Functions
PWM (Pulse-Width Modulation) is a digital output that can be used as an analog
output by controlling the duty cycle that contains a certain frequency. Duty cycle is a
ratio of the ON to OFF status in 1 cycle (pulse).
[Figure 6] Definition of PWM output and duty cycle
As illustrated above, the PWM controls the output from minimum to maximum
values by changing the duty cycle of the pulse.
CIMON PWM output module can be either general digital output or PWM output.
The general digital output can be used up to 32-pin points. From these 32-pin
points, a total of 12-pin points support PWM output. Also, you can prevent drastic
change of the frequency and duty cycle by using the ramp control.
