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.

A278 00 to 15 Lower 4 digits of the

present value of the

internal pulse output

(absolute value for

absolute coordi-

nates)

8000 0000 to 7FFF

FFFF hex

(−2,147,483,648 to

2,147,483,647)

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

This value can be

used to monitor the

present value of

the internal pulse

output as an abso-

lute value when

using absolute

coordinates.

A279 00 to 15 Upper 4 digits of the

present value of the

internal pulse output

(absolute value for

absolute coordi-

nates)
