Important notices
•
To determine the limits in the programmed mode, it is
essential to execute the cal or ncal procedure first,
because this procedure clears the position counter and the
limit registers.
•
The velocities to execute the limit switch movements has
to be chosen very carefully because:
The motors are interrupted immediately if the limit-
switches are activated, this causes a back electromotive
force (bemf) that can reset the controller
To much speed can bring the axis in collision with the
the mechanical limits.
To achieve a good repeatability of the determined limit
coordinates, especially the velocity for moving out of the
limit-switches should be chosen as small as possible.
•
The broadcast limit switch teach-in procedure blocks the
Venus-1 interpreter for all other commands except Ctrl+c.
•
For safety reasons the determined limits can not be stored
permanently.
•
Software limits can be defined additionally. See command
setnlimit .
