bHomingStartStop

BOOL

Homing

: 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.

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

Homing

: Set home position ("on the fly" homing)

• 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 at the dnMotorRefOffset_p input of

the

LS_MotionControlKernel

SB at the instant of activation is the set

home position.

bHomingResetPos

BOOL

Homing

: Delete home position

Note: With this function, positions are not deleted but only the status signals

bHomePosAvailable and bHomePosDone 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 controller is no longer referenced.

• The process outputs bHomePosAvailable and bHomingDone are

reset to FALSE.

bEnableVelOverride

BOOL

Speed override

TRUE Activate speed override

bEnableAccOverride

BOOL

Acceleration override

TRUE Activate acceleration override

bEnableSRampOverride

BOOL

S-ramp smoothing override

Note!

If the nSRampOverride_a input on the LS MotionControlKernel remains

unconnected or if "0 %" is specified as the override value, activation of the S-ramp

override results in deactivation of the S-ramp time.

• Deactivation of the S-ramp time before the start of a profile with S-ramp time

causes linear ramp generation.

• Deactivation of the S-ramp time during a traversing process, however, is not

accepted immediately in the profile generator, but the profile generator checks

automatically when an online change of the ramp form can be carried out and

then initiates it automatically.

TRUE Activate S-ramp smoothing override

bPosExecute

BOOL

Positioning

: Start travelling

FALSETRUE Execute selected profile

bPosExecuteFinish

BOOL

Positioning

: Complete cancelled profile

FALSETRUE A positioning process previously cancelled, e.g. by bPosStop or due to

a device error, is resumed by travelling to the original target.
