Auxiliary Area Allocations by Address Appendix D
A276
and
A277 All Pulse Output
0 PV Contain the number of pulses output
from the corresponding pulse output
port.
PV range: 8000 0000 to 7FFF FFFF
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: 7FFF FFFF hex
PV after underflow: 8000 0000 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.
