(1) Internal relays for positioning control are not latched even inside the latch
range.
In this manual, in order to indicate that internal relays for positioning
control are not latched, the expression used in this text is "M2000 to
M3839".
(2) Internal relays for positioning control are monitored from peripheral
devices as shown below.
(a) When peripheral devices are started with GSV13PE/GSV22PE,
positioning control internal relays within a latch range are indicated
by L2000 to L3839.
