8.3 Software limit

Specify the upper and lower limits of the command position and current position. If a command position
exceeding the limit position is specified, the command position is clamped at the limit position. Specify a
relative position from the machine home point (position address = 0) as the limit position.
This function is enabled when the home position is not erased in the profile position mode (pp). While the
clamp processing is being performed with the command position exceeding the limit value, [AL. 98 Software
limit warning] occurs and not cleared. When the position command of the direction opposite to reached
Software position limit is given, the operation can be restarted.
