High-speed Counter/Pulse Output Instructions Section 3-21
Flags
Example When CIO 000000 turns ON in the following programming example,
PULS(886) sets the number of output pulses for pulse output 0. An absolute
value of 5,000 pulses is set. SPED(885) is executed next to start pulse output
using the CW/CCW method in the clockwise direction in independent mode at
a target frequency of 500 Hz.
3-21-6 SET PULSES: PULS(886) (CJ1M-CPU21/22/23 Only)
Purpose PULS(886) is used to set the pulse output amount (number of output pulses)
for pulse outputs that are started later in the program using SPED(885) or
ACC(888) in independent mode.
This instruction is supported by CJ1M-CPU21/22/23 CPU Units only.

Name Label Operation
Error Flag ER ON if the specified range for P, M, or F is exceeded.
ON if PLS2(887) or ORG(889) is already being executed
to control pulse output for the specified port.
ON if SPED(885) or INI(880) is used to change the mode
between continuous and independent output during pulse
output.
ON if SPED(885) is executed in an interrupt task when an
instruction controlling pulse output is being executed in a
cyclic task.
ON if SPEC(885) is executed in independent mode with
an absolute number of pulses and the origin has not been
established.
