5-3-4 Pulse Output Patterns
The following tables show the kinds of pulse output operations that can be
performed by combining various pulse output instructions.

Rightmost 4 digits A276 A278 A322 A324
Reset Bits
The pulse output PV will be cleared when
this bit is turned from OFF to ON.
0: Not cleared.
1: Clear PV.
A540.00 A541.00 A542.00 A543.00
CW Limit Input Signal Flags
This is the CW limit input signal, which is
used in the origin search.
ON when turned ON from an
external input. A540.08 A541.08 A542.08 A543.08
CCW Limit Input Signal Flags
This is the CCW limit input signal, which is
used in the origin search.
ON when turned ON from an
external input. A540.09 A541.09 A542.09 A543.09
Positioning completed input signals
This is the positioning completed input
signal, which is used in the origin search.
ON when turned ON from an
external input. A540.10 A541.10 A542.10 A543.10
Accel/Decel Flags
ON when pulses are being output accord-
ing to an ACC(888) or PLS2(887) instruc-
tion and the output frequency is being
changed in steps (accelerating or deceler-
ating).
0: Constant speed
1: Accelerating or decelerating
A280.00 A281.00 A326.00 A327.00
Overflow/Underflow Flags
ON when an overflow or underflow has
occurred in the pulse output PV.
0: Normal
1: Overflow or underflow
A280.01 A281.01 A326.01 A327.01
Output Amount Set Flags
ON when the number of output pulses has
been set with the PULS instruction.
0: No setting
1: Setting made
A280.02 A281.02 A326.02 A327.02
Output Completed Flags
ON when the number of output pulses set
with the PULS(886)/PLS2(887) instruction
has been output.
0: Output not completed.
1: Output completed.
A280.03 A281.03 A326.03 A327.03
Output In-progress Flags
ON when pulses are being output from the
pulse output.
0: Stopped
1: Outputting pulses.
A280.04 A281.04 A326.04 A327.04
No-origin Flags
ON when the origin has not been deter-
mined for the pulse output.
0: Origin established.
1: Origin not established.
A280.05 A281.05 A326.05 A327.05
At-origin Flags
ON when the pulse output PV matches
the origin (0).
0: Not stopped at origin.
1: Stopped at origin.
A280.06 A281.06 A326.06 A327.06
Output Stopped Error Flags
ON when an error occurred while output-
ting pulses in the origin search function.
0: No error
1: Stop error occurred.
