4. Cautions on counterpart equipment connected to high speed counter inputs
General-purpose inputs X000 to X007 (X003) are used for high speed counter inputs. An encoder
the output type shown in the table below can be connected depending on the connected terminal.
Encoders adopting the voltage output type and absolute encoders cannot be connected to high speed
counter inputs.
