• The number of output pulses set to an SD device is valid for this instruction as well. The setting values are always read and
updated.
• When the specified number of output pulses is equal to or less than the number of pulses which have already been output,
pulse output stops after outputting pulses which are being output.
• When the specified number of output pulses is larger than the number of pulses which have already been output, pulse
output stops after outputting set number of pulses.
• When the number of output pulses is set from the no limitation output setting (number of output pulses is 0), the number of
output pulses is not updated (because outputting pulses continues or stops in the no limitation output).
• The maximum number of output pulses which can be output when the DPWM instruction is executed once (= maximum
value which can be set to an SD device) is "2147483647"
• The ON time and period can be set during the pulse output. Setting values are always read and updated.
• When the number of output pulses is 0 (no limitation output setting), the monitor of the current number of output pulses is
set to 0.
• When the number of output pulses is specified, the output pulses are monitored. When the DPWM output is executed
several times, the monitor of the number of output pulses is an integrated value.
• The monitor of the current number of output pulses can be changed during the pulse output.
• The monitor of the current number of output pulses is updated when the number of pulses is counted at the falling edge of
pulses in the positive logic and at the rising edge of pulses in the negative logic.
• When the output always remains ON or OFF, the monitor of the current number of output pulses does not change.
• The maximum value of the monitor of the current number of output pulses is "FFFFFFFFH". After the current number of
output pulses reaches the maximum value, the monitor of the current number of output pulses starts to count again from
"0".
