*1 Zone signal output:
Set the zone range in parameter No.1 and 2. The signal is always effective after home return is
completed.
*2 Position zone signal output:
This feature is associated with the specified position number. The zone range is set in the
position table. The zone range is enabled only when the position is specified but disabled if
another position is specified.
Position Zone Signal can be changed to Zone Signal in Parameter No.149.
