8.4.3 Limit position monitoring
8.4.3.1 Software limit positions
The parameterisable limit positions serve to limit the traversing range by the software.
• The positive software limit position is set in C01229/1
and the negative software limit position
is set in C01229/2
.
Evaluation and monitoring of the software limit positions are only carried out if
• C01229/1
- C01229/2 > 32767
• no modulo measuring system is set (C01201/1
= 0.0000 units)
• the drive knows the home position, and the software limit positions for the respective operating
mode have been activated (see following table)!
