Parameter LZR (bit 6 of No. 1300) selects whether each check becomes
effective after the power is turned on and manual reference position return
or automatic reference position return by G28 has been performed or
immediately after the power is turned on.
After the power is turned on, if the reference position is in the forbidden
area of each check, an alarm is generated immediately (Only in G22 mode
for stored stroke check 2).
When the tool enters and forbidden area and an alarm is generated, the tool
may only be moved in the direction from which the tool came. First move
the tool out of the forbidden area, then clear the alarm by reset. If
successfully cleared, the tool may be moved in both paths.
