Name
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
Pulse Output This flag will be ON when pulses are being output accord-
Accel/Decel Flag 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
Pulse Output Over- This flag indicates when an overflow or underflow has
flow/Underflow Flag occurred in the pulse output PV.
OFF: Normal
ON: Overflow or underflow
Pulse Output, Output ON when the number of output pulses has been set with
Amount Set Flag the PULS(886) instruction.
OFF: No setting
ON: Setting made
Pulse Output, Output ON when the number of output pulses set with the
Completed Flag PULS(886) or PLS2(887) instruction has been output.
OFF: Output not completed.
ON: Output completed.
Pulse Output, Output ON when pulses are being output.
In-progress Flag
OFF: Stopped
ON: Outputting pulses.

Description
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.
