25 HIGH-SPEED INPUT/OUTPUT FUNCTION
25.7 PWM Function
PWM output abnormal end flag
This device is for monitoring the end status (abnormal end) of PWM output.
■Corresponding devices
The device numbers corresponding to each channel are as follows.
■Update timing
The timing of device update is as follows.
The ON timing of the PWM output abnormal end flag includes startup of the PWM/DPWM, HIOEN/ DHIOEN
instruction.
Number of output pulses
The number of output pulses of PWM output is stored.
When "0" is set, output is continued without any limitation.
■Corresponding devices
The device numbers corresponding to each channel are as follows.
■Update timing
The timing to reflect the device in operation is as follows.
• When the HCMOV/DHCMOV instruction is executed (values updated immediately)
• When the PWM/DPWM instruction is executed
• END processing
■Clear timing
The timing when the device is cleared is as follows.
•STOP/PAUSERUN
• If the number of output pulses written is equal to or smaller than the number of pulses that have already
been output, pulse output is stopped after the pulses being currently output are completed.
• If the number of output pulses written is greater than the number of pulses that have already been output,
pulse output is stopped after the specified number of pulses are output.
• If the number of output pulses is set to "0" (output without any limitation), the value cannot be changed while
pulses are being output.
• The number of output pulses cannot be changed to "0" (output without any limitation) while pulses are being
output.

ON OFF
• At stop of pulse output due to an error in the setting value of the pulse width,
period, or output pulse count
• At stop of pulse output due to the relation of pulse width > period
• In the case of forced stop with SM8034 (all output disable) or output cannot
be started
•Power OFFON, reset, STOP/PAUSERUN
• When pulse output starts
• When turned OFF by the user
• After forced stop by SM8034 (all output disable), SM8034 is turned off, and
PWM output resumes (only when unlimited output)
