PWM Output Function
What is PWM Output Function?
●
PWM output function enables change of output Duty at any
frequency by 1% unit within the range of 0 to 100%.
Available frequency range is 1Hz to 30kHz, and setting unit is 1Hz.
●
Pulse I/O unit provides up to 4CH PWM output.
But user must choose between PWM and pulse output, so if pulse
output is selected, the number of CH for PWM output is decreased.

Settings for PWM output, such as output
frequency, are configured in shared memory.
After shared memory data is configured,
pulse output starts when PWM control
signal is turned on by I/O operation.

Pulse output (pulse, PWM) consists of 4CH as described
below.
• CH 0: PLS0 output or PWM0 output
• CH 1: PLS1 output or PWM1 output
• CH 2: PLS2 output or PWM2 output
• CH 3: PLS3 output or PWM3 output
