4–1 Start
The START command bit, bit 00 of word n, is set to begin execution of posi-
tioning actions (effective on signal’s rising edge). The actions are executed in
order from either the initial positioning action designated in the DM area or
that designated in the IR area. Positioning actions are executed in order until
a ”single” or ”bank end” positioning action is reached, at which time START is
again required in order to begin execution of positioning actions.
When a bank end positioning action is reached or when positioning action
#19 has been performed, the initial positioning action designated in the DM
area is performed next. The valid initial positioning action and completion
codes (i.e., single, pause, continuous, bank end, and extended) are de-
scribed later in this subsection.
4–1–1 DM Area Settings
Bits 1000 to 1999 of the DM area of the PC are used as data storage areas
for the Position Control Unit, storing data such as initial positioning action
numbers, initial speed numbers, speed data, acceleration/deceleration data,
position data, completion codes, dwell times, and output codes. (Refer to 3–4
Data Configuration and Allocation for details.)
Initial Positioning Action
Number
DM word m, bits 07-00
Set to a value between 00 and 19. This number is used at:
•
Initial START after turning on the Unit (if bit 01 of word n is 0)
•
START after bank ends
•
START after completion of positioning action #19
If bit 01 of word n is 1, the initial positioning action number designated in the
IR area is used for the initial START after turning on the Unit, allowing for a
different starting point for positioning system initialization.

Initial Speed Number
DM word m, bits 11-08
Set to a value between 0 and F (hex). An initial speed number of 0 indicates
a speed of 0. All the other speed numbers set here refer to the speeds set in
DM words m+82 through m+96.
