Function
Contain the number of pulses output from the corre-
sponding 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 decremented by 1 for each pulse.
PV after overflow: 7FFFFFFF hex
PV after underflow: 80000000 hex
A277 contains the leftmost 4 digits and A276 con-
tains the rightmost 4 digits of the pulse output 0 PV.
A279 contains the leftmost 4 digits and A278 con-
tains the rightmost 4 digits of the pulse output 1 PV.
Cleared when operation starts.
Note If the coordinate system is relative coordi-
nates (undefined 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.
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 decelerat-
ing).
Cleared when operation starts or stops.
0: Constant speed
1: Accelerating or decelerating
This flag indicates when an overflow or underflow
has occurred in the pulse output 0 PV.
Cleared when operation starts.
0: Normal
1: Overflow or underflow
ON when the number of output pulses for pulse out-
put 0 has been set with the PULS(886) instruction.
Cleared when operation starts or stops.
0: No setting
1: Setting made
ON when the number of output pulses set with the
PULS(886) or PLS2(887) instruction has been output
through pulse output 0.
Cleared when operation starts or stops.
0: Output not completed.
1: Output completed.
ON when pulses are being output from pulse output
0.
Cleared when operation starts or stops.
0: Stopped
1: Outputting pulses.
ON when the origin has not been determined for
pulse output 0 and goes OFF when the origin has
been determined.
Turned ON when power is turned ON.
Turned ON when operation starts.
0: Origin established.
1: Origin not established.
ON when the pulse output PV matches the origin (0).
0: Not stopped at origin.
1: Stopped at origin.
ON when an error occurred while outputting pulses in
the pulse output 0 origin search function.
The Pulse Output 0 Output Stop Error code will be
written to A444.
0: No error
1: Stop error occurred.
