- Pulse Width Modulation output
Function block
Description
Input
REQ: Executes PWM function block
CH: Sets the channel (0 ~ 1)
FREQ : Sets PWM output period (1 ~ 20,000ms)
DUTY : Sets Off Duty (0 ~ 100%)
Output
DONE: Turns On after the function block is executed without error, and
turns Off if an error occurs or there is no execution command.
STAT: Displays error status
