Panasonic AFPX-C30T - PWM Output Function (Pulse IO Cassette)

9.5 PWM Output Function (Pulse I/O Cassette)
9.5.1 Overview of PWM Output Function
PWM output function
With the F173 (PWMH) instruction, the pulse width modulation output of the specified duty ratio is
obtained.
System register setting
When using the PWM output function, set the channel corresponding to the system register 402 to
“PWM output”.
Note:
The pulse I/O cassette (AFPX-PLS) cannot be used with the FP-X Tr type.
