Panasonic GM1 - Data Update Timing (Duty Ratio); PWM Output Setting Example

12.5.5 Data Update Timing (Duty Ratio)
The data update timing for duty ratios during PWM output is descried below.
■
Data update at the rising edge of start request bit
In this mode, the duty ratio to be changed is written to the duty ratio set value and updated with
data at the point in time when the start request bit is switched from OFF to ON. The duty ratio
changed in this timing is reflected at the falling edge of the pulse that is being output.
No. Name Description
(1) Data update timing Indicates the timing in which the duty ratio set value is reflected
(2) Output update timing
Indicates the timing in which the changed duty ratio is reflected
as actual output
12.5.6 PWM Output Setting Example
■
Overview
PWM output is performed. It is controlled by the switch input (X0 or X1) connected to the GM1
controller
. If the start request bit is turned ON when the enable request bit is ON, PWM output
will be started.

Settings in GM Programmer
For example, to set PWM output for Y4, use the procedure in "12.5.2 Setting Output Ports with
GM Programmer" to configure settings as shown below.
