11.7.2.2 Actual value- and setpoint-based evaluation "Drive in the target"

This function extension is available from software version V5.0 onwards!

An actual value- and setpoint-based evaluation on whether the drive is in the target can be carried

out by means of the output POS_bDriveInTarget and parameterisation of C02671

, C02672, and

C02673

.

• The output POS_bDriveInTarget 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 C02671

.

• At this time, the current setpoint value has already reached the target position, i. e. the actual

position and

set position are in the target.

• In the case of positioning processes with sequence profiles, the output is only set to TRUE

after the last profile to be traversed.

• The output POS_bDriveInTarget is reset to FALSE if the current actual position value of the drive

has exited the tolerance and hysteresis window set in C02671

and C02672 again after a

positioning process has been completed.

• How the modulo evaluation is to be carried out if the actual position value enters the tolerance

and hysteresis window again can be set in C02673

:

• Modulo evaluation in all cycles (Lenze setting):

The output POS_bDriveInTarget is set to TRUE again if the current actual position value of the

drive enters the tolerance window again in an optional modulo cycle

.

• Modulo evaluation only in the modulo cycle of the target setpoint:

The output POS_bDriveInTarget is set to TRUE again if the current actual position value of the

drive enters the tolerance window again in the same modulo cycle

.

•A new FALSETRUE edge at the output POS_bDriveInTarget after a positioning process has been

completed can for instance occur when the basic function is deactivated afterwards, and if the

drive axis is skewed so that the tolerance and hysteresis window is exited and then the

tolerance range is entered again.
