A275.09 High-speed
Counter 1
Overflow/
Underflow
Flag
This flag indicates when an overflow
or underflow has occurred in the
high-speed counter 1 PV. (Used with
the linear mode counting range only.)
Cleared when operation starts.
Cleared when the PV is changed.
OFF: Normal
ON: Overflow or underflow

A275.10 High-speed
Counter 1
Count Direc-
tion
This flag indicates whether the high-
speed counter is currently being
incremented or decremented. The
counter PV for the current cycle is
compared with the PC in last cycle to
determine the direction.
OFF: Decrementing
ON: Incrementing

A276
and
A277
All
Pulse Output
0 PV
Contain the number of pulses output
from the corresponding pulse output
port.
PV range: 80000000 to 7FFFFFFF
hex
(-2,147,483,648 to 2,147,483,647)
When pulses are being output in the
CW direction, the PV is incremented
by 1 for each pulse.
When pulses are being output in the
CCW direction, the PV is decre-
mented by 1 for each pulse.
PV after overflow: 7FFFFFFF hex
PV after underflow: 80000000 hex
A277 contains the leftmost 4 digits
and A276 contains the rightmost 4
digits of the pulse output 0 PV.
A279 contains the leftmost 4 digits
and A278 contains the rightmost 4
digits of the pulse output 1 PV.
Cleared when operation starts.
Note
If the coordinate system is
relative coordinates (unde-
fined origin), the PV will be
cleared to 0 when a pulse
output starts, i.e. when a
pulse output instruction
(SPED(885), ACC(888), or
PLS2(887)) is executed.

A280.00 Pulse Output
0 Accel/Decel
Flag
This flag will be ON when pulses are
being output from pulse output 0
according to an ACC(888) or
PLS2(887) instruction and the output
frequency is being changed in steps
(accelerating or decelerating).
Cleared when operation starts or
stops.
OFF: Constant speed
ON: Accelerating or decelerating
