Outline of Initial Setting Area This area includes the following data.
Each MC Unit uses two words as a Fixed DM Area (i.e., an initial setting area)
between DM 1000 and DM 1999.
If an Expansion DM Area is effective, the area occupies 23 words except from
DM 1000 to DM 2599. The first word of the Expansion DM Area is specified in the
initial setting area.
Note Each unit number must be unique. Do not set unit #9 and F.
A variety of data is allocated to this area to control tasks and axes for program
operation, stop, continuous operation, origin searches, jog origin return opera-
tion, or present position monitoring.
Description
For example, if bit 01 of word n+5 is set to ON, the X axis will start an origin
search.
· Data to determine whether to use the Expansion DM Area.
· Data to determine the first word in the DM or EM Area from which the Expan-
sion DM Area is allocated.
This area is referred to only once when power is supplied to the MC Unit or when
the MC Unit restarts.
