill. The current
actual position is set as the home position (C01227/2
)
If referencing mode "100: SetRef" is selected:
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.
TRUEÌFALSE 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 (referencing "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.
FALSEÊTRUE The position at the dnMotorRefOffset_p input of
the LS_MotionControlKernel
SB at the instant of activation is the set
home position.
• In addition, a desired reference position value becomes the new
"home position" after read in at dnPosProfilePosition.
bHomingResetPos
BOOL
Delete home position
FALSEÊTRUE The internal status "reference known" is reset.
• The controller is no longer referenced.
•The bHomePosAvailable process output is reset to FALSE.
