ORG(889)
1 Hz to 100 kHz (1 Hz units)
Set in 1 Hz units for acceleration/deceleration rates
from 1 Hz to 2 kHz (every 4 ms). The acceleration
and deceleration rates can be set independently only
with PLS2(887).
The target frequency, acceleration/deceleration rate,
and target position can be changed.

CW/CCW inputs or Pulse + direction inputs
The method is selected with an instruction operand.
The same method must be used for pulse outputs 0
and 1.
Relative coordinates: 00000000 to 7FFFFFFF hex
(Each direction accelerating or decelerating:
2,147,483,647)
Absolute coordinates: 80000000 to 7FFFFFFF hex
(−2147483648 to 2147483647)
Absolute coordinates are specified automatically
when the origin location has been determined by set-
ting the pulse output PV with INI(880) or performing
an origin search with ORG(889). Relative coordi-
nates are used when the origin location is undeter-
mined.
The pulse type can be specified with an operand in
PULS(886) or PLS2(887).
Note The absolute pulse specification can be used when
absolute coordinates are specified for the pulse out-
put PV, i.e. the origin location has been determined.
The absolute pulse specification cannot be used
when relative coordinates are specified, i.e. the origin
location is undetermined. An instruction error will
occur.
