Function
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
A323 contains the leftmost 4 digits
and A322 contains the rightmost 4
digits of the pulse output 2 PV.
A325 contains the leftmost 4 digits
and A324 contains the rightmost 4
digits of the pulse output 3 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.
This flag will be ON when pulses are
being output from pulse output 2
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
This flag indicates when an overflow
or underflow has occurred in the
pulse output 2 PV.
Cleared when operation starts.
OFF: Normal
ON: Overflow or underflow
ON when the number of output
pulses for pulse output 2 has been
set with the PULS(886) instruction.
Cleared when operation starts or
stops.
OFF: No setting
ON: Setting made
ON when the number of output
pulses set with the PULS(886) or
PLS2(887) instruction has been out-
put through pulse output 2.
Cleared when operation starts or
stops.
OFF: Output not completed.
ON: Output completed.
