Inverter Positioning
Section 5-3
Use the following for the present values of the internal pulse and error counter
of inverter positioning.
A36 07 Error Counter Alarm
Flag ON: Error counter
alarm
OFF: No error
counter alarm
Turned ON at following times:
• When pulse output to error counter is
stopped and absolute value of error
counter present value is greater than
or equal to error counter alarm detec-
tion value
Turned OFF at following times:
• When error counter alarm is reset
• When power to CPU Unit is turned ON
• When CPU Unit operation starts
• When CPU Unit operation stops
This flag can be
used to provide
notification of
excessive pulses in
the error counter,
e.g., when encoder
wiring breaks dur-
ing positioning.
08 to 14 Not used.
15 Inverter Positioning
Output Value Sign
Flag ON:
OFF:
Turned ON at following times:
• When signed output value is between
0000 0000 and 7FFF FFFF hex.
Turned OFF at following times:
• When signed output value is between
FFFF FFFF and 8000 0000 hex.
This flag can be
used as a direction
signal.
A272 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
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.
A273 00 to 15 Upper 4 digits of the
present value of the
internal pulse output
(absolute value for
absolute coordi-
nates)

A32 00 to 15 Error counter 0
present value
(signed)
8000 to 7FFF hex
(
−
32,768 to
32,767)
Cleared to zero at following times:
• When power to CPU Unit is turned ON
• At start of operation
• When an error counter error occurs
Updated at following times:
• Cyclically according to error counter
cycle
Saved at following times:
• When Error Counter Disable Bit
(A562.01) is turned ON.
Use to monitor the
difference between
the target value
and the present
value.
A38 00 to 15 Lower 4 digits of
present value of
pulse output to
inverter (relative
value)
8000 0000 to 7FFF
FFFF hex
(
−
2,147,483,648 to
2,147,483,647)
Contains relative internal pulse output
value 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
• When pulse output to error counter is
started
Updated at following times:
• Cyclically on error counter cycle
These values can
be used to monitor
the present value
of internal pulse
output.
A39 00 to 15 Upper 4 digits of
present value of
pulse output to
inverter (relative
value)
