Instructions Used for Pulse Outputs
Use the following 8 instructions to control the pulse outputs.
The following table shows the kinds of pulse outputs controlled by each
instruction.
Pulse output PV's storage
location The following Auxiliary Area words contain the pulse
output PVs:
Pulse output 0: A277 (leftmost 4 digits) and A276
(rightmost 4 digits)
Pulse output 1: A279 (leftmost 4 digits) and A278
(rightmost 4 digits)
The PVs are refreshed during regular I/O refreshing.

PULS(886)
SET PULSES
Sets the number of pulses
to be output. Used --- --- --- --- ---
SPED(885)
SPEED OUTPUT
Performs pulse output con-
trol without acceleration or
deceleration.
(When positioning, the
number of pulses must be
set in advance with
PULS(886).)

ACC(888)
ACCELERATION
CONTROL
Performs pulse output con-
trol with acceleration and
deceleration.
(When positioning, the
number of pulses must be
set in advance with
PULS(886).)
--- Used --- --- Used ---
PLS2(887)
PULSE OUTPUT
Performs pulse output con-
trol with independent
acceleration and decelera-
tion rates.
(Also sets the number of
pulses.)
