Pulse Output With Variable Duty Ratio
Change Duty Ratio
These functions set the position for outputting pulses (01000, 01001), the fre-
quency, and the duty ratio, and start the pulse outputs. By changing the duty ratio
setting and executing PWM(––) again, it is also possible to change the duty ratio
while pulse outputs with variable duty ratio are already in progress.

Note
The pulse outputs can also be stopped by switching the PC to PROGRAM
mode.
Read Pulse Output Status
This function reads the pulse output status.
