Note Present Values of High-speed Counter and Pulse Outputs
The present value of the high-speed counter when inverter positioning is used
is stored in the same memory location as for normal high-speed counter appli-
cation. This value can be used as the present value of feedback pulses from
the encoder, i.e., as the absolute position of inverter positioning. Target value
and range comparisons for high-speed counters are also valid.
The present value of the pulse output (A276/A277 or A278/A279), i.e., the
pulse output value to the error counter, is an absolute position if an absolute
coordinate system is specified and is a relative position if a relative coordinate
system is specified.
Refresh timing
Contains absolute movement value
from the internal pulse origin when
pulses are output to error counter.
Cleared to zero at following times:
• When power to CPU Unit is turned ON
• When operation is started
Updated at following times:
• Cyclically on error counter cycle
Data range
Turned ON: Error counter 0
present value (A22) reset and
Error Counter Error Flag cleared.
While ON: Error counter value
held.
Turned ON: Error counter 0
present value (A32) reset and
Error Counter Error Flag cleared.
While ON: Error counter value
held.

Application
examples
This value can be
used to monitor the
present value of
the internal pulse
output as an abso-
lute value when
using absolute
coordinates.
