Precautions
• Specify the ON time by (s1) and the period by (s2) so that [(s2)-(s1)] is equal to or larger than 3
s.
• When a negative value is specified for the ON time by (s1) and the period by (s2), an operation error occurs. (In 16-bit
instruction PWM, no error occurs.)
• For the ON time specified by (s1), specify 2
s or more in Y0 to Y3 of the CPU module and the output of the high-speed
pulse input/output module, and 200
s or more in Y4 to Y7 of the CPU module. For the period specified by (s2), specify 5
s or more for Y0 to Y3 in the CPU module and the output of the high-speed pulse input/output module, and 400
s or more
in Y4 to Y7 of the CPU module.
• When a channel number that is not selected for the PWM output in the parameter setting is specified for (d), this instruction
is not executed. An operation error occurs.
• Do not specify the channel numbers of the high-speed pulse input/output module (5 to 12) in a program with interrupt
priority set to "1".
• Operations when the PWM output is stopped (while the output pulse is on)
Period
Output stop command
If an output stop command is issued while the ON
time setting is 5
s or less, outputting pulses
stops after the set ON time elapses.
When the ON time setting is 5
s or more and 5
s or
less time has elapsed when an output stop command is
issued, outputting pulses stops in 5
s from the stop
command.

5
s
or less
Output stop command is issued
within 5
s of the ON width time.
5
s or
more
Output stop command is issued in
5
s or more of the ON width time.
When the ON time setting is 5
s or more and 5
s or
more time has elapsed when an output stop command is
issued, outputting pulses stops with the stop command.
