CW Limit Input
Signal Flag
This flag shows the status of the CW Limit
Input Signal, which is used in the origin
search.
The status of the signal from the CW limit
input sensor connected to a normal input
must be written to A540.08 or A541.08.
ON when turned ON
from an external input.
A540.08 A541.08
CCW Limit Input
Signal Flag
This flag shows the status of the CCW
Limit Input Signal, which is used in the ori-
gin search.
The status of the signal from the CCW
limit input sensor connected to a normal
input must be written to A540.09 or
A541.09.
ON when turned ON
from an external input.
A540.09 A541.09
Positioning com-
pleted input signal
This flag shows the status of the position-
ing completed input signal, which is used
in the origin search.
The status of the Positioning Completed
Signal from the Servo Drive connected to
a normal input must be written to A540.10
or A541.10.
ON when turned ON
from an external input.
A540.10 A541.10
Accel/Decel Flag ON when pulses are being output accord-
ing to an ORG, ACC or PLS2 instruction
and the output frequency is being
changed in steps (accelerating or deceler-
ating).
0: Constant speed
1: Accelerating or decel-
erating
A280.00 A281.00
Overflow/Underflow
Flag
ON when an overflow or underflow has
occurred in the pulse output PV.
0: Normal
1: Overflow or underflow
A280.01 A281.01
Output Amount
Set Flag
ON when the number of output pulses has
been set with the PULS instruction.
0: No setting
1: Setting made
A280.02 A281.02
Output Completed
Flag
ON when the number of output pulses set
with the PULS/PLS2 instruction has been
output.
0: Output not completed.
1: Output completed.
A280.03 A281.03
Output In-progress
Flag
ON when pulses are being output from
the pulse output.
0: Stopped
1: Outputting pulses.
A280.04 A281.04
No-origin Flag ON when the origin has not been defined
for the pulse output.
0: Origin defined.
1: Origin undefined.
A280.05 A281.05
At-origin Flag ON when the pulse output PV matches
the origin (0).
0: Not stopped at origin.
1: Stopped at origin.
A280.06 A281.06
Output Stopped
Error Flag
ON when an error occurred while output-
ting pulses in the origin search function.
0: No error
1: Stop error occurred.
A280.07 A281.07
Stop Error Code When a Pulse Output Stop Error occurs,
the error code is stored in that pulse out-
puts corresponding Stop Error Code
word.
