Built-in Analog Outputs (XA CPU Units Only)
CPU Bus Unit Flags/Bits
Pulse Output No-origin
Flag ON when the origin has not been determined and goes
OFF when the origin has been determined.
OFF: Origin established.
ON: Origin not established. Read-only • Cleared when power is turned
ON.
• Cleared when operation starts.
• Updated when pulse output
starts or stops.
• Updated each cycle during the
overseeing processes.
Pulse Output At-origin
Flag ON when the pulse output PV matches the origin (0).
OFF: Not stopped at origin.
ON: Stopped at origin. Read-only • Cleared when power is turned
ON.
• Updated each cycle during the
overseeing processes.
Pulse Output, Output
Stopped Error Flag ON when an error occurred while outputting pulses in the
pulse output 0 origin search function.
OFF: No error
ON: Stop error occurred. Read-only • Cleared when power is turned
ON.
• Updated when origin search
starts.
• Updated when a pulse output
stop error occurs.
PWM Output, Output
In-progress Flag ON when pulses are being output from the PWM output.
OFF: Stopped
ON: Outputting pulses. Read-only • Cleared when power is turned
ON.
• Cleared when operation starts or
stops.
• Updated when pulse output
starts or stops.
Pulse Output Stop
Error Code If a Pulse Output Stop Error occurs, the error code is writ-
ten to this word. Read-only • Cleared when power is turned
ON.
• Updated when origin search
starts.
• Updated when a pulse output
stop error occurs.
Pulse Output Reset Bit The pulse output PV will be cleared when this bit is turned
ON. Read/Write Cleared when power is turned
ON.
Pulse Output CW Limit
Input Signal Flag This is the CW limit input signal for the pulse output, which
is used in the origin search. To use this signal, write the
input from the actual sensor as an input condition in the lad-
der program and output the result to this flag. Read/Write Cleared when power is turned
ON.
Pulse Output CCW
Limit Input Signal Flag This is the CCW limit input signal for the pulse output,
which is used in the origin search. To use this signal, write
the input from the actual sensor as an input condition in the
ladder program and output the result to this flag. Read/Write Cleared when power is turned
ON.
Pulse Output Position-
ing Completed Signal This is the positioning completed input signal used in the
origin search for the pulse output. The input signal from the
servo driver is output to this bit from the ladder program to
enable using the signal. Read/Write Cleared when power is turned
ON.
Name Address Description Read/Write Updated
Analog Initialization
Completed Flag A434.04 ON while the built-in analog I/O is being initialized. Read-only When initialization is
completed
Name Address Description Access Updated
CPU Bus Unit Initialization
Flags A302.00 to
A302.15 These flags are ON while the corresponding CPU Bus
Unit is initializing after its CPU Bus Unit Restart Bit
(A501.00 to A501.15) is turned ON or the power is
turned ON.
Bits 00 to 15 correspond to unit numbers 0 to 15.
Use these flags in the program to prevent the CPU Bus
Unit’s refresh data from being used while the Unit is ini-
tializing. IORF(097) cannot be executed while an CPU
Bus Unit is initializing.
Read-only
CPU Bus Unit Restart Bits A501.00 to
A501.15 Turn the corresponding bit ON to restart (initialize) the
CPU Bus Unit with the corresponding unit number. Bits
00 to 15 correspond to unit numbers 0 to F. Read/write
