PULS(886) Sets the number of pulses
to be output.

(When positioning, the
number of pulses must be
set in advance with
PULS(886).)
ACC(888) Performs pulse output con-
trol with acceleration and

Specifications
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.
The following Auxiliary Area words contain the pulse
output PVs:
Pulse output 0: A277 (rightmost 4 digits) and A276
(leftmost 4 digits)
Pulse output 1: A279 (rightmost 4 digits) and A278
(leftmost 4 digits)
The PVs are refreshed during regular I/O refreshing.
