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.)
• Specify 2
s or more in Y0 to Y3 and 200
s or more in Y4 to Y7 for the ON time specified by (s1), and specify 5
s or more
in Y0 to Y3 and 400
s or more in Y4 to Y7 for the period specified by (s2).
• When a channel number that is not selected for the PMW output in the parameter setting is specified for (d), this instruction
is not executed. An operation error occurs.
• Operations when the PMW 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.
