PWM 891

4 posts in this topic

Hi everyone, im using CJ1M CPU21 ... I want to ask how to disable origin search function before I using PWM(891) instruction? This is because i noted that both PWM output 0 cannot share with the origin search function.

In CX-Programmer, this is done in the PLC Settings, under the Pulse Output tab.

The "Use define origin operation" to be unchecked, which is its default state.

Cycle the PLC power after changing any of the PLC settings.

NO. That's for setting up pulse outputs.

For PWM it is NOT necessary to make any changes in the PLC settings.

Simply configure the PWM instruction for the relevant output Port and desired frequency resolution [0.1 or 1.0 Hz].

Then use the Frequency and Duty Ratio to modify the PWM output pattern.
