2-2 Allocations for Built-in CPU Unit Outputs
Select 1) General-purpose outputs, 2) Fixed duty ratio pulse outputs, or 3)
Variable duty ratio pulse outputs by executing the appropriate instruction, as
shown in the following table.
Note 1. General-purpose outputs 4 and 5 and PWM(891) outputs 0 and 1 cannot
be used when the PLC Setup has been set to enable the origin search
function for pulse outputs 0 and 1.
2. When the PLC Setup has been set to enable the origin search function,
outputs OUT4 and OUT5 are used as the Error Counter Reset Outputs and
inputs IN0 to IN5 are used as the Origin Inputs, Origin Proximity Inputs,
and Positioning Completed Signals. (Depending on the operating mode,
some of these I/O points may not be usable.)
3. PWM(891) output 1 can be used only with the CJ1M-CPU22/CPU23.
