11.11.2.1 Software limit positions
The parameterisable limit positions are used by the software to limit the traversing range.
• The positive software limit position is set in C02701/1 , and the negative software limit position
is set in C02701/2 .
• If the software limit positions are active, travelling commands that would result in exiting from
the permissible travel range can no longer be executed:


Note!
Software limit positions are only evaluated and monitored if the drive knows the home
position and the software limit positions are active ( C02700 = "1").
• When the traversing range is limited ( C02528 = "1") and the software limit positions
are not active, the range is limited by the software to the internal value range that can
be maximally displayed (±2
31 increments).
• For the "Modulo" traversing range ( C02528 = "2") the software limit positions are
generally not effective.
• If the error response that can be set in C02716/2 is deactivated or is only set to
"Warning" or "Information", the software limit positions are not effective in an active
manner for the basic functions " Speed follower ", " Torque follower ", and " Position
follower "!
• After the software limit positions have been exceeded, it must be ensured before
acknowledging a pending error that the setpoint applied to the SB
LS_PositionFollower is not beyond the software limit positions.
From software version V4.0 onwards , the triggering behaviour of the software limit
position monitoring can be parameterised in C02720 .
• If you want to maintain the device behaviour known from the previous versions,
select "1: Based on set and actual value" in C02720 .
