Behaviour in the case of active software limit positions

If the software limit positions are active, travelling commands that would result in exiting from the

permissible travel range can no longer be executed:

[8-16] Example: Traversing range limitation by means of software limit positions

If the drive is already outside the permissible travel range and the software limit positions have

been activated, only travel commands that result in the drive moving back into the permissible

travel range can be executed:

[8-17] Example: Permissible traversing direction if software limit positions active

If the software limit positions are active and a software limit position is passed ("overtravel"):

• The error response "TroubleQuickStop" takes place in the Lenze setting, i.e. the drive is brought

to a standstill in the deceleration time set for the quick stop function and does so irrespective of

the setpoint selection. The error response can be parameterised in

C00595/3

and

C00595/4

.

• The error message "Ck03: Pos. SW limit position" or "Ck04: Neg. SW limit position" is entered in

the logbook of the drive controller.

• Depending on the parameterised fault response, the drive cannot traverse until the error has

been acknowledged.

Note!

The"travel commands" mentioned in the following description are no speed setpoint

selections. In the operating modes "

Speed follower

" and "

Position follower

", an

acknowledged software limit position error ensures that traversing into the

impermissible travel range remains possible afterwards. This is because in these two

operating modes, there is no preview whether a software limit position is approached or

not with a setpoint selection.

C01229/2

: Negative software limit position

C01229/1

: Positive software limit position

Travel command possible

Travel command not possible because target position is outside the permissible traversing range.
