11.11.2.2 Triggering behaviour of software limit position monitoring
This function extension is available from software version V4.0!
C02720 can be used to select the triggering behaviour of the software limit position monitoring of
non-positon-controlled basic functions:
Selection "0: Based on set value"
From software version V4.0 onwards, this is the Lenze setting:
• If the basic functions " Speed follower " and " Torque follower " are used, the monitoring responds
if the drive is outside the software limit positions and a command to travel in the "forbidden"
direction is given (depending on the speed setpoint of the application).
• For all other non-position-controlled basic functions, the monitoring does not respond if a
software limit position is exceeded.
Selection "1: Based on set and actual value"
This selection corresponds to the behaviour known from the previous versions (software versions <
V4.0):
• For all non-position-controlled basic functions, the monitoring responds if the actual position
exceeds a software limit position.
• The monitoring also responds in the function states "Controller not ready" and "Error". This
may cause the monitoring to trigger permanently if the drive traverses to a software limit
position and controller inhibit is set subsequently because the actual position slightly
changes around the software limit position.
• If the basic functions " Speed follower " and " Torque follower " are used, the monitoring also
responds if the drive is outside the software limit positions and a command to travel in the
"forbidden" direction is given (depending on the speed setpoint of the application).

Note!
If the position-controlled basic functions " Manual jog ", " Positioning " and " Position
follower " are used, the monitoring responds independently of the triggering behaviour
parameterised in C02720 if one of the following cases occurs:
• The setpoint position exceeds a software limit position.
• A travel command is given which would cause the drive to leave the permissible travel
range.
• The drive is outside the software limit positions and a command to travel in the
"forbidden" direction is given.
If the software limit position monitoring is triggered, the error response parameterised
in C02716/2 is carried out.
