CJ2M CPU Unit Pulse I/O Module User’s Manual
* The duty ratio accuracy declines significantly at high frequencies because of limitations in the output circuit at
high frequencies.
*1 Terminals numbers on the XW2D-@@G@ Connector-Terminal Block Conversion Unit.
*2 If an origin search in operation mode 1 or 2 is used for an output port 0 to 3, an instruction error will occur.
