• Operations when the PWM output is stopped (while the output pulse is off)
Output stop command
Period
OFF time setting
is 5 s or less
Period
OFF time setting
is 5 s or more
Period
OFF time setting
is 5 s or more
• The PWM output stops when SM8034 is on, and starts when SM8034 is off.
• PWM output does not stop, even if a pulse stop command for positioning is driven.
• 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. When driving PWM output by the HIOEN instruction, use the HIOEN instruction to turn PWM output off.
• 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.
8 APPLICATION INSTRUCTION
616
8.17 Pulse Related Instruction
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.
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
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.
OFF time setting
is 5 s or more
Output stop command is issued in 5 s
or more of the OFF width time.
5 s or
more
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.
OFF time setting
is 5 s or more
