Name Description Read/Write Updated
Pulse Output PV Contain the number of pulses output from the correspond-
ing 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
Note If the coordinate system uses relative coordinates
(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.
Read-only • Cleared when power is turned
ON.
• Cleared when operation starts.
• Updated each cycle during over-
see process.
• Updated when the PV is
changed by the INI(880) instruc-
tion.
Pulse Output
Accel/Decel Flag This flag will be ON when pulses are being output accord-
ing to an ACC(888) or PLS2(887) instruction and the output
frequency is being changed in steps (accelerating or decel-
erating).
OFF: Constant speed
ON: Accelerating or decelerating Read-only • Cleared when power is turned
ON.
• Cleared when operation starts or
stops.
• Updated each cycle during over-
see process.
Pulse Output Over-
flow/Underflow Flag This flag indicates when an overflow or underflow has
occurred in the pulse output PV.
OFF: Normal
ON: Overflow or underflow Read-only • Cleared when power is turned
ON.
• Cleared when operation starts.
• Cleared when the PV is changed
by the INI(880) instruction.
• Updated when an overflow or
underflow occurs.
Pulse Output, Output
Amount Set Flag ON when the number of output pulses has been set with
the PULS(886) instruction.
OFF: No setting
ON: Setting made Read-only • Cleared when power is turned
ON.
• Cleared when operation starts or
stops.
• Updated when the PULS(886)
instruction is executed.
• Updated when pulse output
stops.
Pulse Output, Output
Completed Flag ON when the number of output pulses set with the
PULS(886) or PLS2(887) instruction has been output.
OFF: Output not completed.
ON: Output completed. Read-only • Cleared when power is turned
ON.
• Cleared when operation starts or
stops.
• Updated at the start or comple-
tion of pulse output in indepen-
dent mode.
Pulse Output, Output
In-progress Flag ON when pulses are being output.
OFF: Stopped
ON: Outputting pulses. Read-only • Cleared when power is turned
ON.
• Cleared when operation starts or
stops.
• Updated when pulse output
starts or stops.
