9-1-4 Ladder Program Example
This example shows how to use PWM output 0 to control the brightness of a light bulb.
Refer to 4-3-2 Wiring Examples for details on suppressing the load's inrush current and modify the cir-
cuit if necessary.
When the start input (CIO 2960.00) turns ON in this example, pulses with a duty ratio of 40% at a
frequency of 2,000 Hz are output from PWM output 0. When the stop input (CIO 2960.01) turns ON,
PWM output 0 is stopped.
