12.7.2

Parameter setting

Setting parameters is not required for the basic function "Positioning".

• After activating the function, the profile is executed which has been transferred from the

application to the basic function via the input POS_ProfileData.

• For profiles with touch probe positioning mode (residual path positioning) touch probe is

detected implicitly.

12.7.2.1

Actual value-based evaluation "Target position reached"

An actual value-based evaluation on whether the drive has reached the target position can be

carried out by means of the output POS_bActPosInTarget and parameterisation of

C02670

.

• The output POS_bActPosInTarget is set to TRUE if the current actual position value of the drive

has reached the target position of the profile to be traversed last within the tolerance window

set in

C02670

.

• Hence, for sequence profiles the evaluation is only valid for the target position of the last

profile.

• If

C02670

is set to "0" (Lenze setting), the evaluation is setpoint-based and the signal at the

POS_bActPosInTarget output corresponds to the POS_bDone signal.

Tip!
In many cases the signal POS_bActPosInTarget only has to be evaluated if the setpoint has

also reached the target position.
Via the output POS_bDriveInTarget, it is displayed whether the setpoint position and the

actual position are in the target.
