7 APPLICATION INSTRUCTION
7.14 Pulse related instruction
• Operations when the PMW output is stopped (while the output pulse is off)
• The PMW output stops when SM8034 is on, and starts when SM8034 is off.
• When the pulse output for positioning is driven, the PMW output does not stop.
• When specifying the number of output pulses, executing the PWM instruction, and then outputting pulses again after the
pulse output stops due to the completion of output of the specified number of pulses, turn OFF the contact which drove the
PWM instruction. If the PWM instruction was driven by the HIOEN instruction, stop the HIOEN instruction.
• When the period setting is equivalent to the ON time setting, the output always remains ON. The output ON state continues
even after “Period x Number of output pulses” is finished in this condition.
Error code
(SD0/SD8067)
Description
1810 The output destination specified by (d) is already used by another instruction (positioning instruction).
(The PMW output is not executed.)
A Y device is specified as the output destination specified by (d), and there is no unused channel number in the parameter setting.
3405 Y10 or later is specified as the output destination specified by (d).
(The PMW output stops.)
3600 A channel number that is not selected in the parameter setting are specified for the output destination specified by (d).
(The PMW output is not executed.)
3611(CH1)
3612(CH2)
3613(CH3)
3614(CH4)
The ON time specified by (s1) is larger than the period specified by (s2).
(The PMW output stops.)
The ON time or period is less than “1”.
The SD device specified for the number of output pulses stores a value outside the available range (0 to 2,147,483,647).
OFF time setting

OFF time setting
is 5 s or more
OFF time setting
is 5 s or more
OFF time setting

OFF time setting
is 5 s or less
Output stop command is issued
within 5 s of the OFF width time.
5 s or
less
5 s or
more
Output stop command is issued in 5 s
or more of the OFF width time.
When the OFF 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.
When the OFF 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.
If an output stop command is issued while the OFF
time setting is 5 s or less, outputting pulses stops
after the set OFF time elapses.
