2.16.1 Limit switch integration
2.16.2 Software limit positions
By the use of software limit positions the user can limit the absolute traversing range of the drive
in individual operation in a defined manner. In this way the drive can be used reliably for each
individual axis. The software limit positions are programmable positions at the outer ends of an
absolute traversing range and are normally placed at a short distance in front of the hardware
limit switches.
Activated software limit positions ensure that the drive does not move past the software limit
positions under any circumstances, even if the drive is set to positions beyond the software limit
positions by the positioning control (e.g. continuous signal on manual inching, positioning to an
invalid target position, …). In these cases early braking and shutdown of the drive is initiated by
the respective software limit position.
The software limit positions are active if
• the home position for the measuring system is known (accordingly the software limit
positions are inactive during homing) and
• the positive software limit position (C3223/000) is set greater than the negative software limit
position (C3224/000).
